关于无线Mesh网络多通道MAC协议的改进
An Improved Multi-Channel MAC Protocol for Wireless Mesh Networks
摘要
Abstract
The current IEEE 802.11 protocol is aimed at single Access Point(AP)environments and many problems related to the wireless meshed interconnection of APs and Mobile Terminals(MTs)remain to be solved.Some proposed solutions to build such mesh architectures are based on single-channel ad-hoc oriented schemes in which IEEE 802.1 1 protocol has been modified.The main problem with this type of schemes,however,lies in the very low performance of the single-channel architecture itself.An improved multi-channel mesh architecture is presented which works using a Distributed Coordination Function(DCF)-based technique for interconnecting APs.The simulations results obtained in OPNET 8.1 show a good performance of our pro-posed scheme in terms of throughput and channel utility.关键词
