OFDMA has been selected as the multiple access scheme for emerging broadband wireless communication systems. However, designing efficient resource allocation algorithms for OFDMA systems is a challenging task, especially in the uplink, due to the combinatorial nature of subcarrier assignment and the distributed power budget for different users. Inspired by Glauber dynamics, in this paper, we propose...
The grid technology enables large-scale sharing and collaboration use of networked resource. Using P2P technology, grid system can have better scalability and dynamic. OGSA provides a framework for integrating P2P technology into grid system. However, grid resource discovery is a key issue for P2P grid. In this paper, a novel model based on P2P technology, is proposed to discovery grid resource efficiently...
