In one embodiment, a parent node in a network observes time slot usage of a channel hopping schedule by one or more child nodes of the parent node to communicate with the parent node. The parent node also identifies high priority traffic from a particular child node. The parent node detects time contention for the high priority traffic based on an indication that at least a portion of the traffic has been rerouted by a particular child node to a different parent node. In response to detecting the time contention, the parent node adjusts a communication strategy used by the one or more child nodes.

A method, system and apparatus are disclosed. In one or more embodiments, a network node configured to communicate with a wireless device (WD) is provided. The network node configured to, and/or including a radio interface and/or including processing circuitry configured to: receive information indicating a timing offset (T′.sub.Δ), determine transmission timing for downlink transmission based on the timing offset (T′.sub.Δ) and at least one estimated timing value, and perform downlink transmission based on the determine transmission timing.

A data transmission method, an apparatus, and a computer storage medium are provided. A first routing node receives downlink data of a terminal device. The first routing node sends a downlink paging request to a core network device, where the downlink paging request is used to indicate the core network device to search for a second access network device corresponding to a current location of the terminal device. The first routing node receives second routing information from a routing management node, where the second routing information is determined by the routing management node based on a routing information update request from the second access network device. The first routing node sends the downlink data to the terminal device via the second access network device based on the second routing information.

A method and apparatus for routing packets in a network, such as a satellite mesh network. Geographic routing is employed in which packets specify their physical destination location. Network nodes maintain physical location information for nodes, along with routing information, for a limited portion of the network which is local thereto. At each node and for each packet, a target node is selected from the limited portion. The target node may be the node which is closest in orthodromic distance to the physical destination location. Based on the routing information, a next node belonging to the limited portion of the network and located along an available network path between the node and the target node is determined, and the packet is forwarded to the next node.

A network controller is configured to cause a network to implement a primary network configuration of a network and a secondary network configuration as a backup to the primary network configuration. The network controller may be configured to receive information from a plurality of nodes of a network and information related to the client data to be transmitted through the network. Based on the node information, the network controller is configured to determine available nodes and possible links in the network and then determine a topology of the network. The primary network configuration is determined based on the topology. The network controller then sends instructions to the plurality of nodes of the network to implement the primary network configuration and to switch to a secondary network configuration where a failure of the primary network configuration occurs, wherein the secondary network configuration implements mobile ad-hoc networking in the determined topology.

Provided is a process that includes obtaining a directed acyclic graph describing a plurality wireless connections between a plurality of downstream nodes forming a multi-path route to an Internet connected wireless transceiver; determining an encoding kernel specifying transformations to be performed by the plurality of downstream nodes on data received from upstream nodes; transmitting at least part of the encoding kernel to at least some of the downstream nodes; and transmitting data from a data source to a downstream node in the directed acyclic graph specified by the encoding kernel such that the data is conveyed through the multi-hop, multi-path route to the Internet connected wireless transceiver.

An information processing device acquires a first future position where the moving object travels in the future; acquires a second future position where another moving object travels in the future; judges a current communication environment with another moving object based on a signal received from another moving object; corrects the current communication environment based on the acquired first future position and the acquired second future position, and judges a future communication environment with another moving object based on the corrected current communication environment.

An access point (AP) includes a transmitter (TX) circuit, a receiver (RX) circuit, and a control circuit. The control circuit negotiates with at least one another AP via the TX circuit and the RX circuit, for setting up a coordinated service period (SP). In addition, a method for setting up the coordinated SP in a multiple AP environment includes: sending a request frame from a first AP to at least one second AP, wherein the request frame includes a plurality of SP parameters; receiving a response frame generated from the at least one second AP in response to the request frame; and in response to the response frame, setting up the coordinated SP by sending a setup frame to the at least one another AP, wherein the setup frame is set by updating at least a portion of the plurality of SP parameters.
