Research On Multipath Routing Qos-Based In Wireless MESH Network

Wireless Mesh Networks is a new high-capacity, high-speed broadband wireless distributed network. View of the stability and real-time can not meet the demand of multimedia applications, in this paper, we will introduce Qos security technology and multipath ideas to the Ad hoc on-demand distance vector routing protocol (AODV). First, we can add the bandwidth and latency to the original route request packets to reflect the demand of Qos in the source node, calculating the available bandwidth and end to end delay during the routing discovery process, looking for Qos parameters as the measure of multipath, and then the Qos-based multipath AODV routing protocol algorithm is proposed, at last we use the NS-2 simulation software to show that the improved routing effectively enhanced the packet delivery rate, reduced the delay, ensured reliable packet delivery.
