摘要:

为应对不同服务质量需求并提升智能电网通信的系统能力及可靠性,提出一种无线智能电表双路径维护基于因果树的认知技术. 因果树通过定义智能电表程序中的度量和事件之间的因果关系,以实现有效推理. 路径维护度量根据接收信号强度指标和数据包接收成功率明确了链路状态、链路质量、相应的动态转换等路由问题. 基于信道和电磁干扰所做的物理实验用于评估该种无线智能电表的可靠性.

Abstract:

In order to enhance system capability and reliability in diverse scenarios of smart grid traffic with different quality of service requirements, a cognitive technology of double path maintenance for wireless smart meters is proposed using causality tree. The causality tree performs efficient reasoning by using the underlying causal relationships between metrics and events which are defined in the program of smart meters. Path maintenance metrics identify routing design issues about link states, link qualities, and correlated dynamics transitions in terms of received signal strength indicator and packet reception rate. Physical experiments are used to evaluate the reliable performance of the wireless smart meters in the scenarios of channel and electromagnetic interference.

Key words: smart grid, wireless sensor networks, semantic metrics, machine to machine, quality of service
