A NOVEL METHOD FOR IMPROVING THE THROUGHPUT IN HIGH DATA RATE WSNS

Abstract: Energy efficiency and throughput are main concerns while designing routing protocols for wireless sensor networks (WSNs). However, most of the existing schemes are either improving energy efficiency or improving throughput. Low Energy Adaptive Clustering Hierarchy (LEACH) is one of the major hierarchical routing protocols for WSNs to minimize the energy consumption. In order to minimize the energy consumption, in this work we have introduced access points in the network in between cluster head and base station. The QoS parameters such as throughput, packet delivery ratio, delay and energy consumption are metrics used to measure the performance of energy efficient reliable routing protocol and proposed three tier architecture. Simulation results show that three tier architecture outperforms the energy efficient reliable routing protocol and m-leach protocol.
