Effect of node density on congestion in WSN

Wireless Sensor Network (WSN) is gaining more popularity as it has wide application range. WSN is more cost effective for monitoring the different aspects of environment and industries. There is a matter of concern as WSN has inadequate resources such as computational power and energy constraint. Congestion is one critical subject which has drawn attention of many researchers. Congestion results into reduced network performance and also drains the battery of the node, which is a limited resource in WSN. So congestion must be reduced to improve Quality of Service (QoS) and lifespan of a network. In this paper we have shown the results for different QoS parameters by varying node density.
