A Lifetime Aware Approach to Service Selection in Mobile Ad Hoc Networks

Service oriented architecture is expected to be implemented as an effective way for mobile ad hoc communications and collaboration in ubiquitous computing environments. Much effort has been devoted on the service discovery protocols, while fewer works focus on the problem of service selection. The approaches proposed in previous works of service selection are mostly hop based approaches which aim at reducing the average response time. However the network lifetime which measures the durability of the network is also of great importance and should be paid more attention. In this paper, we first present a definition of the network lifetime from the aspect of the service oriented architecture. Then, a heuristic approach to service selection which focuses on optimizing the network lifetime is proposed. Experiments results prove the approach can significantly prolong the network lifetime while at the same time achieve comparably short average response time.
