REVIEW ON CONGESTION CONTROL TECHNIQUES IN WIRELESS SENSOR NETWORKS

Abstract

Congestion is an very important issue in communication network. Congestion in wireless sensor network
causes loss of packets , delay , degradation in utilization ratio , throughput and efficiency. Unpredictable traffic load,
many-to-one , one-to-one communication nature and limited bandwidth occupancy are among major reasons that can
cause congestion in such networks. Therefore, in order to enhance the network quality of service (QoS), developing a
solution for congestion estimation and control is imperative. In this paper, we review a different methods for congestion
control and propose a new technique to control the congestion very effectively. The proposed system is able to detect
congestion and control the congestion and make system more efficient and achieve a maximum packet delivery ratio. As
a result, the proposed approach provides a better quality of service.
