This paper targets the problem of optimal resource allocation in overlay multicast, which poses both theoretical and practical challenges. Theoretically, resource allocation among...
—In this paper, the IEEE 802.16 protocol is investigated with respect to the bandwidth provision problem arising at the Medium Access Control (MAC) layer. The aim is to optimally...
— Cooperative diversity obtains the spatial diversity gains created by sharing antennas of terminals in wireless networks. In this paper, adaptive amplify-and-forward (AF) cooper...
