Optimal Routing in Multi-sink Sensor Networks based on Fuzzy Comprehensive Evaluation

Abstract

This paper proposes a new routing protocol, namely Optimal Routing in Multi-sink Sensor Networks based on Fuzzy Comprehensive Evaluation (ORFCE). The protocol applies fuzzy comprehensive evaluation with selecting optimal routing in multi-sink sensor networks by considering three factors, the least residual energy in path, the least average link quality in path, and hop counts from sensor to sink. ORFCE is a multi-path, hierarchical, active and on-demand mixed, and QoS-guaranteed distributed routing protocol. By means of simulating in OMNeT++, the application of the ORFCE protocol will prolong the network lifetime enormously, enhance the packet delivery ratio greatly, and reduce the number of control messages largely.
