ZigBee work uses the simplified version of ondemand distance vector (AODV) routing which is named AODV junior (AODVjr). There are three main differences between it and AODV. It does not have sequence number of destination and eliminates the sending error packet when a node crashes. The third difference is preventing form sending Hello messages periodically for detecting the active nodes and use connect message that it sends by destination node. The other features are the same in both of them. One of them is the broadcasting of Route Request (RREQ) in the work for finding the shortest path. It causes that high energy is consumed in the work. As a result, ZigBee nodes that are supplied by batteries will die early. Therefore, an AODVjr based on Limited Flooding (FLAODVjr) in the work is suggested in this paper. This approach uses the information of tree routing algorithm for limiting the broadcasting of RREQ packets. The results of simulations prove the improvement of using this method.

It is used in a variety ofapplications due to these features. It is one of the best choices for many works that they do not need to high data and have restrictions in the accessing in
