Cooperative communications is one of the promising techniques to enhance the performance of wireless networks. The extent of performance improvement needs to be carefully investigated, especially for wireless sensor networks, due to the overhead and energy costs involved with cooperation and the dependency on energy consumption models. In this paper, the authors propose a cooperative medium access control protocol, COMAC that enables cooperation in a realistic scenario using 802.11g based radios and leverages cooperative communications by making use of the overheard packets from neighboring nodes of a sender node.
