“…TCOT is claimed to have improved performance and throughput over 2PC protocol in managing mobile transactions. 2PC protocol enforces classical ACID criteria [15]. As described above 2PC and ACID criteria are inappropriate for M-services transactions.…”

“…A transaction represents an abstract view of a sequence of operations that are involved in the execution of an application. TM (originated from database systems) has been used in a number of applications such as e-commerce, m-commerce, and engineering applications [2,15]. We believe that TM is important for M-services, since protecting and managing the integrity of M-services' outcomes is essential.…”

“…However, we see that problematic. Accordingly, our paper proposes a relaxed set of transaction correctness criteria, called SACReD (Semantic Atomicity, Consistency, Resiliency, Durability) (previously developed in [15,16]) and a protocol for enforcing them, which it argues are more appropriate to the context-aware, more volatile, dynamic and open nature of M-services transactions. Unlike ACID criteria, SACReD do not impose isolation policy thus allowing transaction to be partially committed.…”

-with the ubiquity of handheld devices people can now access information and conduct online transactions virtually anywhere and anytime. In such flexible but less reliable environment transaction management technology is believed to provide service reliability and data consistency. Existing models developed for mobile transactions mainly focus on variation of conventional commit procedures and give little or no attention to the context-awareness which has become a crucial part of modern mobile applications. Given the high availability of context-aware services, mobile transactions should not only acquire required services but should also comply with the service context. This paper exploits the service-oriented computing technology and accordingly proposes a novel approach that manages transactions using the contextual information of mobile services. The proposed approach has several advantages. It manages transactions such that they adapt to the required service context as well as user's needs. It also ensures the reliability of transactions and also increases their resilience to failures.

SUMMARYMobile computing greatly facilitates the provision of mobile services using portable and handheld devices which are connected through wireless networks. A pre-requisite for the provision of an effective service is to ensure quality of service (QoS) during the concurrent execution of requests and system or network failures. This paper presents a new transaction management approach for the provision of mobile services which is based on advanced transaction models and fuzzy selection criteria. It employs a novel QoS consensus moderation approach in order to select preferred mobile services from among various alternatives, thus providing multiple pathways to the completion of mobile service transactions. Unlike traditional transaction management schemes, the proposed approach takes into account QoS attributes in the commit process of mobile service transactions. The proposed approach is implemented as a prototype tool and evaluated through a number of experiments. Experimental results show that the proposed approach effectively selects mobile services and significantly increases the throughput (i.e. commit rate) of mobile service transactions.

This paper presents an approach that uses policies to manage contextdriven transactional Web services. Context feeds policies with details on Web services like current status, which permits aligning the behavior of these Web services to the transactional properties they need to satisfy. Context refers here to any information on the interactions a Web service initiates with peers and external environment. Three types of transactional properties are used namely pivot, compensatable, and retriable. Each property satisfaction calls for a set of policies that are specified with a policy language like WSPL. This paper also presents the adaptation strategy that supports developing context-driven transactional Web services. A prototype that implements this strategy is discussed in the paper, too.
