A MAC based On-Demand Converged Broadcast Scheme for Congestion Avoidance in Wireless Sensor Networks

Abstract

Wireless Sensor Network (WSN) is an integrated collection of independent sensor devices that gather information from the environment, manipulate on them and relay the same to a common node or base station. There are several factors that affect the sensor performance that serves as a major design and deployment issue consideration at the time of designing these networks. Congestion in these networks leads to improper resource utilization and retard in performance enhancement. We address the problem of earlier energy drain due to improper congestion management caused by broadcast storm. MAC based On-demand Converged Broadcast (M-OCB) is a neighbor aware opportunistic technique to minimize link flooding in WSN so as to minimize congestion and early energy drain. This method bridges the gap between energy and congestion by distinguishing neighbor selection and broadcast process as distinct integrated approach. The proposed technique is analyzed using simulations. The simulation results confirm that the proposed technique performs better on throughput, delay, energy, drop and congestion ratio.
