Using Limited Flooding in On-Demand Distance Vector Junior for Reduction Power Consumption in ZigBee Networks

ZigBee network uses the simplified version of on-demand 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 network for finding the shortest path. It causes that high energy is consumed in the network. As a result, ZigBee nodes that are supplied by batteries will die early. Therefore, an AODVjr based on Limited Flooding (FLAODVjr) in the network 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.
