Abstract: Embodiments for providing channel assignments for high density multi-channel multi-radio (MC-MR) wireless networks are generally described herein. In some embodiments, N nodes are provided in the network. T transceiver node groups are provided that include a first number of groups of nodes, wherein the first number of groups of nodes for a first of the T transceiver node groups have the N nodes assigned consecutively with a second number of nodes per each of the groups of nodes being a function of N. The first number of group of nodes for a remaining number of the transceiver node groups comprises N nodes with transceivers arranged to provide access to any node within a predetermined number of hops. The arrangement of the second number of nodes per each of the groups of nodes in the T transceiver node groups provides an optimized throughput per node.

Abstract: Techniques disclosed herein include systems and methods for accurately scheduling radar and radio events against each other. Specifically, a scheduling manager can schedule radar events based on scheduled radio events (wireless network communication events). A given radio schedule for a compact radar sensor can be a relatively complicated schedule, especially when the compact radar sensor operates as part of an ad hoc network. In certain embodiments, the scheduling manager identifies a radio transmission schedule of neighboring radar nodes or compact radar sensor units. Such a radio transmission schedule of neighboring nodes can include information on when neighboring nodes will be receiving or transmitting data. The scheduling manager then schedules radar events to be executed by the radar device at available times, or at times that do not overlap with scheduled radio events.

Abstract: The invention relates to a transport protocol and associated methods and stack architectures for improving the energy efficiency of transmitting packets through an ad hoc network. The protocol controls transmissions by taking into account per-packet energy limits, per-node loss tolerances, and/or minimum availability rates determined based on path quality measurements collected by packets traversing the network and application reliability requirements associated with various applications.

Abstract: Systems and methods for incorporating information corresponding to an end-to-end transmission in determining access to a communication medium include: receiving a first data packet, said first data packet comprising information corresponding to a destination node; determining an intermediate node for said first data packet; and transmitting, to said intermediate node, a request-to-send (RTS) corresponding to said data packet, said RTS comprising information corresponding to said destination node.

Abstract: A system (105) determines a power level for transmitting to a neighboring node in a wireless network. The system (105) receives a message indicating a three-dimensional position and orientation of the neighboring node and a type of directional antenna of the neighboring node that transmitted the message. The system (105) determines the power level for transmitting to the neighboring node based on the three-dimensional position and orientation of the neighboring node and the type of the directional antenna.

Abstract: The invention relates to methods, apparatus, and software for disseminating link state information in an ad hoc network. The methods, apparatus, and software include an energy conserving processing based on a combination of a multipoint relaying and hazy scoping.

Abstract: The invention relates to communications devices for reduced energy communications in an ad hoc network. The communication device includes a first low-powered transceiver for initiating communications with other communications devices and a second transceiver for transmitting data messages to the other communications devices once communication is initiated. The communication device also includes a communications control processor for determining times at which the other communications devices will be available to receive communications based on scheduling data received from those communication devices. The communications control processor can also take into account requests for reserved bandwidth.

Abstract: A method of communication is provided in which a node maintains a condition table which includes at least one condition unrelated to network traffic conditions, which if met triggers the node to reserve a set of time windows for receiving communications. During those time windows, the node refrains from initiating transmission of communication.

Abstract: A system may place nodes (110) within a non-biconnected network (100) that includes multiple interconnected nodes (110) to achieve biconnectivity within the network (100) and transform the network (100) from a non-biconnected one to a biconnected one. A non-biconnected network is one that necessarily becomes partitioned into two or more disconnected networks if a node in a critical position (termed a “cutvertex” node) should fail or otherwise become unavailable. A biconnected network is one that includes at least one additional network link (sometimes termed an “edge”) between nodes belonging to each of the otherwise potentially disconnected networks for the purpose of maintaining network communication therebetween if and when the cutvertex node fails or otherwise becomes unavailable. To achieve biconnectivity, the system may identify one or more nodes (110) to move and determine the direction and distance to move the one or more nodes (110).

Abstract: A network device (110) includes a forwarding module (230) and one or more network interfaces (240) that may be configured to transmit data units. The forwarding module (230) may be configured to identify one of the network interfaces (240) to transmit a data unit when the data unit is received by the network device (110) or generated by the network device (110), determine one of the network interfaces (240) to transmit the data unit when the data unit is ready to be transmitted by the network device (110), and forward the data unit to the determined network interface (240) for network when the determined network interface (240) is the identified network interface (240).
