Abstract: A wireless communication system includes a first wireless network having first nodes each assigned a unique first address, a second wireless network having second nodes each assigned a unique second address, a border router node constituting an interface between the second network and a third wireless network, and at least one access point constituting an interface between the first and third networks. At least one of the first nodes is a mesh router node in the first network and a border router node in the second network (MR/BR node). The MR/BR node has unique addresses respectively assigned in the first and second networks. The MR/BR node receives a communication in the first network and transmits it to at least one second node in the second network. The MR/BR node receives a communication in the second network and transmits it to at least one first node in the first network.

Abstract: A method for locking out a remote terminal unit includes: receiving a lockout request, wherein the lockout request includes at least a public key associated with a user, a user identifier, and a terminal identifier; identifying a user profile associated with the user based on the user identifier included in the received lockout request; verifying the public key included in the received lockout request and permission for the user to lockout a remote terminal unit associated with the terminal identifier included in the received lockout request based on data included in the identified user profile; generating a lockout permit, wherein the lockout permit includes at least the public key included in the received lockout request; and transmitting at least a lockout request and the generated lockout permit, wherein the lockout request includes an instruction to place a lockout on the remote terminal unit.

Abstract: A plurality of nodes in a first network mitigate data restrictions on access points which are an interface between the first network and a second network. The access points advertise their access parameters to the second network to the nodes. The nodes maintain a list of the advertised access parameters of each access point. The nodes determine whether to transmit data to the second network according to a first transmission mode or a second transmission mode based on the data to be transmitted and the list of access parameters maintained by that node. In the first transmission mode, the node determines to transmit the data to a first access point having a lowest cost with that node. In the second transmission mode, the node determines to transmit the data to a second access point having fewer access restrictions to the second network than the first access point.

Abstract: A method for managing radio transmission in an endpoint device in a network includes: receiving, at a first endpoint device, a message requesting wake up of the first endpoint device; establishing a connection between the first endpoint device to a second endpoint device connected to the network; determining, at the first endpoint device, whether a secure command is received from the second endpoint device via the established connection within a predetermined period of time; and based on the received secure command, establishing a connection between the first endpoint device and the network via radio transmission, wherein the first endpoint device is configured to turn off radio transmission if the secure command is not received within the predetermined period of time.

Abstract: One embodiment of the present invention sets forth a dual mode smart grid meter configured to operate within both an automatic meter reading (AMR) system and an advanced metering infrastructure (AMI) system. An AMR transmitter periodically transmits metrology data for interoperation with AMR reading operations. An AMI transceiver responds to AMI queries and commands for interoperation with AMI requirements. The disclosed dual mode smart grid meter beneficially enables utility operators to deploy or upgrade metering devices within an existing AMR network without disruption meter reading operations, while simultaneously preparing for an overall upgrade to reading operations based on AMI protocols.

Abstract: One embodiment of the present invention sets forth a technique for transmitting data in a frequency hopping spread spectrum (FHSS) wireless communication system. A multi-channel receiver is configured to receive data from one or more channels simultaneously. The multi-channel receiver enables efficient implementation of a transmission protocol in which multiple candidate nodes within a wireless mesh network are polled for availability to receive a packet of data. The packet of data is transmitted to one or more available nodes based on prevailing link conditions, thereby increasing the likelihood of successful delivery. Data flooding may be selectively implemented to further increase the likelihood of successful delivery.

Abstract: A method for optimizing communication modes between network nodes includes: storing, in a first node in a communication network, a data success rate for each of a plurality of communication modes; receiving, by the first node, mode data from a second node in the communication network including at least a mode identifier for at least two of the plurality of communication modes; determining, by the first node, a metric for each of the at least two communication modes based on at least a data success rate of transmissions using the respective communication mode; selecting, by the first node, a preferred communication mode of the at least two communication modes based on the determined metric for each of the at least two communication modes; and transmitting, by the first node, an initiation data message to the second node via the communication network indicating the selected preferred communication mode.
