Abstract
The Advanced Metering Infrastructure (AMI) is a fundamental component of the Smart Grid architecture. The AMI consists of a collection of Neighborhood Area Networks (NANs), which interconnects the smart meters to the utility company. In this paper, we address two important performance metrics regarding the NAN design, the topology's resilience and the network capacity. We propose an analysis methodology in order to determine the appropriate transmission power and the required number of gateways for wireless-enabled mesh-connected architectures. We employ a graph-theoretic approach for the analysis. Furthermore, we assume wireless NANs based on the new IEEE 802.15.4g standard. A planning tool has been implemented using software Mathematica in order to automate our approach. Simulation results show interesting tradeoffs between the performance metrics and the network design parameters, thus providing useful insights for the NAN designer.
