Optimization of Energy in Wireless Sensor Cooperative Networks

In Wireless Sensor Network transmission policy, topology control, routing, and MAC protocols, can play a vital role in extending network lifetime. In cooperative networks, transmitting and receiving nodes recruit, neighboring nodes to assist in communication. Due to the spatial correlation between sensor nodes, it may not be necessary for every sensor node to transmit its data. This paper shows how the spatial correlation can be utilized on the Medium Access Control layer. Based on the type of packets, packets can be classified as network transmission packets or route thru packets and the priority of transmission can be worked out. The authors then propose a cooperative communication protocol for establishment of cooperative transmission of data.
