Comparison Analysis of MAC Protocols for Wireless Sensor Networks

Abstract

Wireless sensor networks (WSN) are rapidly emerging as an interesting and challenging area of research in the field of communication engineering. This review work is different from other state-of-the-art literature as the MAC protocols discussed here are applicable both for homogeneous and heterogeneous networks. Performances like energy efficiency, cost optimization, throughput, bandwidth utilization, and scalability of the sensor network depend on MAC protocols, which are application-based. In the study, the authors have surveyed different MAC protocols with different merits and demerits. Based on the study, it is very hard to recommend any particular protocol as a standard for implementation as these are exclusively application dependent. The work can be further extended in terms of hybrid protocols, which may carry the advantages of the respective protocols along with energy-efficient criteria for practical implementation. Further cooperative WSN communication can be used for internet of things (IoT)-based systems, where the node placements and multi-operations concepts are of main concern.

Development of Recovery and Redundancy Model for Real Time Wireless Networks

“…The probability of correct delivery of frames before deadline by station can be expressed using Equation ( 6): (6) where the probability of a frame of station failing on the attempt is given in Equation ( 7):…”

“…In wireless networks, media access control (MAC) protocols like carrier-senses multiple access with collision avoidance (CSMA/CA), multiple access with collision avoidance (MACA) are liable to contention and collisions because of different attempting stations to access the medium the same time [6] . Hence, TDMA channel access approach provides collision and contention-free medium access.…”
