ABSTRACT:
Medium Access Control (MAC) protocol consists of sets of rules that
determine which node is allowed to access the transmission medium. It provides
mechanism for collision avoidance such that interfering sensor nodes do not
transmit at the same time. In the literature, researchers have proposed
different MAC protocols with features aimed at improving energy efficiency and
thereby prolonging the life of sensor nodes. Sensor MAC, Time-out MAC (T-MAC),
Dynamic Sensor MAC (DSMAC), WiseMAC, Quorum-based MAC (Queen-MAC) and Traffic
Adaptive Medium Access Protocol (TRAMA) are some examples of proposed MAC
protocols. There is a duration field in each transmitted packet. The value of
this field indicates how long it will take to complete the remaining packet
transmission. In the current paper, a novel energy-efficient MAC protocol is
proposed based on the use of duration value in transmitted packets to setup varying
sleep/wake-up schedules for neighbouring nodes of the receiver. The effectiveness
of this proposed Packet-Duration-Value-based MAC (PDV-MAC) protocol is
tested via Simulation which is implemented in Visual C# and MATLAB. It is shown
by the results obtained that the proposed MAC protocol can indeed be
implemented in sensor nodes to improve energy efficiency in wireless sensor
network.
