摘要：Congestion in WSN is an important issue. Congestion occurs at the transport layer of the OSI model & is caused by buffer overflow because each node in WSN limited buffer space, energy and has limited resources. In WSN when the data travels from Source to Sink it has to pass through many intermediate nodes. Due to the event driven nature of WSN it leads to unpredictable network load as a result in congestion may occur at the nodes (i.e. intermediate nodes) which receive more data than the can forward and cause packet losses. The time during when intermediate nodes send WM to source to describe the congestion status will result in large amount of packet loss. This motivates the need of Load balancing at intermediate nodes. Our proposed work describes the multipath routing protocol which plays an important role in utilizing the available free spaces of the neighbored nodes and free routing paths to accommodate the load of Congestion Affected Node’s. In our work we also study the congestion symptoms such as packet losses, end to end delay and network load. The simulation the results shows that improved in the efficiency of the network by decreasing end to end delay and packet delivery fraction among the neighbored nodes.
