Energy Efficient MAC protocols for Green IoT: A survey

Abstract

As Internet of Things expands quickly, there is growing need for energy efficient communication protocols to guarantee long term sustainable network operations. There are number of devices connected to the IoT systems is increasing per day with technological enhancements. To focus on sustainable environmental development, the concept of green IoT is flourishing and procedures adopted for IoT should be energy convergent. The developments in enabling energy-efficient MAC protocols for green IoT are examined in this paper. It groups different MAC protocols on techniques like duty cycling, adaptive listening, and wake-up radio, according to how they use less energy. It also talks about the trade-offs between network scalability, latency, and energy efficiency. In order to improve performance of the system, the devices should be energy efficient. The review aims to provide insights into designing sustainable MAC protocols that support low-power, high-performance IoT MAC protocols. This paper analysis various current protocols for Mac layer that suggests ways to enhance energy efficiency.
