In order to minimize such problems as breakdown

long communication recovery time and large network load occurred when the destination node in the classical Ad hoc On-Demand Distance Vector（AODV）routing protocol departs from the node originally in direct communication as it moves randomly within the established scope covered by the routing link signals

this article studies the implementation of fast routing repair by activating the communication handover from the intermediate node to the destination node using the AODV Hello messages

and obtains an improved routing protocol

AODV-L.Simulation results show that this AODV-L protocol reduces the network load and shortens the routing repair time

more suitable for networks that the destination node randomly moves within the scope covered by the routing link signals and that the internode communication has higher real-time performance.
