Improvement on LEACH Protocol in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) have great potential to support several important wireless applications, including real-time multimedia communication, medical applications, surveillance using sensor networks, industrial applications, military surveillance and home networking applications. But there are two challenging issues (i) communication bandwidth and (ii) energy are very important to design wireless and mobile systems because these are very much limited in network environment. Therefore it requires intelligent communication and design techniques to increase bandwidth as well as energy efficient protocol. The most efficient routing protocol LEACH (Lower Energy Adaptive Clustering Hierarchy) in wireless sensor networks (WSNs) has been incorporated by Heinzelman et.al. LEACH uses the concept of dynamic clustering when sensor nodes are deploying randomly where number of cluster impact on the network. This paper describes the network quality that depends on different characteristics of data transmission as a Modification on LEACH protocol. In this paper, we discussed and explain the comparison of magnitude, phase, phase delay, group delay, amplitude of broadcasting and energy consumption respectively.
