Energy Efficient Cross Layer Design Protocols using Distributed Method of Information sharing in Wireless Sensor Networks- A review

Abstract

In Wireless Sensor Network nodes are densely deployed and are prone to failure and the topology of sensor network changes very frequently. Sensor nodes are tiny devices limited in power, computation capacity, memory, sensing range and mobility. The major factors responsible for energy consumption in WSN‟s are idle listing, collision, overhearing, overhead, congestion and unnecessary high transmission range. In this paper we reviewed the various cross layer designs using distributed method of information sharing among the layers and came to the conclusion as MR (MAC-ROUTING) is the best approach to design easily with good results in various parameters of network throughput, end to end delay, energy consumption, overhead, packet loss and residual energy compared to other cross layer approaches. Here we also observed that MAC layer plays a vital role in minimizes the energy consumption in various types of cross layer approaches.
