Reliable Communication Framework for Congestion Mitigation in Wireless Sensor Network Using Multiple Sinks : A Novel Approach

The proposed system exhibit the issues of congestion in WSN which usually takes place when the quantity of the sensor motes reporting data maximizes towards sink mote. This phenomenon will cause minimization of optimal throughput and loss of valuable data. The proposed system highlights a novel approach for mitigating the ill-effects of traffic congestion in the area of wireless sensor network. The proposed system has also introduced the concept of multiple sink to mitigate the congestion issue. Designed in NS2, the proposed system considers multiple sinks, which are facilitated for the traffic distribution among all the other sinks in order to mitigate congestion. While the majority of the prior research has aimed for congestion detection and avoidance, this work will more focus on congestion mitigation. The experimental framework is designed using IEEE 802.15.4 sensor networks and conducts various iterations of the experiments for validating the efficiency of the protocols used. The result shows that with continuous triggering of the sensor motes will lead to traffic congestion. Keywords-component; Traffic Congestion, Congestion, Wireless Sensor Network, Multiple Sink
