Abstract:
Power line communication (PLC) is a promising technique for information transmission using existing power lines. We analytically model a finite-source PLC network subject to noise/disturbance and evaluate its call-level performance through a queuing theoretic framework. The proposed PLC network model consists of a base station (BS), which is located at a transformer station and connected to the backbone communication networks, and a number of subscriber stations that are interconnected with each other and with the BS via the power line transmission medium. An orthogonal frequency division multiplexing (OFDM) based transmission technique is assumed to be used for providing the transmission channels in a frequency spectrum. The channels are subject to failure during service due to noise/disturbance. When a channel is in failure, its associated call will wait at the channel until the channel is recovered. We model this process and determine the steady-state solution and derive several p
erformance metrics of interest. Numerical and simulation results are presented for the purpose of performance evaluation. The proposed modeling method can be used for evaluation and design of future PLC networks.
