摘要
提出了一种新的基于单信道的Ad Hoc网络功率控制协议,通过2个节点间控制包的交换来计算数据包的发送功率,采取时分复用的方式将同一节点附近的控制包和数据包分开传输,避免了冲突,减少了能量消耗。仿真结果显示:这种协议在提高网络容量、节约能量方面都取得了很好的效果。
The power control algorithms for Ad Hoc network are summarized, and a new single channel power control protocol is proposed. The power levels for data packet are calculated through the RTS/CTS control packet exchange of two nodes. The data packet and control packet are transmitted separately by the means of time division multiplex. The method can avoid collision and reduce the energy expense. The simulation also shows this protocol can obtain significant throughput and energy gains.
