Performance analysis of congestion in Wireless Sensor Networks

Now a day large research is going on in Wireless Sensor Network (WSNs). WSN is collection of various sensor nodes and one destination as sink. These nodes sense the environment and transmit data to the designation sink. The main aim of wireless sensor network is data dissemination to the destination sink which must be reliable. All the nodes send data at a time, so congestion may happen and is the most important problem in WSNs. Congestion causes arbitrary dropping of packet and energy wastage. This paper describes the performance analysis of existing routing protocol in WSNs. Simulation result shows the suitability protocol for random topology in terms of packet delivery ratio, received packets, total drop packets, node density.
