Abstract
A smart grid, as its name implies, is an intelligent grid, which features two-way transmission for electricity and information. A smart grid can deliver various types of electrical services and streamlined, highly efficient energy consumption, but only if its communication systems are highly reliable. A smart grid can be based on wireless networks, which offer high speed and low cost, but problems with wireless technology can impair communications performance and destabilize the smart grid. Wireless local area network (LAN) mesh networks based on IEEE 802.11s can serve as the backbones of smart grids. IEEE 802.11s provides flexible, scalable, high-speed communications with low installation and management costs. In this paper, we first describe IEEE 802.11s, default routing protocol, Hybrid Wireless Mesh Protocol (HWMP); Even though HWMP has several shortcomings that destabilize smart grids, we propose a novel scheme to improve smart grid routing reliability. We present a simulation of our proposed scheme using ns-3 simulation software, and prove that our method can improve smart grid reliability.

We evaluate the performance of our proposed scheme through ns-3 simulation [13] the results prove that it is useful for improving smart grid reliability and feasible to deploy
The proposed scheme compares the packet delivery ratio, total count of data packets that are successfully received, transmission delay and throughput; these comparisons are made relative to the route selection algorithm of the IEEE 802.11s Hybrid Wireless Mesh Protocol (HWMP) and the route selection scheme proposed by [15], [16]
Summary
A smart grid includes several technologies related to electric power, communication, and control. A smart grid can support transmission of power information and manage electrical services promptly [2]. A key characteristic of smart grid is bidirectional flows of electricity and information [3]. It consists of smart meters, sensors, a data transmission network, and a meter data management system (MDMS). The purpose of AMI is to collect data from sensors and share information between the electric power grid equipment and smart meters [5]. Smart grids can manage electric devices using two-way information flows between AMI and smart meters.
