Abstract


Wireless Mesh Network (WMN) has emerged as a key technology of self-organization distributed wireless network, which is becoming a new solution to the "Last Mile" issue. As a new type of network structure, it has been contained in much standard process, such as IEEE 806.15\802.16m\802.11s. By of the structure trait of network itself and complexity of the wireless transmission environment, the reliability of data transmission has been influenced seriously because of the link change and data conflict. How to choose a sensible wireless route path to guarantee the QoS of transmission is a critical issue in Mesh route protocol research. Aimed at research of route protocol in WMN that is to guarantee service flow with different priority, this thesis studies the existing wireless network routing protocol, and implement a multi-path routing protocol.Firstly, the thesis studies the structure of WMN and the process of Mesh standard development, analyzing the key technology details; secondly, in order to research the relationship with the structure of WMN, the thesis studies the existing wireless routing protocol, include the advantages and disadvantages; thirdly, a multi-path routing algorithm is designed to meet QoS assurance of different service type, protect the high-grade priority services as far as possible to care the transaction capacity of low-grade ones; finally, the thesis gives the test of the routing algorithm and simulation results. Simulation results shows that, the designed multi-path routing algorithm can meet the QoS requirements of different priority service type in a certain extent.
