ECSM: Energy Efficient Clustering Scheme for Mobile M2M Communication Networks

Scheduling the active and idle period of machine type communication devices (MTC) such as RFID tags, sensors and smart meters are significantly important to achieve energy efficiency in the emerging machine to machine (M2M) communication networks, which comprises thousands of resource constrained MTC devices (i.e., low data rate, energy and bandwidth). However, only a few studies exist in the literature on node scheduling schemes of M2M communication networks. Most of these schemes consider only the energy efficiency of MTC devices and do not support mobility. Thus, we introduce an energy efficient, node scheduling scheme for mobile M2M (ECSM) communication networks. The ECSM scheduling scheme selects a minimum number of active MTC devices in each cluster and increases the probability of network coverage. Simulation results show that the ECSM scheduling scheme outperforms the existing cluster-based and well-known mobility centric LEACH-M and LEACH-ME schemes in terms of network energy consumption and lifetime.
