ZigBee is based on the IEEE 802.15.4 standard and was designed to be used in wireless control and sensor networking. ZigBee provides self-organized, multi-hop and reliable networking facility with long battery lifetime. ZigBee standards have been developed to provide simple, low cost and battery efficient wireless devices. Mobility is part of ZigBee vision and it is difficult to provide to/from connections to mobile end-devices. Due to movement of end-devices, data delivery failures occur in ZigBee wireless network.
