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. Keywords: ZigBee, Limited Flooding, AODVjr, Power Consumption. 1 Introduction ZigBee work is a wireless work 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 works 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 Reduced Function Device (RFD). A FFD node can act as a coordinator, router and enddevice. In fact, it can form a work and specify address to joint nodes, if it acts as a coordinator. Also, it enables to route the packets and plays the role of enddevice, namely, send its information to parent node. Another type of node, RFD, can just be enddevice in the work. From topological point of view, ZigBee has three topologies including star, tree and mesh that they are shown in figure 1. In the star topology, there are a coordinator and several other nodes which are connected to it by a hop. Tree is constituted based on parentschild relationships. There are a coordinator as a root of tree and other nodes that join as child to it. If a children node is a router, itcan accept some child under certain circumstances. The last topology is mesh. This topology has a coordinator and some routers and enddevices. The FFD nodes can municate with others, if they are in the coverage range of together. Thereby, there are maybe some paths between source and destination [3]. For finding shortest path, ZigBee uses routing algorith
