Abstract: Some embodiments are directed to a computer-assisted method for identifying a vehicle. The computer-assisted method can include: receiving, from a stationary sensor, sensor data representing a plurality of moving vehicles; receiving, from a particular vehicle, a communication including sensor data representing the particular vehicle, wherein the sensor data includes at least one of velocity and position for the particular vehicle; and identifying, from the sensor data representing a plurality of moving vehicles, a subset of the data representing the particular vehicle, wherein identifying the subset of data comprises analyzing the sensor data received from the stationary sensor in conjunction with the sensor data received from the particular vehicle.

Abstract: One aspect of the invention provides a theft detection system including one or more tag nodes configured to detect movement and transmit a beacon message and one or more anchor nodes configured to receive the beacon message from the one or more tag nodes and alert a third party of the beacon message. Another aspect of the invention provides a theft detection node including a power source, a motion detector, a transmitter, and a microcontroller in communication with the power source, the motion detector, and the transmitter. The microcontroller is configured to determine whether the node is being transported and if the node is being transported, instructing the transmitter to transmit a beacon message. Another aspect of the invention provides a theft detection method including detecting motion in a motor vehicle and transmitting a beacon message to an anchor node.

Abstract: A network node computes a fair share data rate for the sharing of a shared communication channel in a local area network. The network node determines the required information for computing the fair share by snooping the network, by receiving the required information from other network nodes, or a combination of the two techniques. Alternatively, instead of computing the fair share data rate, the network node may receive the fair share data rate which was computed by another network node. The fair share data rate is enforced by the network node in a network protocol stack layer above the media access control layer. In one embodiment, the network protocol stack layer above the media access control layer is the link layer.

Abstract: The present invention provides a method and apparatus for extending a zone routing protocol. The invention is configured to provide a robust scalable framework for routing data in wireless ad-hoc networks when unidirectional links 210 are present. When the reverse path from a destination node (the tail) of a unidirectional link 210 to the originating node (the head) of the link is beyond a designated length, the invention is configured to revert to an on-demand search mechanism. The on-demand search mechanism recursively attempts to build a path to the destination 206 by recognizing nodes that have a route to the destination.
