Abstract: Disclosed embodiments relate to a Hierarchical Do-Dag based RPL (H-DOC) network configuration where the network address of each node corresponds to its location within the hierarchical network. Network addresses are initialized hierarchically. Candidate patent nodes signal availability. Candidate child nodes respond to a selected candidate parent node with a temporary address. The selected candidate parent node acknowledges selection and communicates a hierarchical address for the child node in a transmission to the temporary address. The child node changes its address to the hierarchical address from the parent node. When a node switches parent nodes, it signals the old parent node to deallocate it as a child node, and then signals a selected candidate parent node with a temporary address.

Abstract: A method for communicating in a wireless sensor network (WSN) is described. Using control logic, a first wireless transceiver is caused to transmit a wireless packet to a node in a wireless sensor network. The control logic bases its causing on a transmission coinciding with a break in transmission for a second wireless network, such that the transmission from the first wireless transceiver does not coincide with transmissions made on the second wireless network. Time synchronized channel hopping (TSCH) slot frames for wireless packet transmission in the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing TSCH. Wake up sequence transmissions for the wireless sensor network are caused to be time offset if the first wireless transceiver is utilizing coordinated sampled listening (CSL).

Abstract: A network includes a plurality of parent nodes to communicate in a wireless network via a wireless network protocol. A network node establishes a network connection to one of the parent nodes of the plurality of parent nodes in response to received beacons from the parent nodes. A signal analyzer in the network node processes a received signal strength of the beacons and the number of beacons received over a given time period from each of the parent nodes. The signal analyzer selects the parent node by analyzing the received signal strength for a number of beacons received from each parent node with respect to a number of expected beacons transmitted from each parent node of the plurality of parent nodes over the given time period.
