In order to improve the management mechanisms of the electric energy transport infrastructures, the smart grid networks have associated data networks that are responsible for transporting the necessary information between the different elements of the electricity network and the control center. Besides, they make possible a more efficient use of this type of energy. Part of these data networks is comprised of the Neighborhood Area Networks (NANs), which are responsible for interconnecting the different smart meters and other possible devices present at the consumers' premises with the control center. Among the proposed network technologies for NANs, wireless technologies are becoming more relevant due to their flexibility and increasing available bandwidth. In this paper, some general modifications are proposed for the routing protocol of the wireless multi-hop mesh networks standardized by the IEEE. In particular, the possibility of using multiple paths and transmission channels at the same time, depending on the quality of service needs of the different network traffic, is added. The proposed modifications have been implemented in the ns-3 simulator and evaluated in situations of high traffic load. Simulation results show improvements in the network performance in terms of packet delivery ratio, throughput and network transit time.
为了改善电能输送基础设施的管理机制，智能电网网络关联了数据网络，负责在电网的不同元素和控制中心之间传输必要的信息。此外，它们还使得这种类型的能源能够得到更有效的利用。这些数据网络的一部分由邻里区域网络（NANs）组成，负责将不同的智能电表和其他可能存在于消费者场所的设备与控制中心互连。在为 NANs 提出的网络技术中，由于其灵活性和可用带宽的增加，无线技术变得越来越重要。在本文中，针对 IEEE 标准化的无线多跳网状网络路由协议提出了一些一般性修改。具体来说，根据不同网络流量的服务质量需求，同时添加了使用多条路径和传输信道的可能性。所提出的修改已在 ns-3 模拟器中实现，并在高流量负载情况下进行了评估。仿真结果表明，在数据包投递率、吞吐量和网络传输时间方面，网络性能得到了提高。
