Abstract: This paper reviews the studies of ZigBee wireless network and makes a simulation analysis to show that the performance of ZigBee in a non-beacon-enable mode is better than that in a beacon-enable mode. In the beacon-enable mode, if there are many nodes transmitting simultaneously or there is a heavy load, a large number of collisions and retransmissions occur, which sharply reduces the network throughput. On the other hand, in the non-beacon-enable mode, there are less collisions and retransmissions, which leads to a better performance. The possible applications of ZigBee in aerospace with respects to multiple access and networking, coexistence and connectivity, emergency communication and dynamic configuration, etc., are discussed
