Wireless sensor network is a distributed network of
large number of sensor nodes having capability to sense the
physical conditions of environment or system. Energy efficiency
is the main concern in WSN due to sensor nodes' limited battery
power. Reasons for energy wastage during communication in
WSN are collision, overhearing, control packet overhead and
idle listening. Task of MAC protocol is to coordinate the times
that several sensor nodes access a shared communication
medium. One of primary mechanisms for achieving low energy
consumption in WSNs is duty cycling. In this approach each
node periodically cycles between awake state and sleep state.
Here, a review on the various duty cycling based MAC protocols
in WSN is carried out.

Energy efficiency is the main concern in WSN due to
sensor nodes' limited battery power. Task of MAC
protocol is to coordinate the time that several sensor
nodes access a shared communication medium. One of
primary mechanisms for achieving low energy
consumption in WSNs is duty cycling. This paper
discusses and compares some duty cycling based MAC
protocols.
