20140293276 | DISTRIBUTING LIGHT INTENSITY READINGS IN A WIRELESS MESH - A method for controlling a light source associated with an environment includes: receiving, over a wireless mesh network and by a control node corresponding to the light source, a first light intensity value for the environment from a first sensor node; calculating, by the control node, a resulting light intensity (RLI) value based on the first intensity value; determining, by the control node, that the RLI value exceeds a light intensity threshold; and modifying, by the control node and in response to determining the RLI value exceeds the light intensity threshold, an output of the first light source. | 10-02-2014 |
20150105932 | THROTTLING TO CONTROL THERMAL PROPERTIES THROUGH A NODE - The invention relates to a method for controlling thermal properties of a node. The method steps include calculating, using a temperature reading, a transmission duty cycle of the node, calculating a data amount capable of being transmitted with the transmission duty cycle, and transmitting, from a network interface of the node, a plurality of available data at a rate less than the data amount based on a priority of the plurality of available data. | 04-16-2015 |

20090245270 | Method and System of Updating Routing Information in a Communications Network - A method of updating routing information in a network where reboot information of other nodes in the network is used to determine whether a given node has recent route updates. If the reboot information indicates the given node has not recently rebooted, then routing information from that given node is used to update the routing information of the comparing node. The reboot information may be a reboot counter which is incremented by a node in response to the node going through a reboot process. When a node reboots, it may request the reboot counter from neighboring nodes. The received reboot counter is compared to the stored reboot counter for at least one node. The rebooting node may choose to receive routing information from a node which has not had its reboot counter changed from the stored reboot counter. In the event none of the neighboring nodes have an unchanged reboot counter, requests may be made for the reboot counters of other nodes, which may be compared to the corresponding stored reboot counters, until the rebooting node discovers a node which has not recently rebooted according to the reboot counter, and may then download routing information from that node. | 10-01-2009 |
20100103940 | Rapid Dissemination of Bulk Information to Widely Dispersed Network Nodes - Bulk information is transferred to nodes in a communication network having a plurality of widely dispersed nodes. The information can be an image, content, or configuration information. The information is uni-cast to a selection of nodes by a central node or server, to seed the information at certain nodes in the network. The information is then distributed by these seed nodes to every other node in the network. A first algorithm selects which nodes should be seeded with information by the central node. A second algorithm distributes information in the network on a query basis. | 04-29-2010 |
20100302062 | Method and System for Providing a Network Protocol for Utility Services - 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 | 12-02-2010 |
