Cooperation Communication(CC) utilizes the antennas of idle nodes to create a virtual MIMO(multiple-input multiple-output) system.The CC can combat the fading in wireless links and achieve spatial diversity gains,which makes it a key technology for the next-generation wireless mobile networks.Nowadays,many researches focus on increasing the channel capacity,decreasing the energy consumption and outage probability by selecting appropriate cooperative nodes.New MAC(medium access control) mechanisms(cooperativ...
