摘要
本文研究了当前多种有效的多信道自组织网络信道分配和接入技术,提出一种结合CSMA和TDMA两种接入方式,能适用于宽带无线自组织网络的信道共享机制,并利用OPNET仿真工具构建模拟的自组织网络场景,对提出的网络协议进行了性能分析,为下一步研究工作打下了基础。
Wireless ad hoe networks are comprised of a number of wireless nodes which are connected to each other in a multi - hop manner. It has emerged as one of the promising solutions for next generation wireless networks because it could provide high - speed data rata, enlarge wireless service coverage area and reduce the network installation cost. The transfer rate of wireless links could be decreased by interference, so using multiple channels for data transfer is an efficient way to lessen link interference and improve the overall system throughput of wireless ad hoc networks. We survey and classify the current MAC protocols for multichannel operation in wireless ad hoc networks. This paper also discuss the issues in the design of multichannel protocols and architectures based on the CSMA and TDMA , We demonstrate the effectiveness of this design via OPNET simulations.
