Abstract
The media access control protocols of low voltage power line carrier (PLC) communication are the important factors for the network performance including bandwidth availability ratio and access delay. Considering the relatively low performance due to the asymmetric PLC communication channels and noise interference, this paper proposes an improved adaptive p-persistent carrier sense multiple access (CSMA) game optimization method for the limited load mesh network in low voltage PLC communication. Each node estimates the current state of the game by using the hidden Markov game model. Then each node adaptively regulates the equilibrium strategy of receiving and transmitting terminals based on the game result. The data transmission is controlled to reduce the collision probability of data packets. The power line channel transmission status is guaranteed optimum state to increase the network saturation performance. The simulation results show that this method is effective.
