Performance of reliable intelligent power line communication network for digital HPS ballast remote monitor and control

Power line communication (PLC) plays an important role in such no-new-wiring applications as digital HPS ballast remote management in new public lighting system. PLC data link especially with a large scale of ballast nodes is liable to be destroyed because of the dynamic channel properties. The reasons that lead to the failure of data link, the corresponding methods to enhance the reliability of PLC network are investigated, and the hybrid dynamic topology of the PLC network is studied, which is based on self-organizing algorithm in MAC layer with improved fault-tolerance ability. According to the study results, a low cost TDMA-like MAC protocol suitable for the hybrid PLC network initialized by self-organization algorithm is proposed and the performance is analyzed by M/D/1 model compared with polling. The general round robin cycle duration of PLC networks with hybrid structure that interested to remote monitor and control system is also presented.
