  • Patent number: 7996031
    Abstract: A method and system for providing a network protocol for utility services are disclosed are disclosed. In one embodiment, a computer-implemented method comprises discovering a utility network, wherein a constant powered meter sends network discovery messages to find the utility network. Neighboring meters are discovered, wherein the constant powered meter sends hello messages periodically. The constant powered meter is registered with the utility network. Further, the battery powered meter finds and associates itself with a constant powered meter. The constant powered meter also registers its associate battery powered meter with the utility network. The constant powered meter sends a node registration message to the gateway of the utility network. The constant powered meter can sense outage problems with the gateway and the neighbors of its network, and search and migrate to an alternate network.

  • Patent number: 6445688
    Abstract: A method and a system are provided to determine and thus select the best choice for antenna to be used by a network device having a plurality of directional antennas for a particular sending source. The determination is made using on a metric based on the success rate of packets received at a particular directional antenna from the sending source and secondarily on a received signal strength indicator. The determination is stored and made available for processing such that a router is able to request communication through a device with a destination via the second wireless communication device without knowledge of the best antenna match. In a specific method the first communication device broadcasts packets, via each associated directional antenna, to query for the existence of the second wireless communication devices.
