Ileach- An Integrated Leach Routing Protocol for Elongating The Network Lifetime for WSN

Abstract

The Wireless Sensor Network (WSN) is composed of a collection of sensor nodes, which are small and energy constrained device. The efficient use of energy source in a sensor node is most desirable criteria for prolong the life time of wireless sensor network. So designing efficient routing for reducing energy consumption is the important factor. In this paper, we propose an effective version of LEACH routing protocol, ILEACH which will extend the performance of the system by extending the network lifetime by modifying the threshold equation for selecting the cluster head (CH) for every round of clustering. We experimentally showed that our proposed mechanism give better network performance in terms of lifetime and less amount of power consumption in the network. We also showed a situation of critical packet delivery and able to get less delay for critical packet delivery to the base station (BS) directly with a differential routing approach. We stated our future work for extending our research work. Keywords: Wireless Sensor Network, LEACH, ILEACH, energy efficiency, network delay
