Abstract: | The existing wireless cooperative MAC protocols rarely consider the impact of channel condition and node energy consumption.To this issue,a new wireless cooperative MAC protocol was proposed,which used the random linear network coding,and introduced a mechanism of request relay frame to solve the hidden terminal problem.Specifically,the proposed method adaptively adjusted the node rate according to RSSI,and determined the relay node based on the requirements of cooperative transmission.The simulation results show that the network performance can be improved through deploying the proposed protocol. |
