摘要： One embodiment of the present invention implements a FHSS system using single transmitter/multiple receiver transceivers. Such transceivers are configured to receive multiple FHSS channels (e.g., five channels) but only transmit on one channel. In an embodiment, one channel is dedicated to high priority traffic and the other four channels are dedicated to standard traffic. In receiving a high priority message, the transceiver is configured to address the high priority traffic first. For example, because the single transmitter/multiple receiver transceivers only has one transmitter, such transceiver may immediately dedicate it transmitting resources to addressing the received high priority data. Other embodiments are disclosed that implement multiple priorities among a plurality of communication channels.

摘要： Methods and systems for providing a network and routing protocol for utility services are disclosed. A method includes discovering a utility network. Neighboring nodes are discovered and the node listens for advertised routes for networks from the neighbors. The node is then registered with one or more utility networks, receiving a unique address for each network registration. 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 node can sense transient link problems, outage problems and traffic characteristics. Information is used to find the best route out of and within each network. Each network node maintains multi-egress, multi-ingress network routing options both for itself and the node(s) associated with it. The node is capable of several route maintenance functions utilizing the basic routing protocol and algorithms.

摘要： One embodiment of the present disclosure sets forth a technique for convergence and automatic disabling of access points in a wireless mesh network. Specifically, an access point within a wireless mesh network computes one or more network metrics to determine whether the metrics are unfavorable or favorable. If the network metrics are favorable, then the access point disables the access point's network connection. An access point turns the network connection back on based on whether a routing was lost for at least a preset amount of time, utilization of one or more neighboring access points is above a preset value, or one or more network metrics have degraded by a certain percentage value. One advantage of this approach is that cost savings may be achieved when the number of access points dynamically changes to accommodate varying communications conditions.

摘要： A method of routing in a network includes dividing a time corresponding to a predetermined maximum registration age of a first node registered with a second node into a number of first time intervals and second time intervals. The first time intervals each have a predetermined duration and the second time intervals each have a duration greater than the predetermined duration of the first time intervals. Each of the first and second time intervals are assigned a metric designating a cost associated with a path between the first node and the second node. The metric increases in value for each of the first and second time intervals as registration age increases. The second node sends a message including the metric associated with the time interval during which it is transmitted.

摘要： In an embodiment of a wireless network, when a node joins the network and receives a routing advertisement, such a node transmits the routing advertisement to all its neighbors. The node then receives transmission from the neighboring nodes indicating interest in joining the advertised network. If more than a threshold number of neighboring nodes are interested in the advertised route, the newly joining node inserts the route advertisement in a beacon transmission. If there is not a threshold level of interest, the node unicasts only to the neighbors who indicated interest in the advertised network. In an embodiment, the node repeats the above steps on a predetermined time basis (e.g., one per day) in order to determine interest in the advertised route that may have newly arisen.

摘要： One embodiment of the present invention sets forth a technique for a node within a network to adjust one or more routing parameters based on certain network parameters. A node monitors certain network metrics such as the mean time between routing drops. In response to changes in these network parameters, the node changes certain routing parameters, such as the holddown time. The node may store network metrics and associated routing parameters that result in preferred network operating conditions. The node may pre-load these beneficial settings upon the occurrence of a particular condition such as a system reset of the node. Moreover, a node may share these beneficial settings with neighboring nodes on the same network. One advantage of this approach is that cost savings are achieved when a node within a network may be installed without preconfiguring the node with specific routing parameters.

摘要： A node within a wireless mesh network performs a path analysis on an advertised path to an access point that has a cost value less than the cost value of the current primary path to the access point. Depending on the cost value difference between the respective cost values of the advertised path and the current primary path, the node may perform a different type of path analysis. Based on the result of that path analysis, the node may change paths to the access point and use the advertised path as the primary path. Further, the node maintains a secondary path so that, in the event that the primary path fails, the node can default to using the secondary path.
