Wireless sensor networks have become an active research area for the researchers. Several researchers in Wireless sensor networks have led to many new protocols specifically designed for different kinds of applications where reliability and energy efficiency is an essential consideration. Most of the attention has been given to the Medium Access Control (MAC) protocols since they pay an important role in wireless communications and traditional MAC protocols are not suitable for Wireless sensor networks. The aim of the paper is to study the Reliable and energy efficient Medium Access Control (MAC) protocols design approach for wireless sensor network and to motivate the researcher, while showing the future aspects in the area of Wireless Sensor Networks.
