Research on Energy Sensing Based Fault-Tolerant Distributed Routing Mechanism for Wireless Sensor Network

For the serious impact of network fault caused by the uneven energy consumption of sensor nodes, hardware failure, and attacker intrusion on data transmission, an energy sensing-based fault-tolerant distributed routing (ESFDR) mechanism for a wireless sensor network is proposed in this paper. ESFDR is composed of three interrelated algorithms, namely the distributed energy sensing clustering algorithm for the cluster head selection in the wireless sensor network, the route selection routing algorithm (DRSA) which helps the cluster head to obtain k-disjoint routes to the base station, and the novel routing maintenance strategy for route restoration. The efficient transmission of data can be achieved by the combination of these three algorithms. Performance analysis and simulation results show that the proposed routing mechanism can improve the QoS of the wireless sensor network and reduce the impact of network fault effectively.
