Abstract: Aspects of a method and system for determining and securing proximity information over a network are provided. In this regard, data transmitted over a network may be time-stamped upon entering and/or exiting a network node. By taking the total time to travel between two network nodes and subtracting out any latency internal to one or more intermediate nodes, the time to traverse the physical links (the propagation time) between the two network nodes may be determined. Accordingly, if the speed at which data propagates over each link of the network is known, then a distance from the source node to the destination node may be determined. Additionally, aspects of the invention may enable one or more of authentication, validation, and encryption of timing and/or proximity information transmitted over a network.

Abstract: A network node in a vehicular network processes packets based on a prioritization scheme. The prioritization scheme uses packet type, priority, source, destination, or other information to determine a priority of the packets. Packets can be stored in one of multiple queues organized according to packet type, or other criteria. In some cases, only one queue is used. The packets are time stamped when put into a queue, and a time to live is calculated based on the timestamp. The time to live, as well as other factors such as packet type, packet priority, packet source, and packet destination can be used to adjust a packet's priority within the queue. Packets are transmitted from the queues in priority order. In some cases, the network node can identify a top-priority packet, and transmit the top priority packet without first storing the packet in the queue.
