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 system is provided. In some examples, the system includes a control circuit and a plurality of monitor circuits including a first monitor circuit. In a production mode, the control circuit is configured to test the plurality of monitor circuits. In a storage mode after testing the plurality of monitor circuits in the production mode, the control circuit is configured to test the plurality of monitor circuits more than once. In an assembly mode after testing the plurality of monitor circuits in the storage mode, the control circuit is configured to test the plurality of monitor circuits. In one or more examples, the control circuit is configured to skip the storage mode and test the plurality of monitor circuits in the assembly mode after testing in the production mode.

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.

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 a first wireless node that communicates over a wireless network connection. The first wireless node includes a first encryption engine that processes a first initialization data set and a current transmit sequence associated with a current communication to generate a next transmit sequence that is employed to communicate with a second wireless node that derives a next received sequence that corresponds to the next transmit sequence to process a subsequent communication.
