Monitoring and controlling packets transmission improvement based on the physical depth in the ZigBee networks

Abstract

ZigBee provides a simple and reliable solution for the low cost networks. However, the current routing algorithms cannot fully satisfy the energy consumption issue. In this paper, we propose a minimum physical distance (MPD) broadcasting algorithm the transmission of the monitoring and command packets which are from or to the ZC. The physical depth is introduced to indicate the least hops to the ZC, and the transmission paths are decided based on the neighbour table information. The simulation results show that the MPD could improve the performance of the monitoring and controlling packets transmission by providing shorter paths lower delay.
