Novel Approaches for increasing Energy Efficiency in Wireless Sensor Network

Abstract

Wireless sensor network is made up of very tiny motes called as sensor nodes and a fixed or mobile base station. For making the network reliable many routing algorithms are proposed. The important features for making the system reliable are flexibility, ability of self organizing and to be energy efficient. Due to the presence of sensor nodes in harsh environment it is not possible to provide unlimited power source so, energy efficiency is a major issues in WSN. Multi-objective Approach for Energy Efficiency and Multiobjective Cluster Based Approach protocols are proposed to increase life cycle of network. In these protocols the cost of each link is calculated and assign to each path and Minimum spanning tree are formed by using greedy approach. These protocols require multiple objectives such as residual energy, transmission energy and delay for finding the best and shortest routing path to base station. The proposed protocol shows better results as compared with LEACH protocol.
