Energy-Efficient Cluster-Based Service Discovery in Wireless Sensor Networks

Abstract

We propose an energy-efficient service discovery protocol for wireless sensor networks. Our solution exploits a cluster overlay, where the clusterhead nodes form a distributed service registry. A service lookup results in visiting only the clusterhead nodes. We aim for minimizing the communication costs during discovery of services and maintenance of a functional distributed service registry. We compare theoretically and by simulation the impact of the chosen clustering algorithm on the service discovery protocol
