Congestion Avoidance and Control Mechanism for Multi-paths Routing in WSN

For solving the issue of congestion in WSN (wireless sensor network), proposed a congestion avoidance and control mechanism for multiple paths routing protocol (MR-CACM), which integrates fairness, status of congestion and level of energy. Consequently the network can avoid congestion by assigning traffic to different paths. When congestion is occurred, it can help to detect congestion by using the values of transmitting capacity and alleviate congestion by reassigning traffic. The results of simulations validate MR-CACM can avoid and alleviate congestion, and has reasonable effects of reliability, low energy consumption and high throughout.
