We introduce the (private) entropy of a directed graph (in a new network coding sense) as well as a number of related concepts. We show that the entropy of a directed graph is ide...
—Slepian-Wolf coding is a promising distributed source coding technique that can completely remove the data redundancy caused by the spatially correlated observations in wireless...
While it is well known that network coding achieves optimal flow rates in multicast sessions, its potential for practical use has remained to be a question, due to its high compu...
Multimedia (e.g., video) information exchange in VANET, if feasible, will help enhance vehicle navigation safety. We show that network coding allows very reliable and efficient d...

Sensor network operating systems have to operate with limited hardware resources. Constraints on power consumption greatly reduce the resources available to such an operating syst...
