Abstract

Abstract - In this paper authors have elaborated on objective of MAC protocol, energy efficiency of MAC protocol and comparison of MAC layer protocols such as S - MAC and D - MAC for WSNs. The primary goal of the S - MAC design is to improve energy efficiency while maintaining good scalability and collision avoidance. To achieve this goal, S - MAC tries to reduce energy consumption from all the major sources that causes inefficient use of energy. D - MAC protocol was proposed to address the data forwarding interruption problem in multihop data delivery and its primary goal is to achieve both energy efficiency and low latency. Authors have tried to explain how D-MAC is more energy efficient than S-MAC and also elaborated on how performance of D-MAC can be improved using single or multiple mobile element based data gathering Technique.
