An Innovative Scheme for Increasing Connectivity in ZigBee Networks
Chia‐Ming Wu, Ruay-Shiung Chang, Pu-I Lee · 2011
ZigBee networks based on the IEEE 802.15.4 standard are designed for wireless sensor and control networks with low cost, low power consumption, and low data rate. To join in a ZigBee network with the tree topology, the hardware requirement of a device is simple and low threshold. However, a device may become an isolated node due to constraints of configuration parameters in the ZigBee network. To decrease isolated nodes, we propose an approach called Enhanced Connectivity Scheme for the ZigBee network. This scheme can efficiently reconstruct parts of the network to let more devices join and hence increase the join ratio. Our method can efficiently improve the connectivity of ZigBee networks. The experimental results show that Enhanced Connectivity Scheme has high performance. We provide an innovative solution to increase connectivity of ZigBee networks.
