Abstract:

In multi-cell scenario, the uneven distribution of machine-to-machine (M2M) terminals seemly leads to problems of system access throughput decrease and user access delay increase. To address these issues, a M2M load balancing algorithm was proposed. The algorithm builds up a model associated with cell signal quality and cell load factor. The problem approximates a convex optimization one, thus realizing load balancing. Simulation shows that, through employment of the proposed algorithm, the performance of access throughput and access delay is improved greatly.
