Abstract: It is provided a method for enabling an SCTP packet to be encapsulated in a UDP packet the method being performed by a source network node. The method comprises the steps of: obtaining a source number based on an identifier of the source network node; obtaining a destination number based on an identifier of a destination network node; generating an SCTP packet, which comprises setting a source port of the SCTP packet to a predefined port number and setting a destination port of the SCTP packet to the destination number; generating a UDP packet, which comprises setting a source port of the UDP packet to the source number and setting a destination port of the UDP packet to the destination number; encapsulating the SCTP packet in the UDP packet; and sending the UDP packet for transport to the destination network node.

Abstract: A communication system includes a central cloud server that decreases a gain of a currently active path, which corresponds to a primary communication path between a radio access network (RAN) node and one or more user equipment (UEs) via a first set of edge devices, until the currently active path becomes dormant. A gain of a dormant path, corresponding to a secondary communication path is increased until the dormant path becomes a new active path. Further, at least one edge device of the second set of edge devices is caused to transmit one or more beams of radio frequency (RF) signals in one or more specific directions towards one or more new neighboring nodes to establish the secondary communication path that is used as a backup communication path between the RAN node and the one or more UEs via a second set of edge devices different from the first set of edge devices.

Abstract: 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.

Abstract: Systems and methods include a WSN having sensor nodes that are configured with electronic circuitry for interfacing with one or more associated sensors. The WSN also includes a gateway sensor node configured to receive sensor data from and forward instructions to the one or more sensor nodes, and a server configured to control the WSN in combination with the gateway sensor node. The WSN also includes circuitry configured to recognize a link break within a data communication route of the WSN via a routing protocol, and buffer incoming packets from a source node. The circuitry is also configured to propagate a RERR message of the link break to the plurality of sensor nodes, and build a bypass route around the link break of the data communication route towards a destination node. The circuitry is also configured to send the buffered incoming packets to the destination node through the bypass route.

Abstract: In one embodiment, a particular node in a shared media computer network may determine a set of network parameters for the network, and a timing of super-frames in the network, each super-frame having one or more frames, each frame divided into a plurality of timeslots. In addition, the particular node computes a discovery scheduling function using its own identification to determine in which particular timeslot of the frames to transmit a network discovery packet. Accordingly, the particular node may transmit the network discovery packet in the particular timeslot of the frames. In an additional or alternative embodiment, the particular node may receive a network discovery request from a requesting node. In response, the particular node determines whether it is free to reply to the network discovery request based on parameters in the network discovery request, and if free to reply, may transmit a network discovery packet to the requesting node.

Abstract: A method in a relay device for forwarding messages in a mesh based network comprises receiving a message to be forwarded (step 201), and determining whether the message is to be forwarded using a routing profile associated with the message (step 203). If so, the message is routed according to a routing profile (step 205). If not, the message is outed using a flood procedure (step 207).
