SERP: A Simple Energy-Hops-Based Routing Protocol in WSNs

When we design a routing protocol for WSNs, it is necessary to found an energy control mechanism to reduce the overhead of wireless communications. Considered that WSN systems need a simple routing protocol in practical applications, we designed a simple Energy-hops-based routing protocol (SERP) in this paper which can be used in most WSN systems with low communication overhead and complexity. We analyzed the performance of the SERP, furthermore we run it in a real WSN experimental system consist by GAINS3 sensor nodes. The experiment result confirmed that the SERP is highly effective by which the WSN system energy can be balance while the working lifetime can be increased.
