Executive Summary

The femtocell system is an efficient solution to increase the wireless systems coverage. However, femtocells may experience spatially diverse interferences. A proper exchange on the channels between femtocells can improve the transmission experience. The authors proposed game-theoretical DANCE mechanism to derive the optimal allocation in the femtocell channel allocation problem. The simulation results showed that DANCE mechanism can enhance the channel allocation efficiency significantly. Increasing the system capacity of a wireless link is one of the most important issues nowadays. For wireless technologies using high-frequency spectrum such as 3G, WiMAX and LTE, their signals degrade significantly in indoor environments.
