Abstract: When the M2M devices communicate with each other within a group or cluster without any human intervention, this is called inter-M2M communications. Hence, there is a critical requirement of a scalable medium access control (MAC) protocol to enable multiple M2M devices to access the channel. For this purpose, contention or reservation-based MAC protocols can be used, but with multiple M2M devices, adaptability, and scalability become bottlenecks. Therefore, in this paper, we propose a novel hybrid-MAC protocol, which mainly consists of a contention interval (CI), and a data transmission interval (DTI). During CI, all the active M2M devices contend for the channel access. After contention, the successful devices win time-slots in DTI. The M2M devices are enabled with another proposed high throughput MAC (HT-MAC) protocol, and share data with each other within each time-slot during DTI. Simulation results show significant per time-slot throughput improvement as compared to IEEE 802.11 MAC protocol.
