Fault Tolerance and energy efficient protocol for cluster communication in sensor networks

This paper presents a clustering routing protocol for event-driven WSNs with Reduction of Reporting node in each cluster. We demonstrate that decreasing the number of reporting nodes in each cluster; increase the number of reports that need to be sent to the sink in order to achieve the energy efficient and desired information reliability. The algorithm also aims at even energy dissipation among the nodes in the network by alternating the possible routes to the Sink and autonomous selection of energy efficient cluster head. This helps to balance the load on sensor nodes while avoiding congested links at the same time. Moreover, the algorithm proposes using an energy efficient approach by choosing high energy values of a node stored in buffer table for each round. We discuss the implementation of our protocol, and present its performance evaluation through Network Simulator.
