Abstract
Information gathered from the Smart Grid (SG) devices located in end user premises provides a valuable resource that can be used to modify the behavior of SG applications. Decentralized and distributed deployment of neighborhood area network (NAN) devices makes it a challenge to manage SG efficiently. The NAN communication network architecture should be designed to aggregate and disseminate information among different SG domains. In this paper, we present a communication framework for NAN based on wireless sensor networks using the software defined networking paradigm. The data plane devices, such as smart meters, intelligent electronic devices, sensors, and switches are controlled via an optimized controller hierarchy deployed using a separate control plane. An analytical model is developed to determine the number of switches and controllers required for the NAN and the results of several test scenarios are presented. A Castalia based simulation model was used to analyze the performance of modified NAN performance.

A novel approach for handling the SG applications within a NAN domain is proposed based on the SDN paradigm
Summary
The conventional power grids are on the verge of being upgraded to become Smart Grids (SG). Smart meters and sensors nodes installed in the neighborhood area networks (NANs) would be connected to SDN enabled switches that provide the data layer traffic forwarding. SDN becomes an appropriate candidate for SG communication networks, where a huge number of M2M devices are controlled, monitored, and smart data aggregation is mandatory to run the delay sensitive applications. The research presented was motivated by the observation that there is a need for SDN based SG NANs to facilitate devices connected by wireless or wired communication technologies. A novel SDN based NAN communication framework for WSN connected devices Consideration of delay sensitive and delay tolerant SG applications Analysis of the network performance A novel algorithm that improves traffic flows over the WSN An analysis of the number of controller and switches required in the NAN to support the WSN connected devices.
