On the basis of Ad hoc On-Demand Distance Vector Routing（AODV） protocol and in view of the defects of poor routing performance arising from unitary routing criterion for traditional AODV Wireless Mesh Networks（WMN）

this paper designs a novel Improved AQDV（IAODV） by employing a cross-layer design method.Furthermore

it extracts such factors affecting the link quality as the current node load and link delivery rate by the cross-layer operation mechanism in the route calculation process and designs a rational routing decision function in combination with the routing hops.Theoretical analysis and NS2 simulation results prove that this route optimization mechanism improves the throughput

reduces the network delay and achieves load balanced routing.
