智慧電網是一個擁有智慧電表雙向傳輸電力和資訊特徵的智能電力網路。智慧電網造成的一個問題是需要高度可靠的通訊來維持不同種類的電器應用，並提供更好的能源效率。無線網路具有速度快、成本效益大的優點，但一些問題影響了智慧電網的性能，降低了智慧電網的可靠度。基於IEEE 802.11s的無線區域網路可以用作智慧電網基礎設施的骨幹網路。IEEE 802.11s不僅可以提供高速通訊，還可以提供高可擴展性和靈活性，低安裝和管理成本。在本文中，我們首先解釋了IEEE 802.11s預設路由協定，稱之為混合無線網狀協議(HWMP)，影響智慧電網鄰近區域網路可靠性的問題。然後，我們提出了一種改進智慧電網路由可靠性的新策略。最後，我們評估所提出的策略在ns-3模擬器上的性能。模擬結果表明我們的方法可以提高平均封包傳送率，平均封包傳送率是表示智慧電網網路可靠性的標準。

Smart grid, as its name implies, is a clever electric grid, which has a feature in two-way transmission about electricity and data information of smart meters. A topic caused by smart grid is to require high level of reliability about communication to support various kinds of electrical services and provide better efficient energy consumption. Wireless networks have advantages of high speed and great effect upon cost consumption, but some problems influence the smart grid communication networks performance and reduce the reliability of the smart grid. Wireless local area Network (LAN) mesh networks based on IEEE 802.11s can be used as smart grid infrastructure backbone network. IEEE 802.11s has ability to provide not only communication with high-speed but also high level of flexibility and scalability, which installation and management cost is low. In this paper,
we first explain IEEE 802.11s default routing protocol, Hybrid Wireless Mesh Protocol (HWMP) problems that affects the reliability of smart grid neighborhood area network. Then, A novel scheme is proposed to improve smart grid routing reliability. Eventually, we evaluate the performance of our proposed scheme using ns-3 simulator. Simulations show that our method can increase the average packet delivery ratio, which represents the reliability of the smart grid networks.
