Abstract

Congestion control has a great importance in wireless sensor network (WSN), where efficient application of congestion control mechanisms can prolong the network lifetime. Thus, proper examination is needed to improve more refine way to address the congestion occurrence and resolution. While designing congestion control techniques, the maximum output can be achieved by efficient utilization of required resources within WSN. From last few years several approaches have been brought in, that consist of routing protocols which provide support with congestion control, congestion prevention, and reliable data routing. In old schemes the topology reset and extent traffic drop take place because sink node executes the congestion avoidance. Therefore, node level congestion avoidance, detection, congestion preventing, and resolution mechanisms have been proposed during past few years. Our paper provides a brief overview and performance comparison of centralized and distributed congestion control algorithms in WSN.

Summary

INTRODUCTION

Wireless sensor network (WSN) consists of very small wireless devices deployed in a huge geographical area to examine the surrounding environment. For network level, the cause of node failure is due to the changes in path and topology that must be treated properly to reduce the relative packet loss and energy exhaustion [8]. Congestion should be managed to prevent the data loss by fair distribution of the bandwidth for all the network nodes especially for the distant nodes [8]. The distribution of traffic loads at congested and substitute paths are not handled properly. This survey paper provides a brief overview on congestion control mechanisms by graphically illustrating the working of some of the congestion control algorithms. This paper highlights the shortcomings of the existing congestion control mechanisms
