| 摘 要： | 在电力通信网络中，负载均衡能够减少瓶颈节点的过载情况，有助于提升电力通信系统的可靠性和网络资源利用率。针对电力通信网络独特的结构与流量特征，提出一种确定性路由与机会路由相结合的负载均衡的路由协议。每个节点从以自己为中心的区域中选出候选节点集合负责转发数据包，候选节点依据局部的准确代价与远处的估计代价划分优先级并决定转发概率。与负载均衡优先的开放最短路径优先（LBA-OSPF）协议相比，节点平均负载降低了32.3%，端到端时延减少了50.3%。

| Abstract: | In electric power communication networks, load balance can reduce overloading on bottlenecks and improve the reliability and utilization of network resources. According to structure and flow characteristics of electric power communication network, a load balanced routing protocol combined with deterministic routing and opportunistic routing was proposed. Each node determined candidate sets to relay data packets from an area centered by it. Each candidate according to the precise local cost and the estimated remaining cost, and the forwarding probability was determined based on the priority. Compared with Load Balance Advanced-Open Shortest Path First (LBA-OSPF) protocol, the proposed routing protocol can reduce the average load by 32.3% and reduce the end-to-end delay by 50.3%. |
