Abstract: One embodiment of the present invention provides a system for facilitating re-transmitting packets in a communication network. During operation, the system transmits one or more acknowledgments to a neighbor in a designated time slot. Next, the system receives one or more acknowledgments from the neighbor, where a respective acknowledgment confirms that the data packets in a given past time slot have been processed by the neighbor. The system also receives a processed-through-counter (PTC) from the neighbor. Next, the system identifies a time slot up to the time slot indicated in the PTC and which has not been acknowledged by the neighbor. After identifying the time slot, the system re-transmits previously transmitted packets associated with the identified time slot to the neighbor without using a re-transmit timer.

Abstract: Embodiments of a communication system, a method, and a device for use with the communication system are described. Communication between the devices in the communication system may be enabled by the method. In particular, nodes or devices (henceforth referred to as devices) in a network (such as an ad-hoc network) in the communication system may exchange a dynamic network context via communication with neighboring devices. These devices may use the dynamic network context to determine how network resources are shared during the communication, including performing context-aware packet switching of packets (including data packets) in an information flow.

Abstract: One embodiment of the present invention provides a system that communicates a data packet in a network to a target node. In doing so, the system receives a node identifier for the target node, and determines a first positional label, based in part on the node identifier, for reaching a first anchor node from a root node in the network. The first anchor node stores a second positional label for reaching the target node from the root node in the network, which comprises a number of nodes coupled to the root node in a tree topology. The system then retrieves the second positional label from the first anchor node, and communicates the data packet to the target node based in part on the second positional label.
