Remaining Energy Aware ML-CSMA/TDMA Hybrid MAC Protocol for LTE-M2M Wireless Network

Abstract

One of the major issues that faces the planning of M2M (Machine-to-Machine) networks is the energy consumption, due to battery driven nodes. MTC (Machine Type Communication) is the communication of machine nodes over wireless network to enable IoT (Internet of Things) technology. The expected tremendous usage of this technology during the next few years, will give rise to a massive number of machine nodes served by one base station. The need for a multiple access technique that manages the simultaneous communication between this huge number of nodes and the base station with an energy efficient manner is an urgent issue. In this paper, we design a scalable hybrid energy efficient MAC protocol based on ML-CSMA (Multi-Layer Carrier Sense Multiple Access) concept, which provides an enhancement in the energy consumption with less degradation in the system throughput. The proposed protocol increases the lifetime of the battery-powered nodes.
