Modeling and Analysis MAC Layer Performance for IEEE 802.11s Wireless Mesh Network in Smart Grid

IEEE 802.11s based wireless mesh networks (WMN) recently have been proposed as an important networking technology to deploy in Smart Grid (SG) for data collection and remote control purposes. In this paper, we focus on modeling and analyzing the MAC layer performance of EDCA for IEEE 802.11s wireless mesh networks in the smart grid, taking into account the impact of hidden nodes and different QoS requirements of smart grid applications. We first develop a new Markov chain model to analyze the back-off process for different applications with hidden nodes problem. Then based on the analytical model, we derive a few MAC layer performance metrics. Finally, the proposed analytical model is validated via comparing the analytical results with simulation results by ns3 in NAN scenarios with various applications.
