Limited bandwidth and high packet loss pose a serious challenge for video streaming over wireless networks. Even when packet loss in the medium is not present, the fluctuating ava...
Cognitive radios permit dynamic control of physical layer resources such as transmission power and constellation size; these degrees of freedom can be employed to achieve significa...

Abstract. The paper proposes a priority-aware MAC (Medium Access Control) protocol for a core metropolitan area network in the next generation Internet, which is an OPS (Optical Pa...
Since wireless ad-hoc networks use shared communication medium, accesses to the medium must be coordinated to avoid packet collisions. Transmission scheduling algorithms allocate ...
