We introduce a new class of problems called network information flow which is inspired by computer network applications. Consider a point-to-point communication network on which a number ofâ€¦ (More)

Consider a communication network in which certain source nodes multicast information to other nodes on the network in the multihop fashion where every node can pass on any of its received data toâ€¦ (More)

Error correction in existing point-to-point communication networks is done on a link-by-link basis, which is referred to in this paper as classical error correction. Inspired by network coding, weâ€¦ (More)

In the paradigm of network coding, the nodes in a network are allowed to encode the information received from the input links. With network coding, the full capacity of the network can be utilized.â€¦ (More)

In Part I of this paper, we introduced the paradigm of network error correction as a generalization of classical link-by-link error correction. We also obtained the network generalizations of theâ€¦ (More)

We analyze wire-tape channels with secure feedback from the legitimate receiver.We present a lower bound on the transmission capacity (Theorem 1), which we conjecture to be tight and which is provedâ€¦ (More)

Store-and-forward had been the predominant technique for transmitting information through a network until its optimality was refuted by network coding theory. Network coding offers a new paradigm forâ€¦ (More)
