In this paper, we propose signal-centric predictive medium access control algorithms for machine-to-machine communications. In particular, the proposed signal-centric predictive algorithms exploit temporal correlations among sensing results to reduce the total prediction error at the base station. We propose polling algorithms for optimal performance and distributed algorithms for scalability. In addition, we derive analytical results that characterize the polling schedule when the proposed signal-centric predictive polling algorithm is used. Furthermore, we propose algorithms that strike a good balance between prediction error and fairness. Simulation results show that the proposed algorithms significantly reduce the overall prediction error.

In this paper, we propose signal-centric polling-based medium access control algorithms for machine-to-machine communications networks in which the total number of machines is much larger than the total number of channels. To minimize the total prediction error of signals collected at the base station in each time slot, we propose the signal-centric predictive polling algorithm. To mitigate the starvation problem, we propose the weighted signal-centric predictive polling algorithm that strikes a good balance between prediction error and fairness. Analytical and simulation results are included to justify the usage of the proposed algorithms.
