Mobile ad-hoc networks are constructed without the infrastructure. All the MANET operations are planned with the consideration of the energy and bandwidth limitations. Cooperative communication utilizes nearby terminals to relay the overhearing information to achieve the diversity gains and improve the transmitting efficiency in wireless networks. Cooperative Medium Access Control (CMAC) protocol is constructed to achieve the medium access interactions with relay model. We propose DEL-CMAC that focuses on the network lifetime extension, which is a less explored aspect in the related work. By considering the overheads and interference due to cooperation, as well as the energy consumption on both transceiver circuitry and transmit amplifier, DEL CMAC can significantly prolong the network lifetime.A distributed energy-aware location-based best relay selection strategy is incorporated, which is more reasonable for MANETs comparing with the existing schemes based on channel condition.
