An Energy Balanced Clustering Routing Protocol for WSN
Energy conservation is one of the research hotspots in WSN, while routing protocols have direct impact on energy consumption.On the basis of analyzing the existing clustering multi-hop routing protocols, a cluster-based routing protocol (EBCRP)that considers multiple factors to balance energy consumption is proposed.In EBCRP,relay cluster heads are selected by considering the distance and direction to itself, experience factor is multiplied to make that the probability being a cluster head changes with the distance from the node to the Sink by negative expo nential function;relay cluster heads wait for a certain time to facilitate data fusion ,which is inversely proportional to the distance from the Sink to itself; in addition, the rotation cycle is discussed by simulation, and an optimal cycle is determined.The simulation results show that EBCRP can enable WSN that the first node death postponed, more balanced energy consumption, longer lifetime.
