Abstract:
Energy consumption is a major issue in wireless sensor networks (WSNs). Many researchers have the focus to reduce energy consumption. The network lifetime of WSNs is affected by energy consumption of sensor nodes. For typical applications such as structure monitoring, border surveillance, embedded in the outer surface of a pipeline, and mounted along the supporting structure of a bridge, the sensor node energy efficiency is an important issue. In this paper, we present an energy efficient multi-hop routing protocol using hybrid optimization algorithm (E2MR-HOA) for WSNs. The proposed routing protocol consist of two algorithms i.e. hybrid optimization algorithm. We present modified chemical reaction optimization (MCRO) algorithm to form clusters and select cluster head (CH) among the cluster members. Then the modified bacterial forging search (MBFS) algorithm used to compute reliable route between sources to destination. The proposed E2MR-HOA protocol is evaluated using NS2 simulations. The simulation result shows that the proposed routing protocol provides significant energy efficiency with network lifetime over the existing routing protocols.
