Signal strength based service discovery (S3D) in mobile ad hoc networks

Service discovery is an important part of realization towards ubiquitous computing with self-configurable mobile ad hoc networks. However, it is faced by the challenge of network dynamics due to node mobility. In this paper, we propose a signal strength based service discovery framework in mobile ad hoc networks. Service discovery is carried out selectively along reliable links by monitoring the qualities of wireless connections to neighbor nodes. We show by simulation that, compared to non-selective distributed service discovery, our approach achieves higher service success ratio, less message overhead and shorter service discovery latency.
