| 摘 要： | 针对当前Ad Hoc网络中节能机制多为单跳环境设计,提出了一种适用于多跳环境的节能MAC协议DCF-PS.该方案基于这样一个思路:在调制方式不变的情况下以更低的速率发送RTS分组和CTS分组,能扩大正确解调RTS分组和CTS分组的区域,合理的选择调制速率就能实现干扰区域中的所有节点正确解调RTS分组或CTS分组,从而根据RTS或CTS中的NAV睡眠一段时间,降低能耗.结果表明DCF-PS能够大大降低系统的能耗,同时基本消除隐藏终端的影响,提高网络吞吐量.

| Abstract: | As the current power-saving mechanisms were mostly designed for single-hop Ad Hoc networks, a power-saving MAC protocol DCF-PS in multi-hop Ad Hoc networks is proposed. The idea on which the protocol bases is that to choose appropriate modulation rate could insure that all of the nodes in the interfered region modulate RTS/CTS packets correctly and sleep for a while according to NAV. Results show that DCF-PS has better performance on the energy efficiency and network throughput than 802.11 DCF. |
