In the field of wireless communication, zigbee is a latest technology in wireless network based on IEEE 802.15.4 standard. On IEEE 802.15.4 standard based zigbee network uses low power sensor nodes to ensure reliable, process, collect, and store the data. The sensor nodes have low cost, smaller in memory size and used in lower coverage area first two layers based on IEEE 802.15.4 standard are PHY and MAC layer. Routing protocols are divided in two categories that are reactive protocol and proactive protocol. AODV routing protocol comes under reactive protocol. It creates route between source and destination when needed. When source node has data to transmit to the destination node then it will create RREQ (route request message) and send to all neighbors in the network, when the destination node found or neighbor node found the route to destination then they will generate a RREP (route reply message) and forward back to source node. After the creation of route between source node and destination node they can exchange the data.
