We consider a multi-channel opportunistic communication system where the states of these channels evolve as independent and statistically identical Markov chains (the Gilbert-Elli...
The instability of the tree-like multicast overlay caused by nodes' abrupt departures is considered as one of the major problems for peer-to-peer (P2P) multicast systems. In ...
Dynamic spectrum access is a promising technique to use spectrum efficiently. Without being restricted to any prefixed spectrum bands, nodes choose operating spectrum ondemand. Suc...
