Abstract: A method and system for a Wireless Resilient Routing Reconfiguration linear program or protocol (WR3LP). The WR3LP provides a routing protection scheme that is (i) congestion-free or reduced congestion under a wide range of failure scenarios in point-to-multipoint networks, (ii) efficient in terms of router processing overhead and memory requirement in wireless and point-to-multipoint networks, (iii) flexible in accommodating diverse performance requirements in wireless and point-to-multipoint networks (e.g., different traffic protection levels), and (iv) robust to traffic variations and topology failures in wireless and point-to-multipoint networks.

Abstract: A mobile infrastructure assisted ad-hoc network increases the number of nodes capable of being serviced by the network by selectively choosing those protocols for selected nodes which minimize overhead with the freed up bandwidth permitting an increase in the overall number of nodes serviceable by the ad-hoc network to as many as 1,000 nodes. In one embodiment node dynamicity is determining factor as to what protocol will be used.

Abstract: A system and method for transmitting encoded data in a network is presented. The method begins with a source node of a network encoding a first generation of data using linearly-independent encoding vectors to produce an encoded first generation. Next, packets containing the encoded first generation are created. The packets are then transmitted over a subgraph of nodes with multiple paths to a destination node. A determination is made at a receiving node that an insufficient amount of packets of the encoded first generation have been received in order to decode the encoded first generation. A repair request is sent from the receiving node to nodes upstream to indicate a need for more packets of the encoded first generation without specifying a particular packet. In response to the repair request, at least one node upstream from the receiving node sends a packet with encoded first generation data.
