Abstract


Wireless Mesh Network (Wireless Mesh Network, WMN) is a new type of high-capacity , high-speed distributed multi-hop wireless networks , widespread concern in recent years by various industries . Routing protocol as one of the key technologies to improve the network performance of WMN , has high research value . Papers WMN has been a DSR multipath routing protocol research and propose a QoS-based DSR multipath routing protocol . The agreement on the basis of the original DSR multi- path routing , the introduction of the constraint of the QoS parameters , selected from a number of non - related routing the preferred route , the rest of the route as an alternate route . Simulation results show that the agreement enables data transfer efficiency , end-to-end delay WMN the QoS performance has been largely improved . At the same time , the paper introduced the hierarchical Chord structure WMN, a load balancing method based on the hierarchy of the WMN . The network node tissue for hierarchical Chord structure , and load balancing solutions with migration logical link algorithm combined . Simulation results show that the ideal load balancing effect , at the same time can provide a reference for future studies based load balancing routing protocol , and has great practical value in WMN .
