Wireless mobile sensor network is a grown field in network communication, WSN devices are light weighted which quipped with processor, memory and communicate one to another through radio waves. Due to limited capacity of devices and network bandwidth the problem of congestion and collision occurs, while multiple senders want to communicate in same time. In the previous research authors are proposed mac and network based methodology to resolve the congestion and collision problem, but in recent utilization of WSN devices need some efficient technique to improve the network performance with collision and congestion free network. In this paper proposed a collaborative network and mac layer approach to provide efficient network communication and congestion notification status (CSMA/Cn). That CSMA/Cn method immediately notify to sender while congestion arises in established route, so that the sender sends the data through alternative path that handled by network layer protocol name is ad hoc on demand multipath distance vector routing. All those work simulated through network simulator-2 and compare the result of AOMDV-CSMA/Ca with AOMDV-CSMA/Cn in the network parameters as throughput, normal routing, data sends, receives and delay and found that proposed AOMDV-CSMA/Cn perform well in all aspect of defined network criteria
