一种新的基于双控制信道Ad Hoc网络媒体接入控制协议

A New MAC Protocol for Ad Hoc Network Based on Double Control Channel

提出了一种新的基于双控制信道的AdHoc网络媒体接入控制(MAC)协议。该协议在两个相互正交的子信道上交换RTS/CTS控制分组,解决了RTS丢失问题、死锁问题以及多信道隐藏终端问题,并提高了协议的空间复用度。实验结果表明,和已有的多信道的接入协议相比,在网络负载较重和节点密度较大的情况下,新协议提高了网络的吞吐量。

A new media access control protocol of Ad Hoc network based on a new double control channel is put forward in this paper. This protocol can exchange RTS/CTS control grouping in two interorthogonal sub-channel, and also it can resolve problems of the lost of RTS, deadlock and multiple channel hidden terminals, and enhance the space multiplexing. The result of experiment shows that compared with existing access protocol of multiple channel, the new protocol is able to increase the throughput of the network in the condition of heavier network loading and higher node density.
