An efficient channel allocation scheme for multicast traffic in multitier cellular systems

Abstract

In this letter, we propose an efficient channel allocation scheme to provide multicast traffic in multitier cellular systems. Our proposed scheme allocates microcell/macrocell channels based on the 'microcell-group size' and probability. Also, we analyze the performance of the scheme in view of the call blocking probalility in case of considering overflow traffic or not. Numerical results show that our proposed scheme exhibits: a better performance than conventional schemes.
