Optimization of Energy by using IWD Algorithm in WSN

Abstract: WSN (Wireless Sensor networks) is one of important wide spread networks that are effective in recent years because of the involvement of the network in terms of electronics, communication and information technology in the single network. Energy efficiency is the most required quality in a sensor network as each node consumes some energy with each transmission over the network. Energy optimization is required to improve the lifetime of network. In this paper, PEGASIS routing protocol is presented to optimize the energy by implementing IWD (Intelligent Water Drop) algorithm. This proposed IWD algorithm optimize its routing criteria by selecting the shortest path so that the energy which is involved inside the network can be optimized and thus increases the lifetime of wireless sensor network. Experimental results show that by using PEGASIS and IWD, energy consumption, throughput and packet overhead can be optimized.
