Evaluating the Security of Mobile Agent Platforms
Mobile agents are software entities that can migrate autonomously throughout a network
from host to host. This means they are not bounded to the platform they begin execution. This feature
of agents makes them a very attractive technology, and in fact it has been argued many times in the
literature that mobile agents help to reduce network traffic and perform tasks more efficient.
However, security issues have not yet been fully investigated and in fact, mobile agent platforms
sometimes they neglect the security issues involved with agent mobility. This paper presents a
security related evaluation of 8 main mobile agent platforms
The Application of Fuzzy Logic Controller to Compute a Trust Level for Mobile Agents in a Smart Home
Agents that travel through many hosts may cause a threat on the security of the visited hosts. Assets,
system resources, and the reputation of the host are few possible targets for such an attack. The
possibility for multi-hop agents to be malicious is higher compared to the one-hop or two-hop
boomerang agents. The travel history is one of the factors that may allow a server to evaluate the
trustworthiness of an agent. This paper proposes a technique to define levels of trust for multi-hop
agents that are roaming in a smart home environment. These levels of trust are used later to
determine actions taken by a host at the arrival of an agent. This technique uses fuzzy logic as a
method to calculate levels of trust and to define protective actions in regard to those levels
A trustworthy mobile agent infrastructure for network management
Despite several advantages inherent in mobile-agent-based approaches to network management as compared to traditional SNMP-based approaches, industry is reluctant to adopt the mobile agent paradigm as a replacement for the existing manager-agent model; the management community requires an evolutionary, rather than a revolutionary, use of mobile agents. Furthermore, security for distributed management is a major concern; agent-based management systems inherit the security risks of mobile agents. We have developed a Java-based mobile agent infrastructure for network management that enables the safe integration of mobile agents with the SNMP protocol. The security of the system has been evaluated under agent to agent-platform and agent to agent attacks and has proved trustworthy in the performance of network management tasks

MAS platforms as an enabler of enterprise mobilisation: The state of the art
One of the main application areas for multi-agent systems technology is enterprise mobilization, wherein the main business process actors are nomadic workers. An agent's autonomy, sociality and intelligence are highly prized features when it comes to supporting those mobile workers who are geographically isolated from the main knowledge source (i.e. the corporate Intranet) and are frequently moving from one location to another. Based on experience gained from two field trials of applications (built using for multi-agent systems technology and running on lightweight handheld devices) that support mobile business processes for telecommunications service provisioning and maintenance, this paper proposes desirable metrics for any multi-agent systems platform intended for enterprise mobilisation use. These metrics are then used to compare a number of existing multi-agent systems platforms, and based on the results, this paper identifies some areas for improvement
A Survey on Service Composition Middleware in Pervasive Environments
The development of pervasive computing has put the light on a challenging problem: how to dynamically compose services in heterogeneous and highly changing environments? We propose a survey that defines the service composition as a sequence of four steps: the translation, the generation, the evaluation, and finally the execution. With this powerful and simple model we describe the major service composition middleware. Then, a classification of these service composition middleware according to pervasive requirements - interoperability, discoverability, adaptability, context awareness, QoS management, security, spontaneous management, and autonomous management - is given. The classification highlights what has been done and what remains to do to develop the service composition in pervasive environments
Airline E-commerce user experience experiment: An investigation of Thai LCCs passengers' purchasing behaviour among different online platforms
Purpose: This study examines the current state of the airlineâs e-commerce platforms and seek to identify their benefits and disadvantages in the aspect of user experience. Design/methodology/approach: The study commenced by first reviewing the literatures on actual sale figure from the studied Thai LCC, user interface (UI) and user experience (UX). It then proceeded to gather the empirical evidences using questionnaires from 135 active air passengers who have online purchasing experience. The composite findings from literature review and surveys were then used to design and apply for the final phase which is a series of in-depth interviews of air passengers on their usability test sessions and experts from the related industries. Coding and clustering was utilised to analyse the qualitative data obtained. Findings: The study examines the differences in online ticket purchasing platforms including airline's website, mobile-site and mobile application. The results identified five areas of factors: physical, trust, willingness to learn, context of use and adjustment. With regard to these factors, there are no single platform that outperform others. Airlines need to ensure that UX/UI of all platforms meet the usersâ requirements in all circumstances. Originality/value: The study reveals the customer thinking processes on online purchasing behaviour. It focuses on web-usability and user experience of different booking platforms. The findings allow the subjected LCC to improve customer experience and optimise its platforms. The paper could also benefit other entrepreneurs who are in the related industry or similar contexts. In addition, the study of user-experience in the context of airline industry, particularly in the emerging countries like Thailand is limited.Peer Reviewe

This paper aims to introduce a consolidated report of thriving security on mobile application platforms and providing knowledge of vital threats to the users and enterprises. Furthermore, in this paper, various techniques as well as methods for security measurements, analysis and prioritization within the peak of mobile platforms will be presented. Additionally, increases understanding and awareness of security on mobile application platforms to avoid detection, forensics and countermeasures used by the operating systems. Finally, this study also discusses security extensions for popular mobile platforms and analysis for a survey within a recent research in the area of mobile platform security
Web Service Testing and Usability for Mobile Learning
Based on the summary of recent renowned publications, Mobile Learning (ML) has become an emerging technology, as well as a new technique that can enhance the quality of learning. Due to the increasing importance of ML, the investigation of such impacts on the e-Science community is amongst the hot topics, which also relate to part of these research areas: Grid Infrastructure, Wireless Communication, Virtual Research Organization and Semantic Web. The above examples contribute to the demonstrations of how Mobile Learning can be applied into e-Science applications, including usability. However, there are few papers addressing testing and quality engineering issues â the core component for software engineering. Therefore, the major purpose of this paper is to present how Web Service Testing for Mobile Learning can be carried out, in addition to re-investigating the influences of the usability issue with both quantitative and qualitative research methods. Out of many mobile technologies available, the Pocket PC and Tablet PC have been chosen as the equipment; and the OMII Web Service, the 64-bit .NET e-portal and the GPS-PDA are the software tools to be used for Web Service testing
