ZigBee network 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 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.Keywords: ZigBee, Limited Flooding, AODVjr, Power Consumption.1 Introduction ZigBee network is a wireless network technology which provides low data rate, low power consumption, low cost and reliable munications. It is used in a variety ofapplications due to these features. It is one of the best choices for many networks that they do not need to high data and have restrictions in the accessing in power supplies such as automation and monitoring applications [1].The Physical (PHY) and Medium Access Control (MAC) layers of ZigBee are based on IEEE [2]. It is developed by ZigBee Alliance [3]. This technology operates in unlicensed frequency range of 868MHz, 915MHz and with data rate 20250kbps and also has a coverage range of 10100m [2].The nodes are divided into two types that include Full Function Device (FFD) and
