Communication complexity of computing functions using unrestricted communication and one-round communication are compared. In the standard unrestricted communication each party could potentially communicate several times while in one-round communication each party is restricted to communicate at most once. Results on the ratio of these two complexities are provided for symmetric and asymmetric functions...
We propose a mechanism for reliable broadcasting in wireless networks, that consists of two components: a method for bandwidth efficient acknowledgment collection, and a coding scheme that uses acknowledgments. Our approach combines ideas from network coding and distributed space time coding.
An Introduction to Network Coding Network coding is an emerging area that re-examines fundamental principles of network information flow. The main idea is that we allow intermediate nodes in a network to not only forward but also to process the incoming information flows. The network code is the set of the operations that intermediate nodes perform. This simple idea promises to have a significant...
