【 摘 要 】

Due to the dynamic infrastructure in Mobile Ad-hoc Networks (MANET), supporting a reliable and timelyservice access is one of the main requirements of applications deployed over MANETs. In this paper, areliability-aware service selection scheme is proposed in which a client node collects and ranks theavailable service providers based on their estimated response time and reliability. However, estimating thereliability of a service provider in MANET is a challenging issue because it is strongly dependent on thecurrent conditions of the network (dynamic or stable). To estimate the network state based on the localobservations, Hidden Markov Model (HMM) is applied prior to the service selection.. The experimentalresults show that by using our method, not only the unreliable service providers are filtered but also,comparing to the existing service selection methods, lower violations of the client response timerequirements (defined in the client SLA) are observed.
