摘要

本文提出一种工作在单信道、单发射器和单发射功率模式下的并发传输MAC协议.该协议在控制报文(RTS/CTS)和数据报文(DADA/ACK)之间插入附加控制时隙

以便相邻节点有机会交换自己的控制报文.为了保证并发传输的可靠性

协议在控制报文中包含了冲突避免信息

邻居节点根据这些信息判断自己的传输能否在不影响已有传输的情况下并发进行.模拟结果显示

与IEEE 802.11相比

CTMAC协议在网络中存在并发可能时

使系统吞吐量得到很大提高.

Abstract

We present a novel concurrent transmission MAC protocol for MANETs which enjoys the simple design of single-channel

single-transceiver and single-transmission power architecture.The proposed protocol inserts additional control gap between the transmission of control packets (RTS/CTS) and DATA packet

which allows a serious of RTS/CTS exchanges to take place before the possible multiple

concurrent data transmissions.To assure these concurrent data transmissions finishing correctly

the collision avoidance information is included in control packets.These information are used by neighboring nodes to determine whether begin their transmissions or not

as in traditional transmission power control schemes.Simulation results show that

compared with IEEE 802.11

significant throughput gain can be obtained by the proposed protocol.
