Dual hop multicast ping method for node failure detection in ZigBee loop network

This paper reviews node failure detection method in ZigBee loop network. ZigBee network was popularly used for low power and low cost implementation of wireless data transmission. Node failure detection is needed in order to maintain the network reliability. Common node failure detection methods are based on ZigBee mesh networking capability. But in many application areas which have simple loop topology, ZigBee will not get much benefit from its mesh networking capability. We propose a multicast ping with dual hop grouping for failure detection and protection in ZigBee loop network, in order to give simple node management, efficient processing resource, and uniform firmware implementation. This method has been simulated in Network Simulator (NS2) tools. The result has validated that dual hop multicast ping method can be used in ZigBee loop network for accurate node failure detection. The simulation shows that the implementation of method also increases average end-to-end delay from 0.06 second to 0.08 second as trade off to network performance.
