Abstract: Wireless Sensor Network is a collection of sensor nodes. These nodes are to able sense the surrounding environment and based on changes in environment sends data to destination which is called as Sink in sensor networks. When any event occur each sensor node try to disseminate data to sink. Due this congestion becomes the primary problem of network which must be solved, the retransmission of data packet also increased. Due to congestion the other quality of service parameters (like reliability, throughput) gets decreased. There are two techniques by which congestion can be reduced which are: either by reducing the data sending rate of source or by providing extra resources. Reducing data sending rate will decreases the network throughput. In this paper we proposed the multiple sink mechanism in which sensor nodes are able to deliver data to multiple sink in the network. Simulation result shows that proposed congestion control mechanism improve the packet delivery ratio, reliability, throughput of the network and also reduces the packet loss ratio which reduces the number of retransmission, saves the energy of sensor node . This will improve the network lifetime. It will also able to handle the “Black Hole Problem” in the wireless sensor network.
