Design And Implementation Of Wireless Mesh Network Based On IEEE 802.11s

In the past few years,WLAN netowrking technology is getting more and more restrict because of the limited coverage and simple star-shaped topology.And it needs advanced development by supporting open topology and flexable networking technology,which means also the promising part of wireless networks.So there is no doublt that wireless Mesh network is working as a key technology for the next-generation wireless network due to its intrinsical dynamically self-organised and self-configured features,especially on some emergency and remote medical occasions which have an urgent requirement on fast networking technology.This master thesis focuses much on the study of networking technology based on IEEE 802.11s standard and the main work of thesis is listed as follows:The first study will be focused on two typical application scenarios of wireless mesh networks:low-power hign-efficient scenario and low-latency high-reliability scenario.Firstly,two novel routing algorithms are proposed respectively according to the analysis on requirements of the above-mentioned two scenarios.After the verification by plenty of simulation,the pwer-efficient routing algorithm can bring prolonged network sustainability and improved power efficiency performance,and the other can reduce the end-to-end lantency of the wireless network link.The second study is based on the embeded cotex-A8 core-board.This article describes the proposal Mesh notworking hardware and software designment,and put forward a novel set of flexable networking solution which contains three parts:efficient IP solution,two-factor authentication and wireless Mesh management architecture.Besides,sufficient tests are conducted for validation based on the testbed.The article compares the simulation result with testbed’s and verifies the reliability of the proposal networking solution.Finally,the main work of the beforementioned two aspects is summarized,and future directions are proposed.
