Trust-based Service Composition and Binding for Tactical Networks with Multiple Objectives

Abstract —Tactical networks must select service providers to meet service requirements of an operation while facing resource constraints and high security vulnerability. In such an environment nodes provide services to support various operations and / may request services to support the operations as well. We formulate the problem of service composition and service binding as a multi-objective optimization (MOO) problem, minimizing the service cost, while maximizing the quality of service (QoS) and quality of information (QoI). The MOO problem is essentially a node-to-service assignment problem such that by dynamically formulating service composition, and selecting the right nodes to provide requested services, the network can support concurrent operations while achieving multiple system objectives. We develop a trust-based service composition and binding protocol. We demonstrate that the trust-based scheme outperforms the counterpart non-trustbased scheme. Furthermore, our trust-based scheme can effectively penalize malicious nodes performing self-promotion attacks, thus filtering out malicious nodes and can ultimately lead to high user satisfaction. Keywords—service composition, tactical networks, trust, multiobjective optimization. I

Understanding community policing

Purpose The purpose of the paper is to explore, in broad terms, how policing needs to be developed in communities today. Approach The approach is normative and analytical, considering the meaning of policing in general, and community policing in particular, and specifying the criteria that such policing has to satisfy in order to be fair and effective in contemporary society. Findings A concept of public self-policing is developed and community policing is then evaluated in the light of this concept. Police officers are understood as street-level bureaucrats, with multiple accountabilities. The ideal relationship between police and public is characterised as a structural coupling between two types of self-organising system. Implications The paper has implications for how policing organisations and governments might develop improved policing strategies in the future. Value of the paper The paper provides a clear, logical summary of thinking about the role of policing, particularly community policing, in today’s society. It offers a novel concept of public self-policing, leading to a new approach to the evaluation of the work of policing organisations

Decision Taking for Selling Thread Startup

Decision Taking is discussed in the context of the role it may play for a selling agent in a search market, in particular for agents involved in the sale of valuable and relatively unique items, such as a dwelling, a second hand car, or a second hand recreational vessel. Detailed connections are made between the architecture of decision making processes and a sample of software technology based concepts including instruction sequences, multi-threading, and thread algebra. Ample attention is paid to the initialization or startup of a thread dedicated to achieving a given objective, and to corresponding decision taking. As an application, the selling of an item is taken as an objective to be achieved by running a thread that was designed for that purpose

ERP implementation methodologies and frameworks: a literature review

Enterprise Resource Planning (ERP) implementation is a complex and vibrant process, one that involves a combination of technological and organizational interactions. Often an ERP implementation project is the single largest IT project that an organization has ever launched and requires a mutual fit of system and organization. Also the concept of an ERP implementation supporting business processes across many different departments is not a generic, rigid and uniform concept and depends on variety of factors. As a result, the issues addressing the ERP implementation process have been one of the major concerns in industry. Therefore ERP implementation receives attention from practitioners and scholars and both, business as well as academic literature is abundant and not always very conclusive or coherent. However, research on ERP systems so far has been mainly focused on diffusion, use and impact issues. Less attention has been given to the methods used during the configuration and the implementation of ERP systems, even though they are commonly used in practice, they still remain largely unexplored and undocumented in Information Systems research. So, the academic relevance of this research is the contribution to the existing body of scientific knowledge. An annotated brief literature review is done in order to evaluate the current state of the existing academic literature. The purpose is to present a systematic overview of relevant ERP implementation methodologies and frameworks as a desire for achieving a better taxonomy of ERP implementation methodologies. This paper is useful to researchers who are interested in ERP implementation methodologies and frameworks. Results will serve as an input for a classification of the existing ERP implementation methodologies and frameworks. Also, this paper aims also at the professional ERP community involved in the process of ERP implementation by promoting a better understanding of ERP implementation methodologies and frameworks, its variety and history

A gap analysis of Internet-of-Things platforms

We are experiencing an abundance of Internet-of-Things (IoT) middleware solutions that provide connectivity for sensors and actuators to the Internet. To gain a widespread adoption, these middleware solutions, referred to as platforms, have to meet the expectations of different players in the IoT ecosystem, including device providers, application developers, and end-users, among others. In this article, we evaluate a representative sample of these platforms, both proprietary and open-source, on the basis of their ability to meet the expectations of different IoT users. The evaluation is thus more focused on how ready and usable these platforms are for IoT ecosystem players, rather than on the peculiarities of the underlying technological layers. The evaluation is carried out as a gap analysis of the current IoT landscape with respect to (i) the support for heterogeneous sensing and actuating technologies, (ii) the data ownership and its implications for security and privacy, (iii) data processing and data sharing capabilities, (iv) the support offered to application developers, (v) the completeness of an IoT ecosystem, and (vi) the availability of dedicated IoT marketplaces. The gap analysis aims to highlight the deficiencies of today's solutions to improve their integration to tomorrow's ecosystems. In order to strengthen the finding of our analysis, we conducted a survey among the partners of the Finnish IoT program, counting over 350 experts, to evaluate the most critical issues for the development of future IoT platforms. Based on the results of our analysis and our survey, we conclude this article with a list of recommendations for extending these IoT platforms in order to fill in the gaps.Comment: 15 pages, 4 figures, 3 tables, Accepted for publication in Computer Communications, special issue on the Internet of Things: Research challenges and solution

Power battles in ICT standards-setting process : lessons from mobile payments

Standards play an important role in ICT innovation to ensure the interoperability and interconnectivity. However, standardisation is a complex process that involves actors with different interests. Various studies, which are mainly economics, have tried to develop the standards-setting process models. One of the models proposes that standardisation can be distinguished into two main stages, i.e., the pre-standardisation stage and the standardisation stage (Smits, 1993). The distinction is based on the different players involved in each stage. The pre-standardisation stage is the period when the players involved are mostly the firms who have developed a new technological specification or requirement, which they want to become the standard. In this period, they draft proposals or recommendations for submission to a formal standards body. If accepted, the proposal or recommendation becomes a working item within the Technical Committee or Working Group of the standards body. This marks the beginning of the standardisation stage. The outcome of the pre-standardisation stage may, on the other hand, be made publicly available and become the market standard. If this is happens, there is no standardisation stage, and the process becomes de facto standardisation. The early stage of standardisation is considered to be the most important period in the standards-setting process for a number of reasons, the main one being that the dynamics and the interactions among actors during the early period may influence the process and the outcome. Various activities take place in this period, such as information gathering, lobbying, and informal meetings. These initial actions reveal the interactions among involved actors that have a substantial impact on the entire standards-setting process. Power is a factor that shapes the dynamics of these interactions. However, little research has been undertaken to explore this dynamics. This study, thus represents an effort to redress this, by exploring the mechanism of standardisation and the interactions that take place among the parties involved. To be precise, this study explores the power battles among the negotiating parties during the standards-setting process. The main research question of this study can be formulated as: How do the power battles shape the process of standards-setting in ICT industry? Qualitative case study research has been chosen as the research methodology. The qualitative case study consists of case selection and data collection, which includes interviews and documentation from technical report, white papers, news, to company profiles. Prior to the case study activities, literature survey on standardisation and negotiation, which is a part of desk research, has been conducted and serves as the knowledge source and the theoretical framework of this study. In addition, literature survey can also be used as a secondary source of data. Negotiation theory has been used to deliberate the concept of power. For the empirical part, the aspect of the ICT industry that has been chosen is Mobile Payments. The development of Mobile Payments, defined as an activity that occurs between two parties utilising a combination platform Power Battles 222 in ICT Standards-Setting Process between financial and mobile communications, is still in the conceptual and trial period, which means that as yet no standards have been defined. This provides an ideal context in which to track the process of standardisation and all it involves. Moreover, different sectors are involved in this emerging technology, which means a variety of power based negotiations are likely to occur. Therefore, five Mobile Payments developing organisations are revealed as the arena and discussed as the case studies. They are the Mobile Payment Forum, Mobey Forum, Simpay, PayCircle, and ECBS. Mobile Payments can be seen as a result of an innovation in a service industry. By definition, Mobile Payments is an incremental innovation, that is, a new technology that offers improved performance in payment method offered by payment institutions through mobile devices and networks. Mobile Payments is an improved service and a new method of payment, which involves services from the financial and mobile communications industries. Mobile Payments involves the telecommunications and the financial industries. Both industries have several existing standards, supported by powerful parties, and both industries are themselves powerful parties. As a result, standards development for Mobile Payments is being shaped by two powerful parties from different industries. Standards-setting for Mobile Payments thus is an inter-industry battleground, hence the current absence of standards for Mobile Payments. Various actors have made attempts to set standards for Mobile Payments. Mobile Payments is in the beginning and early period of the standards-setting process, in which only related firms are involved. Negotiation and informal meetings between parties occur during this stage, and an agreement among actors about certain solutions would be generated to proceed to the next level. For de facto standardisation, the agreement would be standards launched on the market. In the case of de jure standardisation, the agreement takes the form of a proposal, which must be examined and accepted as the working project by the formal standards body. The two major industry groups involved in Mobile Payments initiated various organisations. Financial industry initiatives resulted in the Mobile Payment Forum, the Mobey Forum and the European Committee for Banking Standards (ECBS). Initiatives from the telecommunications industry resulted in the establishment of what eventually became known as Simpay. In addition to these initiatives from the two major industries, the IT industry group representing manufacturers and vendors – launched PayCircle. Although competing to each other, these groups are inter-related. A number of firms join more than one group, playing a different role in each. For instance, in one group, a firm might be a Board member whilst it might only be an Associate member of another. Grindley (1995) calls these types of alliances cross-membership. It represents a strategic movement, designed to monitor the activities of others in the various fora. In Mobile Payments standardisation, four power types can be identified. These types of power are exercised by the different categories of actors in negotiating standards-setting process; they are legitimate power, expert power, referent power, and informational power. Legitimate power is possessed by the founder of consortia, and reflected from the leadership privilege in decision-making. Expert power is characterised by the expertise in particular area and technological know-how mostly possessed by the manufacturers. The expert power provides them to propose the preferred architecture of Mobile Payments. Referent power is acquired through reputation and influential individual, which is performed well by service oriented organisations. Related Summary 223 information, for instance on the current development on Mobile Payments, provides knowledge to the information possessor, and leads to the informational power. In this case, the typical possessors of informational power are network operators and credit-card companies. The existence of different Mobile Payments developing groups introduces competition at consortium level. The competition between groups affects the power battles among them. Each organisation has different power types, which produce different power dominance. The differences lie in the different membership composition. Mobile Payment Forum is a business and policy oriented consortium, which is reflected in the variety of its membership composition. Mobey Forum is a technically oriented consortium, whose concern is to implement mobile technologies for financial services. Simpay is a commercial and profit oriented group, and is registered as a UK-based company. PayCircle is a technically oriented consortium as exemplified by its membership. And ECBS is a policy-oriented organisation, which is evident from its membership composition and structure. Moreover, ECBS acts as regulator in the banking sector. The power battles among these organisations reveal certain characteristics. Although all Mobile Payments organisations possess expert power, this varies in type depending on the expertise of their members. For instance, although Mobey Forum and PayCirlce are both technically oriented, they have different approaches and different expertise. Although the Mobile Payment Forum and ECBS are both policy-oriented organisations, ECBS has more legitimate power than Mobile Payment Forum because the Mobile Payment Forum is a business-oriented group, which implements its legitimate power within the organisation, while ECBS has legitimate power over external organisations. The result of these power battles is the multiple types of Mobile Payments being developed by the various organisations. The first type is a bank-account-based system, which is also known as wallet-based Mobile Payments. Mobey Forum is the developer of this system, which reflects the expert power of its founders. This payment system is also supported by PayCircle and ECBS, which indicates referent power among these three organisations. The second type is a telco-billing-based system, which is being developed by Simpay. Simpay’s persistence in pursuing this system demonstrates its expert power; its founders are the leading mobile network operators. In addition, this development shows the legitimate power of Simpay’s founder. When developing this system, Simpay demonstrates its informational power in approaching banks to become members. Simpay’s informational power is based on its understanding of the importance of payment systems to banks. However, the commission rate in Simpay’s proposed architecture is too high, which makes it difficult for them to accept the architectures being proposed by the banks. Simpay’s proposed architecture is similarly not supported by other organisations. The third type is credit-card-based, and is being developed by the Mobile Payment Forum. This type of development by the Mobile Payment Forum demonstrates the legitimate power of its founders. Moreover, it also exemplifies the expert power of the founders, which are the leading credit-card institutions. The fact that the Mobile Power Battles 224 in ICT Standards-Setting Process Payment Forum is the most heterogeneous Mobile Payments developing organisation, demonstrates that it has referent power. From the three different types of Mobile Payments being developed, it is obvious that there is a conflict of interests among the involved parties. Each of them would like to gain the maximum outcome by becoming the technological leader through dominant design in the market. As a result, different technologies compete and create the power battles among them. Therefore, one may conclude that the power battles in standardssetting process cause technology variation and lead to the uncertainty of the standards for the technology in question
