Abstract: A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

Abstract: A network includes at least one node to communicate with at least one other node via a wireless network protocol. The node includes a network configuration module to periodically switch a current node function of the node between an intermediate node function and a leaf node function. The switch of the current node function enables automatic reconfiguration of the wireless network based on detected communications between the at least one node and at least one intermediate node or at least one leaf node via the wireless network protocol.

Abstract: In an example method of target position estimation, the method includes calculating initial estimated positions of a target transmitter. Each of the initial estimated positions is based on an angle of arrival estimate received from a locator. The method includes generating an error projection associated with each of the initial estimated positions. The error projection is based on azimuth and elevation error characteristics of the locator associated with the initial estimated position. The method includes creating a select group of the locators based on overlaps of the error projections, wherein the select group of locators comprises a subset of the locators. The method includes calculating a refined estimate of the position of the target transmitter based on the initial estimated positions associated with the select group of locators.

Abstract: A method for managing Internet Protocol Version 6 (IPv6) addresses in a wireless sensor network is provided that includes storing, on a wireless sensor device in the wireless sensor network, a prefix of an IPv6 address in association with a key, forming an address indicator for the IPv6 address, the address indicator consisting of the key and a node address of the IPv6 address, and storing the address indicator in at least one memory location on the wireless sensor device in lieu of the IPv6 address.

Abstract: A network includes at least two nodes that employ a routing protocol to communicate across a network. One of the nodes is a parent node and another of the nodes is a child node of the parent node. An address generator assigns a unique network address to the child node by appending an address value of a number of bits to a parent address of the parent node to create the unique network address for the child node.

Abstract: A network includes an intermediate node to communicate with a child node via a wireless network protocol. An intermediate node synchronizer in the intermediate node facilitates time synchronization with its parent node and with the child node. A child node synchronizer in the child node to facilitates time synchronization with the intermediate node. The intermediate node synchronizer exchanges synchronization data with the child node synchronizer to enable the child node to be time synchronized to the intermediate node before the intermediate node is synchronized to its parent node if the intermediate node has not synchronized to its parent node within a predetermined guard time period established for the child node.

Abstract: A method for operating a node in a wireless network is provided that includes computing an estimated time drift between the node and a parent node of the node, and using the estimated time drift and a number of hops between the node and a root node of the wireless network to determine a keep alive period for the node.
