Snehal Kole · 2014
Inexpensive wireless communication, computation and sensing is now need of the Wireless Sensor Network (WSN). Wireless sensor networks (WSNs) comprises large number of wireless sensor nodes which can sense and process data in the environment in a periodic manner. In WSN, as the sensor node depends on its internal battery power, energy efficiency and lifetime of sensors have become a key issue on the performance of wireless network. To make effective utilization of energy resources of a sensor node, communication protocols can be designed precisely. Clustering the sensor nodes is one of the effective techniques to achieve this goal. Low- Energy Adaptive Clustering Hierarchy (LEACH) - A cluster based routing algorithm was proposed as a solution for low power consumption. One of problems in the LEACH protocol is “Extra Transmissions”. The goal of our research is to optimize the energy consumption of wireless sensor network by introducing a novel and adaptive technique on the traditional clustering protocol of the wireless sensor network. In order to improve network performance, the Distance based LEACH algorithm is proposed where the improvement is done in cluster formation technique based on distance parameter. In cluster formation phase of modified LEACH distance of sensor node from cluster head plus distance of cluster head to base station is taken into account.
