Abstract
In Wireless Sensor Networks (WSNs), the Media Access Control (MAC) layer is
responsible for coordinating Sensor Nodes (SNs) as their access to the media. Real
time data flow needs precise scheduling for sensor nodes to access the medium in order
to send the data on time. Time slotted transmission scheduling is needed to access
the media without collision. To achieve this, sensor nodes need to be synchronized
and know about each other’s notion of time. However, time synchronization requires
message exchanges, which incur high overhead. The proposed MAC protocol, which
consists of algorithms that minimizes collision and detects hidden terminals, eliminates
the message overheads of global time synchronization
