Abstract: ZigBee,a wireless local area network(WPAN)ficld technical standard based on IEEE802. 15. 4,with the advantages of low power consumption, easy extensibility and giant network capacity is increasingly popular. Its unique Mesh network has very strong self-healing ability with ad hoc network as node failure. The powerful self-hea-ling property of the Zigl3ec network was verified through simulating the dynamic routing fault scenarios in OPNEIT.

Key words: Zigl3ee, OPNET, Mesh network, Self-healing
