Throughput Improvement in Energy Efficient Heterogeneous Wireless Sensor Network

Abstract

AbstractDesigning an energy efficient scheme in Heterogeneous Wireless Sensor Network (HWSN) is a critical issue which degrades the network performance due to node failure. An Energy Efficient Clustering (EEC) algorithm is proposed by combining the rotation based clustering and energy saving scheme for avoiding the node failure and prolonging the network lifetime. In EEC, network is partitioned in to clusters and cluster head is selected on rotation based by considering the highest energy and residual energy of the sensor nodes. Other cluster members are accommodated in a cluster on the basis of Basic Cost Maximum flow (BCMF) so as to allow the cluster head for transmission. Carrier Sense Multiple Access (CSMA), a contention window based protocol is used at the MAC layer for detecting the collision and to provide channel access prioritization to HWSN of different traffic classes with reduction in End to End delay, energy consumption and improved throughput and Packet delivery ratio (PDR) and allowing the cluster head for transmission without depleting the energy. The simulation result presents that EEC is not only stable to broadcast the data to the destination in HWSN but also save energy of the nodes, thereby increasing the lifetime of the network. Simulation parameters of the proposed system such as Throughput, Energy, and Packet Delivery Ratio are obtained and compared with the existing system.KeywordsHWSNClusteringEECCSMAContention based protocolPDR
