Title : QoS-aware Spectrum Allocation for Spectrum Sharing Radio Networks
A Spectrum Sharing Radio (SSR) network is introduced as an ‘OFDMA network with user classification’. The user class defines the user’s priority over spectrum. The spectrum allocation problem in a multi-cell SSR network is formulated as a non-cooperative game with each cell acting as a player whose aim is to maximize the number of users who can reach their QoS subject to the premise that users with the highest priority can achieve their QoS. To achieve this, a distributed, QoS-aware and class-aware subcarrier (SC) allocation algorithm is proposed to reach the Nash Equilibrium of the game. Simulation results shows that it can achieve better performance in terms of both throughput and the number of qualified users; particularly important is that it exhibits fast convergence.
