The low cost, low power, low complexity Zigbee defined in IEEE standard 802.15.4 for low rate WPAN's upon MAC and physical layer. The objective is to make possible of incalculable process among next generation devices with small transmitters and agree to communicate between devices with central PAN coordinator. Thus zigbee desires efficient routing protocol to deal with lowest amount of energy expenses and highest network life time. In this paper zigbee provides cross layer network protection and application service carried out with hierarchical cluster tree formation.
