%X 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.
