Patent number: 8406175Abstract: This invention relates to systems and methods for communication in a wireless ad hoc network that employs multi-packet reception. The wireless network includes a transmitting node configured to transmit a control packet to a receiving node while other nodes within a transmission range of the transmitting node are involved in ongoing communication. The receiving node is configured to receive the control packet while simultaneously receiving a second packet from a second transmitting node, and to process the control packet without aborting the receiving of the second packet. Methods for transmitting and receiving multiple packets simultaneously are also presented.Type: GrantFiled: February 19, 2010Date of Patent: March 26, 2013Assignee: Raytheon BBN Technologies Corp.Inventors: Cesar A.

Patent number: 8175016Abstract: Systems, methods and computer readable media consistent with the present invention address this and other needs by providing mechanisms for minimizing an energy cost within a wireless network having a plurality of nodes, including a plurality of transmitting nodes and a plurality of receiving nodes. An energy cost, including at least an overhearing cost, is determined. A transmission power assignment of a transmitting node is then adjusted to reduce the energy cost. These determining and adjusting stages are repeated to reduce the energy cost.Type: GrantFiled: March 19, 2004Date of Patent: May 8, 2012Assignees: Verizon Corporate Services Group Inc., Raytheon BBN Technologies Corp.Inventors: Prithwish Basu, Jason Keith Redi

Patent number: 8166204Abstract: 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).Type: GrantFiled: August 29, 2003Date of Patent: April 24, 2012Assignee: Raytheon BBN Technologies Corp.Inventors: Prithwish Basu, Jason Keith Redi

Patent number: 8149733Abstract: In many aspects, the invention relates to systems and methods for synchronizing a communication network, particularly a slotted communication network, having a plurality of nodes. In slotted communication networks, the nodes are configured to transmit or receive data during selected time slots. During a selected time slot, each node transmits a synchronization message that is received by a neighboring node. The neighboring node adjusts its time slot boundary to coincide with the time of receipt of the synchronization message, thereby synchronizing each node with a neighboring node. Such systems and methods are energy efficient, accurate, fast, fault tolerant and easy to implement.Type: GrantFiled: August 24, 2007Date of Patent: April 3, 2012Assignee: Raytheon BBN Technologies Corp.Inventors: Prithwish Basu, Lillian Lei Dai, Jason Keith Redi, William Nii Tetteh

Patent number: 8145201Abstract: 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.Type: GrantFiled: May 22, 2006Date of Patent: March 27, 2012Assignee: Raytheon BBN Technologies Corp.Inventor: Jason Keith Redi

Patent number: 8103792Abstract: 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).Type: GrantFiled: October 8, 2009Date of Patent: January 24, 2012Assignee: Raytheon BBN Technologies Corp.Inventors: Mitchell P. Tasman, Jason Keith Redi, Richard Dennis Rockwell
