Distributed rate and admission control in home M2M networks: A non-cooperative game approach

It is envisioned that home networks will shift from the current machine-to-human communications to the machine-to-machine (M2M) paradigm with the rapid penetration of embedded devices in home surroundings. In this paper, we first proposed an architecture of home M2M networks that is decomposed into three sub-areas depending on the radio service ranges and potential applications. We then concentrate on the Quality-of-Service (QoS) management in home M2M networks. Although generic QoS architectures for home M2M networks have been proposed in existing standards, the concrete QoS schemes and algorithms are still missing. Based on the proposed architecture, a cross-layer design of distributed admission and rate control is put forwarded. This proposed scheme, named DRAC, is integrated with a game theory analysis module to model the competition of radio bandwidth among M2M home devices, and embrace the distributed operations of QoS-aware and fair sharing in transmission opportunities. Simulation results indicate that the proposed DRAC scheme allows the M2M home devices to intelligently share the radio bandwidth based on QoS demands in resource-constrained home M2M networks.
