Service oriented architecture is expected to be implemented in mobile ad hoc network. The execution of composite service is an important research issue in this area. Most previous works focus on the centralized architecture which assumes the existence of a central scheduler. In this paper, we propose the decentralized service execution architecture which do not need a central node to take responsibility...
Service is accepted as an effective way for mobile nodespsila communication and collaboration in MANETs. Many efforts have been spent on service discovery and selection, but few works study reliable service discovery and selection. Furthermore, since the dynamic nature of MANETs and limited energy of nodes lead to a high probability of service failure in MANETs, it is necessary to select a reliable...
Service composition is considered an efficient way to complete complex task in mobile ad hoc networks. Most previous works focusing on composite service execution are based on the centralized architecture while the decentralized architecture can avoid the large amount of round-trip messages thus significantly reduces the transmitting costs in the network. However, to implement the decentralized service...
There has been great interest in service composition to exploit resources of distributed nodes in mobile ad hoc networks. During composite service execution, the execution path for composite service is very important because of its significant influence on network overhead and the percentage of failure. In this paper, we study the execution path selection problem, which focuses on selecting a short...
Service composition is a hot research topic in Web Service and a particularly important way to exhibit the advantages of nodes' cooperation in MANETs. Service execution is critical for service composition in MANETs, but there is less research focusing on this topic. In this paper, we explore the problem of service execution path selection approach for composite service in MANETs. Then we propose a...
There has been recent interest in service composition over MANETs, to exploit heterogeneous resources of distributed nodes. Such composition service executions, however, suffer from the characters of frequent link failures and dynamic topology of MANETs. In this paper, we study the recovery problem of decentralized composite service execution over MANETs. We propose four strategies based on three...
