摘要
基于无线自组网中多址接入协议对网络性能有着极其重要影响的特点,重点研究了无线自组网多址接入协议层信道接入技术,分析了现有的主要的无线自组网多址接入协议.基于CSMA/CA信道接入协议,提出了一种改进的中小型无线自组网多址接入协议.改进的无线自组网多址协议采用控制信道和接入信道分离设计,改善了网络的信道利用率和传输的可靠性.
Multiple-access interference constitutes a major cause for performance degradation in ad hoc networks. The objective of this paper is to study more efficient medium access control protocol （MAC） for ad hoc networks. Based on the analysis of the popular representative MAC protocols, a slotted MAC protocol based on multi-channel mechanism is proposed. With separated designs for control channel and access channel, this MAC protocol mechanism improves the channel utilization and the data transport reliability.
