Abstract

Abstract:

This study focuses on the massive device characteristic of M2M communication. Considering the overload situation in H2H&M2M co-existence scenario of OFDMA cellular networks, we propose an admission control and resource allocation joint optimization algorithm. Considering the effect of control channel, we formulate a MINLP problem of maximizing the number of MTCDs admitted. Because of the complexity of MINLP problems, relaxed constraints are used to transform the MINLP problem into a convex problem, which is the upper-bound of the original problem. Furthermore, a low-complicity algorithm is proposed. Simulation results show that the algorithm has minor degradation compared with the upper-bound and is better than two other algorithms.

Key words: M2M, admission control, resource allocation, control channel
