An Optimized Connectivity Scheme for Increasing the Join Ratio of Zigbee Network

Zigbee networks based on the IEEE802.15.4 standard are designed for wireless sensors and control networks with low-cost, low-power consumption and low-data rate. In some applications, Zigbee devices are randomly deployed and even though a device has a communication radius which can reach other joined nodes network, it still may be rejected to join the network, due to some network configuration parameters. And these devices become isolated devices. These isolated devices degrade the performance of the network. This paper proposes an optimized connectivity scheme. This paper decreases the isolated nodes and prolongs the network lifetime. Results show the performance enhancement in terms of join ratio of the Zigbee network.
