Abstract: One example embodiment provides a method and system where a node in a utility network registers with one or more access point devices associated with one or more local area utility networks. The utility node generates a unique network address using a network address prefix of a network address associated with the access point device. The utility node registers with a DNS server. Messages sent to the utility node are routed through the access point corresponding to the received prefix used to generate the unique network address for the utility node. The network address for the utility node and access point may be IPv6 addresses and the network address prefix may be an IPv6 prefix, or may be an IPv4 address.

Abstract: A wireless communication system and method include a plurality of nodes that are part of a wireless local area network (LAN), and a plurality of access points connected to the wireless LAN and at least one wide area network (WAN). At least one of the nodes registers with at least two of the access points, and, for each of the access points with which that node registers, obtain a unique network address corresponding to that access point, such that the node obtains a plurality of unique network addresses each respectively associated with a corresponding one of the access points with which the node registers. The node can receive a message from an external network device via multiple routes through the WAN and the wireless LAN. Each of the multiple routes respectively corresponds to one of the unique network addresses obtained by the node.

Abstract: 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.
