The problem of multiple multicast sessions with intra-session network coding in time-varying networks is considered. The network-layer capacity region of input rates that can be stably supported is established. Dynamic algorithms for multicast routing, network coding, power allocation, session scheduling, and rate allocation across correlated sources, which achieve stability for rates within the capacity...
Network coding is a promising generalization of routing which allows a network node to generate output messages by encoding its received messages to reduce the bandwidth consumption in the network. An important application where network coding offers unique advantages is the multicast network where a source node generates messages and multiple receivers collect the messages. Previous network coding...
We consider the problem of exchanging packets from the individual queues at multiple wireless terminals with the assistance of a single relay node. In an earlier paper, we studied this for a backlogged traffic model, where each node always had packets to transmit. Here, we consider stochastically varying packet traffic and compare the stable operation under plain routing, and digital and analog network...
The advent of various real-time multimedia applications in high-speed networks creates a need for quality of service (QoS) based multicast routing. Two important QoS constraints are the bandwidth constraint and the end-to-end delay constraint. The QoS based multicast routing problem is a known NP-complete problem that depends on (1) bounded end-to-end delay and link bandwidth along the paths from...
