    • A method and system for providing a network and routing protocol for utility services are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a utility device (for example, a constant powered meter) sends network discovery messages to find the utility network. Neighboring meters are discovered and the device listens for advertised routes for one or more networks from the neighbors. The device is then registered with one or more utility networks, receiving a unique address for each network registration. Also illustrated in this invention disclosure is how each device of a class of devices (for example, battery powered meter) finds and associates itself with another device (for example, constant powered meter). The constant powered meter also registers its associate battery powered meter with the utility networks. The constant powered meter registers itself with the access points and the upstream nodes in the path out of each network. Each upstream node can independently make forwarding decisions on both upstream and downstream packets i.e. choose the next hop according to the best information available to it. The constant powered meter can sense transient link problems, outage problems, and traffic characteristics. It uses the information to find the best route out of and within each network. Each network device thus maintains multi-egress, multi-ingress network routing options both for itself and the device(s) associated with it.
    • 公开了一种用于为公用事业服务提供网络和路由协议的方法和系统。 在一个实施例中,计算机实现的方法包括发现公用事业网络,其中公用设备(例如,恒功率计量器)发送网络发现消息以找到公用事业网络。 相邻的仪表被发现,并且设备监听来自邻居的一个或多个网络的通告路由。 然后,该设备被注册到一个或多个公用事业网络,为每个网络注册接收唯一的地址。 本发明还示出了一类设备(例如,电池供电的仪表)中的每个设备如何发现并将其自身与另一设备(例如,恒功率仪表)相关联。 恒功率电表还将其关联电池供电的仪表与公用事业网络进行注册。 恒定功率的仪表自动注册每个网络中的接入点和路径中的上游节点。 每个上游节点可以独立地对上游和下游分组进行转发决策,即根据可用的最佳信息选择下一跳。 恒功率电表可以感测瞬态链路问题,中断问题和流量特性。 它使用这些信息来查找每个网络内外的最佳路由。 因此,每个网络设备为其自身和与其相关联的设备维护多出口,多入口网络路由选择。

    • A method and system for providing a network protocol for utility services are disclosed are disclosed. In one embodiment, a computer-implemented method determines whether a measured real signal strength differs from a an accepted real signal strength by a configurable control limit parameter. In the event the measured real signal strength exceeds either an upper or lower bound based upon the configurable control limit parameter a determination is made whether there has been an unacceptable number of measured real signal strengths that exceed either an upper or lower bound based upon the configurable control limit parameter. In the event there has been an unacceptable number of measured real signal strengths that exceed either an upper or lower bound, which may include reaching or exceeding a configurable out of bound incidence limit, then a determination is made to calculate a new accepted real signal strength.
