摘要： An electronic device may be operable to control access to a physical medium (e.g., airwaves, a copper cable, or an optical fiber) utilizing carrier sense multiple access (CSMA). The amount of time that the electronic device must sense the physical medium as being inactive before it permits transmission of a message onto the physical medium may be determined based on: the size of the message, the type of the message, the symbol rate at which the message is to be transmitted, and/or a channel onto which the message is to be transmitted. Similarly, other aspects of how and when electronic device transmits and/or receives on the physical medium may be controlled via one or more dynamically configurable parameters which may be configured based on characteristics of received and/or to-be-transmitted messages.

摘要： 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.

摘要： 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.

摘要： The invention proposes an improvement to increase the speed at which a Trickle algorithm can propagate update information in a multi-hop network, while still controlling the number of redundant transmissions and ensuring scalability of the algorithm. It does this by intelligently adapting the size of a listen-only period (t1, t2), depending on the fact if a node has recently received an update or not.

摘要： An electronic device may receive a protocol data unit (PDU) comprising a plurality of addressing bits. Data-link-layer processing of the PDU may be based on each of the addressing bits. Network layer processing of the PDU may be based on a first subset of the plurality of addressing bits. Transport-layer processing of the PDU may be based on a second subset of plurality of addressing bits. The data-link-layer processing may comprise determining whether the PDU is unicast-addressed or non-unicast-addressed. For a unicast-addressed PDU, the data-link-layer processing may comprise determining whether the PDU is destined for the electronic device based on a comparison of a Target ID field of the PDU and a device ID of the electronic device. For a non-unicast-addressed PDU, the Target ID field may not be present, and whether the PDU is destined for the electronic device may be determined based on other criteria.

摘要： In one embodiment, a network of nodes is configured to communicate according to a configuration of Available Routing Construct (ARC) chains as well as monitoring communication in the network, and/or selectively controls whether or not provisioned particular links will be used. One embodiment colors nodes of the network (e.g., a wireless deterministic network) along different paths through the network and marks packets with the color of each traversed node to track a path taken by a packet. One embodiment sends a particular packet through the network and marks over which links the packet traverses and aggregates these traversed links of other copies of the particular packet. One embodiment controls whether or not the provisioned time slots are used based on flooding a control packet through the network with enable or disable information for each of these links.

摘要： Media is distributed via a scalable ad hoc geographic routing/broadcast protocol. Media can be transmitted from a mobile device to a cluster of mobile devices that are geographically located in a particular region. Devices that are located between the source and the intended target can act as routers with the ability to forward data packets toward the intended destination. In essence, a geocast network cloud is established, allowing any device within the cloud to communicate with any other device in the cloud. Devices in the network can constantly change position and the transmission path through the network can be constantly changing. The geocast protocol adapts to the changing conditions.
