Fuzzy Based Optimal QoS Constraint Services Composition in Mobile Ad Hoc Networks

In recent years, computational capability of mobile devices such as Laptops, mobile phones, PDAs, etc., are greatly improved. Implementation of SOA ("Service Oriented Architectures") in mobile ad hoc networks increases the flexibility of using mobile devices. On composing different available services to satisfy end user requirement is a critical challenge in MANETs ("Mobile Ad Hoc Network") due to dynamic topology, Resource heterogeneity, Band width constraint and highly distributed service providers. Existing composition services approaches are not suitable for MANETs due to lack of constraints consideration while choosing services. In this paper, we proposed Fuzzy based optimal QoS constrained Service Composition in MANETs. We consider Energy constraint, hop count, Response time & service throughput as QoS Constraints composing optimal services. We proposed fuzzy logic based system to provide rating to the services for optimal selection of services. We also considered that each node can provide one or more services. The service composition failure rate will be reduced by selecting optimal services in available services. The simulation result demonstrates that the proposed method outperformed than the traditional AODV in terms of average packet delay, energy constraint, throughput and turnaround time

SOA Governance – Road into Maturity

There is a general consensus that SOA benefits could be reached but it is unclear how to achieve this. Research shows that the problems with SOA governance in practice are among the major reasons of SOA failures. Based on a literature review, this study first proposes a list of SOA aspects to be considered when implementing SOA governance. By adopting an interpretive research methodology based on interviews, this research paper makes two contributions: it addresses the practical matters that are major concerns for organisations to achieve a higher maturity level with their SOA, and it reveals the importance of the key SOA aspects in building strong governance and consequently reaching a higher maturity level. The expected result should deliver a theoretical contribution to SOA maturity in relation to SOA governance; it could provide organisations with new awareness in assessing their level of maturity and provide recommendations

Factors Affecting The Organizational Adoption Of Service-Oriented Architecture (Soa)

Service-oriented computing is an emerging IT innovation. Among its manifestations is service-oriented architecture (SOA), an architectural approach to designing and implementing IT solutions. Academic empirical research on SOA adoption is scarce, with many studies focussing on qualitative analysis. The purpose of this study is to explore SOA adoption using a quantitative approach. This study investigates organizational SOA adoption in South Africa from DOI theory and TOE framework perspectives. A comprehensive model of SOA adoption is presented along with an associated research instrument. In order to validate the instrument and to gauge the state of SOA adoption, an online survey was conducted among South African organizations. The results of the survey highlight a number of factors influencing SOA adoption. Use of multiple standards and platforms, complexity, compatibility, cost, top management support, good governance and strategy, adequate human and financial resources, vendor support for integration and development tools are all significant factors for a fruitful SOA implementation. The findings of this study can contribute to the body of knowledge on organizational SOA adoption and create opportunities for future related research in this field

DEPLOYING RESOURCES TO SAVE LIVES: PARTNERS TELE-STROKE SERVICE

Innovative ICT applications such as patient-present telemedicine consultation services can save lives, yet following pilot-testing few have achieved long-term viability. Partners Health Care’s TeleStroke service, in full operation, is financially self-sustaining. Interviews with clinical, technical and administrative personnel at Partners and two “spoke” hospitals revealed practical lessons learned. Analysis through the lens of the Resource Based View reveals that many valuable assets and capabilities that Partners and its spoke hospitals developed are necessary for a successful TeleStroke program yet could be acquired or copied (they are not rare or inimitable). We note further that Partners’ overriding goal for TeleStroke is to achieve clinical success in its catchment area, without depleting financial resources; competitive advantage is sought within the catchment area but not beyond it. Resource analysis reveals that other institutions could develop successful telemedicine services for acute stroke care, since the needed assets are readily available, most of the capabilities can be imitated, and viable substitutes are limited. We contend that the lessons learned in this case study -- about the effective deployment of assets and capabilities -- are broadly applicable to other settings, in health care and other industries

A Three Level Model of SOA Maturity: Toward Achieving Sense and Respond

Service Oriented Architecture (SOA) has been proposed as both a technical and managerial solution in making firms more agile in addressing ever changing business needs. This conceptual paper identifies 3 levels of SOA implementation maturity: 1. Stability, 2. Flexibility, 3. Sense and Respond. A process and governance strategy on how to achieve each level is theorized and supported by case examples. The highest level conceptualized, Level 3, holds promise whereby SOA intelligence informates business activities and decisions. A case illustration concerning the use of a Customer Priority Index (CPI), derived from Level 3 SOA, outlines how a customer focused Sense and Respond capability might be achieved

Service-oriented Architecture Projects in Practice: A Study of a Shared Document Service Implementation

Published version of an article in the journal: Procedia Technology. Also available on Science Direct: http://dx.doi.org/10.1016/j.protcy.2014.10.017This paper reports on a case study focusing on service-oriented architecture (SOA) projects in practice. The aim of these projects has been to develop a shared document service supporting different business divisions in a large Norwegian governmental institution. The research question guiding this research is: How are SOA projects carried out in practice? What are the challenges of developing shared services in service-oriented architecture? SOA projects are accompanied by a complex socio-technical system development environment. In the present study we followed parallel system development processes and identified several issues associated with competence requirements, distributed coordination principles and control, lack of communication, tuning of parallel projects, and selection of appropriate project management approaches and system development methods. Clearly, there was a difference between undertaking a system development project within one organizational unit (silo) compared to the development of shared services to provide support across a large organization. Findings demonstrate that the complexity of SOA projects was underestimated by the project managers, and ad hoc governance was practiced in terms of control, coordination, and communication. To capture the entire system development context of an SOA project, a holistic approach and mind-set comprising time management and fine tuning of all parallel SD activities is necessary. Organizational maturity to carry out SOA projects is also of significance. The study has implications for SOA adopters in general and for system developers and project managers working in an SOA context in particular

Understanding organizational traps in implementing service-oriented architecture

Thesis (S.M. in Management Research)--Massachusetts Institute of Technology, Sloan School of Management, 2013.Cataloged from PDF version of thesis.Includes bibliographical references (p. 57-63).One of the major objectives of implementing service-oriented architecture (SOA) is to enhance IS agility and improve IT-business alignment. However, the contradictory experiences about SOA implementation turn out to be a paradox: why many organizations failed to meet their expectations about SOA implementation efforts, while others succeeded? Contrast to prior research on SOA, this study adopts the process perspective and provides plausible theoretical explanations for the "SOA implementation paradox". The study uses multiple case studies and literature review to develop a system dynamics model which highlights the feedback loops and time delay during the SOA implementation process. The results reveal the dynamic characteristics of learning curve of SOA implementation and two organizational traps (technology learning trap and implementation effectiveness trap) associated with SOA implementation. The theory of the organizational traps can be generalized to a broad context of innovative IS implementation. Further, the theoretical causes of the traps are discussed.by Xitong Li.S.M.in Management Researc

Factors affecting adoption of service -oriented architecture (SOA) at an enterprise level

Includes bibliographical references (leaves 104-112).Service-oriented computing is an emerging IT innovation. Among its manifestations is service-oriented architecture (SOA), an approach to designing and implementing IT solutions. Organizations adopting SOA are facing implementation challenges. Examining factors affecting SOA adoption at an organizational level can reduce uncertainty about SOA, its advantages and disadvantages, and implementation issues. This study uses quantitative analysis to investigate organizational SOA adoption in South Africa from DOI theory and TOE framework perspectives. Results highlight a number of factors influencing SOA adoption: use of multiple standards and platforms, complexity, compatibility, cost, top management support, good governance and strategy, adequate human and financial resources, vendor support for integration and development tools
