EECPH: energy efficient cooperative communication protocol for heterogeneous wireless sensor networks

Abstract

Typically, the energy consumption is the major issue in Wireless Sensor Network (WSN), and from past several years various clustering routing protocols are proposed to extend the lifetime of WSN. Sensor nodes can sense and sensed data will be forward to the Base Station (BS) in a cooperative manner. Hence, to transmit the data to BS a high amount of energy is required. To overcome this problem, the clustering approach is the key technique to reduce energy consumption. In this paper, we present an Energy Efficient Cooperative Communication Protocol for Heterogeneous (EECPH) Wireless Sensor Networks. Firstly, Cluster Head (CH) can be chosen according to the node initial energy, hop count, and remaining energy. Secondly, the introduction of cooperative node selection can reduce the uneven distribution of clusters. Finally, different levels of energy nodes are introduced namely normal, advanced, and super nodes to enhance the energy efficiency in heterogeneous WSN. Simulation results shows, the EECPH protocol outperforms with reference to network throughput, energy efficiency, and the network lifetime over EARPC, and LEACH protocol.
