摘要： In a method for exchanging routing messages in a wireless meshed communication network with network nodes and a root node, a routing tree is set up with data transmission paths. The root node sends routing requests at regular time intervals to set up the paths, wherein a request contains a specification for a first bidirectional path mode or a second unidirectional path mode. At a respective node, a first field is used to indicate a first or a second node state. If, upon receipt of a request, the first field is in the first state, a routing response is always sent and otherwise not. Next, the node checks the mode specified in the request, ensuring that the respective mode is set. In case of a node to root data transmission, a node also ensures that the first field of the respective network node is in the first state.

摘要： Systems and methods for routing packets by nodes in an ad hoc network in accordance with a link quality source routing protocol are disclosed. Route discovery, route maintenance, and metric maintenance are designed to propagate and keep current link quality measurements. Metric maintenance includes a reactive approach for links that a node is currently using to route packets, and a proactive mechanism for all links. Nodes are configured to include a send buffer, a maintenance buffer, a request table, link quality metric modules, and preferably a neighbor cache and a link cache. The invention allows for asymmetric links in the network. The invention may be implemented within a virtual protocol interlayer between the link and network layers. The invention may employ any particular link quality metrics, including metrics based on probing techniques as well as metrics based on knowledge gained in other ways.

摘要： Methods, systems, and devices for wireless communications are described. In some communications systems, interference may impede signaling between a base station and a target user equipment (UE) such that a base station may identify a donor UE to relay communications to the target UE. The donor UE may receive a coded data packet from the base station, and may identify a radio network temporary identifier (RNTI) scrambling code for the packets addressed to the target UE. In cases where the donor UE identifies that the packet has an RNTI scrambling code associated with the target UE, the donor UE may forward the coded data packet to the target UE base on the RNTI scrambling code. Such early detection of data packets addressed to the target UE may allow for the UE to forward a data packet without fully decoding the packet.

摘要： A node includes a deterministic path that conveys packets from input ports to output ports via a deterministic switch. The node also includes a statistical path that conveys packets from the input ports to the output ports via a statistical switch. A deterministic scheduler selectively enables the first path or the second path based on traffic properties that indicate whether the packets are in a stochastic flow or a deterministic flow. In some cases, the deterministic scheduler includes timing circuitry that determines an arrival time of a packet at an input port of a node and enabling circuitry that generates signaling that selectively enables a first path for conveying the packet via a deterministic switch or a second path for conveying the packet via a statistical switch. The selection is based on whether the arrival time indicates that the packet is in a stochastic flow or a deterministic flow.

摘要： A combined User Plane (UP) node optimizes the UP data stream handling for 4G/5G network operation as follows. The combined UP node, which includes an access data plane node, an intermediate data plane node, an anchor data plane node, and a session handling process module. If the IP addresses or the namespaces of the access data plane node, the intermediate data plane node, and the anchor data plane node are different, then the downlink and uplink packet stream handling utilizes an intermediate interface path within the combined UP node. If the IP addresses or the namespaces of the access data plane node, the intermediate data plane node, and the anchor data plane node are same, then the downlink and uplink packet stream handling does not utilize an intermediate interface path within the combined UP node, but TEID of the unutilized intermediate interface path is used in PFCP response message.

摘要： Disclosed are techniques for routing messages from a message delivery network (MDN) to one of a plurality of end user carriers, wherein there are a plurality of message routes capable of servicing each end user carrier. An MDN may receive a message from a sending message service provider. The MDN may identify a destination end user carrier servicing the end user device for the message. The MDN may produce a rank ordered list of message routes from the MDN to the destination end user carrier by solving a linear constrained optimization model configured to converge upon an optimized ranking of message routes from the MDN to the plurality of end user carriers. The MDN may then attach the rank ordered list of message routes to the message before forwarding the message to a gateway within the MDN. The gateway may then initially attempt delivery of the message using the highest ranked message route from the rank ordered list of message routes. If the delivery attempt fails, the next highest ranked message route may be attempted until the message is delivered or no other message routes are available to try. Other embodiments are described herein.

摘要： At a source node, a plurality of packets may be determined for transmission to a destination node in a network comprising a plurality of network nodes. A transmission rate of the plurality of packets from the source node to a neighbor node in the network may be adaptively controlled, based on a determination of a current status of the network by utilizing a plurality of parameters that are estimated via a reinforcement learning routing algorithm. The plurality of parameters include an estimated cost value representing a current cost to transmit the plurality of packets to the destination node via the network. Transmissions from intermediate nodes may also be adaptively deferred based on a determination of a current status of the network by utilizing the plurality of parameters.

摘要： Systems and methods of mesh network communication enabling a relay node to autonomously select a packet propagation mechanism. Upon receiving a packet, which may carry an indication for flooding propagation as set by the edge node originating the packet, or carry no specification for any propagation mode, the relay node determines whether the packet is eligible for routing-propagation based on a number of factors, such as whether there is an existent valid route from the source node to the destination node, whether the packet is originated from a friend edge node, and whether a route discovery process has been initiated. Accordingly, the relay node may change the indication to routing propagation and forward it by routing-relaying. Thus, the packet can be propagated over the mesh network by routing propagation, despite the initial setting for flooding propagation as specified by the edge node or no setting by the edge node.

摘要： In a self-organizing wireless multihop network, each node device selects operation among short-range (SR) and long-range (LR) communication modes, among which the SR mode uses a higher data rate than the LR mode. Each node device advertises connectivity link availability for neighboring node devices, and selectively initiates a link in response to connectivity availability advertised by at least one neighboring node device. The availability advertising is performed in the SR and the LR communication modes, according to a periodicity that is dynamically-variable in response to prevailing circumstances in the local neighborhood. The link initiation is selectively performed in one of either the SR or the LR communication mode based on selection criteria that include data throughput performance associated with different neighboring node devices with which connectivity is available via a certain communication mode.
