Proposed Energy Effiiciient Mulltii-Layer MAC Protocoll for Massiive MTC over LTE Wiirelless Network

Energy efficiency is one of the prime consideration in designing Machine Type Communication (MTC) networks, because of the battery-powered machine nodes. Therefore, extending the network lifetime can be done by using more energy efficient techniques. The dramatically increase in the number of machine nodes in many aspects of our life makes the wireless standards to adopt Machine to Machine (M2M) communication in its new specifications. The massive number of machines need a new MAC protocol that makes full use of the node’s battery, so that node can live longer time. In this paper, a new protocol called Multi-Layer MAC (ML-MAC) will be suggested, and then integrating this protocol into LTE network will be made. Calculations of energy efficiency, delay, and throughput as a performance parameter will be done. Simulation results show that proposed ML-MAC protocol is more energy efficient compared to traditional IEEE 802.11 MAC protocol and Sensor MAC (S-MAC) protocol. Moreover, prolonging the network lifetime can be done by using the new ML-MAC protocol than others.
