An improved rejoin procedure in ZigBee networks
Yuanxin Jiang, Doo-Hyun Kim, Sung Ho Cho · 2009
In this paper, we propose a method to save energy consumption for the rejoin procedure of ZigBee networks. By skipping the active scan process, a rejoining node and its neighbors are able to save a large amount of energy. In addition, the rejoining node chooses the suitable potential parent by reserving and utilizing original neighbor table. This method is capable of reducing the number of rejoin request command frames, thus reducing the network traffic to some extent. Simulation results demonstrate that the proposed rejoin procedure contributes to more effective and efficient energy consumption.
