Design and implementation of touch-link algorithm for reducing the link connection time in ZigBee

The Demand for wireless lighting is expected to increase in the residential environment, as well as building, gym, factories in these days. A large number of wireless lighting is controlled by a controller in these environments. We proposed an advanced touch-link algorithm to reduce delay time that occurs when connecting a lot of wireless lightings. The ZigBee switch and 128 ZigBee lightings are implemented. By measuring the time it takes to connect the 128 lightings was 70 ~ 120seconds. It takes 0.5 to 1 second to connect the one lighting. Also the proposed algorithm also improves reliability of link connection of ZigBee lighting.
