Energy Efficient Synchronous Media Access Control for Wireless Sensor Networks

摘要

The technological advancements have brought a revolution in the field of communication, especially in the area of wireless communication. It has made the deployment of WSNs possible which comprise of a large number of low-power and low-cost sensor nodes to perform the task of sensing, processing, and communication. WSNs set stringent requirements for network lifetime, resource constraint, application specific behavior and they are highly dynamic in nature. The one factor which affects the most is the network lifetime and it requires the energy efficient operation to be performed. This article aims at providing researchers a clear understanding and deep insight into the selection MAC protocols which is one of the major design factor while establishing WSNs or developing an energy efficient routing protocol for WSNs. The article presents a systematic review of various low duty cycle syncronous MAC protocols along with an in-depth analytical comparison and discussion based on various performance metrics.
