A network includes a mobile network node (MNN) that includes a mobile node communications manager (MNCM) to facilitate wireless communications to a plurality of stationary network nodes (SNNs) in a wireless network via a wireless network protocol. The MNCM utilizes a multicast address received over the wireless network. The multicast address is assigned to a predetermined network time slot to communicate uplink data from the MNN to the SNNs. The MNN receives downlink data via a separate predetermined network address and time slot assigned to a given SNN.

09794860 · 2017-10-17 · ·

Geocast-based situation awareness utilizing a scalable, distributed ad hoc geocast protocol as a communication primitive, may provide a field common operating picture (FCOP) for providing location tracking, movement history, telemetry, and messaging in near real time to all operators in a scenario. Information may be transferred using a query/response geocast message protocol. Caching on devices may be utilized to gain scalability. A query message may have a payload containing a type indication and a header containing a description of a geocast region of intended reception, which may comprise the monitored region, the location of the monitorer, or any appropriate combination thereof. Response messages may be sent from devices located in the monitored region to an area containing the location of the sender of a query. A response message may contain monitored information, such as current location, telemetry data, and/or recent movement history, or the like.

Satellite communications networking

A method of operating a satellite communication network is disclosed. The network includes a plurality of satellites interconnected by a plurality of satellite-to-satellite communication links. Each of the plurality of satellites is configured to communicate with at least one ground station using respective ground-satellite communication links. The method includes transmitting a routing table to each of the satellites. Each routing table has a list of destination satellites, and defines at least two possible routes leading to it. An alert message identifying a problem communication link is transmitted to a subset of the plurality of satellites. In response to receiving the alert message, subsequent data packets are routed through the communication network by the satellites using their respective routing table to avoid the problem communication link.

Distributed wireless gateway

A distributed wireless gateway comprises several switches. Each switch is coupled to a respective set of wireless access points. When a given switch receives a packet from one of its wireless access points, it creates a mapping between that access point and the host that sent the packet to the access point. The given switch advertises to other switches in the distributed wireless gateway reachability information that maps that host to the switch, enabling the other switches to identify the given switch as the next hop when they receive a packet destined for that host.

A packet sending method includes: receiving, by a first node, a first broadcast data packet sent by a second node; and if a sequence number of the first broadcast data packet equals 1 plus a sequence number of a latest data packet saved by the first node, and the first node does not receive, within a first preset time period, a first acknowledgement indication for the first broadcast data packet of the second node, sending, by the first node, a first broadcast acknowledgement packet when the first preset time period elapses, where the first broadcast acknowledgement packet includes the first acknowledgement indication, and the first acknowledgement indication includes the sequence number of the first broadcast data packet and an address of the second node. This method could resolve acknowledgement packet implosion while ensuring broadcast packet reliability of a wireless mesh network.

Route optimization for on-demand routing protocols for mesh networks

Various embodiments implement a set of low overhead mechanisms to enable on-demand routing protocols. The on-demand protocols use route accumulation during discovery floods to discover when better paths have become available even if the paths that the protocols are currently using are not broken. In other words, the mechanisms (or “Route Optimizations”) enable improvements to routes even while functioning routes are available. The Route Optimization mechanisms enable nodes in the network that passively learn routing information to notify nodes that need to know of changes in the routing information when the changes are important. Learning routing information on up-to-date paths and determining nodes that would benefit from the information is performed, in some embodiments, without any explicit control packet exchange. One of the Route Optimization mechanisms includes communicating information describing an improved route from a node where the improved route diverges from a less nearly optimal route.
