Optimized Channel Utilization in Multi-carrier Wireless Mobile Networks [chapter]

Amrinder Arora, Fanchun Jin, Hyeong-Ah Choi
2006 Lecture Notes in Computer Science  
This paper considers the problem of maximizing throughput in a multi-carrier wireless network that employs predictive link adaptation. The contributions of this paper are the following.  ...  We explicitly consider the time-penalty induced by the transmission-mode changes in wireless networks. We study the trade-offs between the channel-state prediction quality and the throughput.  ...  We have not considered the quality of service requirements for different users in the scheduling problem.  ...
