现有无线协作MAC协议算法很少综合考虑信道状态和节点能量等因素的速率自适应优化设计。针对这一问题,设计一种新的协作MAC协议方案,该方案融合随机线性网络编码,并为隐藏终端问题引入请求中继帧机制;还根据接收信号的强度自适应的选择随机值,以协作传输条件为判断依据,来选择中继节点,从而进一步提升网络性能。仿真结果表明,所提方案能够达到提升网络性能的目的。
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.
