found that the improved program can effectively reduce the delay and avoid conflict.

AODVjr algorithm bases on the fastest path routing by simplifying the routing discovery
and routing table,delete the Hello message in order to achieve the purpose of reducing
control overhcad.To further achieve the low control overhcad,the paper uses the ZBR

algorithm.The ZBR is a compromise of the two algorithms,not only has the ability of
routing optimization of the AODVjr,but also the advantage of the Cluster-Tree such as
simple and no initial delay.The simulation shows that the improved algorithm can better
meet the design requirements,with the feasibility of achieving.
