TRIPLEPR-MAC: A Triple Queue Priority Based Medium Access Control Protocol for Wireless Sensor Network



WSN is a network of smart tiny electromechanical devices named sensors.
Sensors perform various tasks like sensing the environment as per its range, transmitting the
data using transmission units, storing the data in the storage unit and performing an action based
on the captured data. As they are installed in an unfriendly environment, recharging the sensors is
not possible every time which leads to a limited lifetime of the network. To enhance the life of a
sensor network, the network requires energy-efficient protocols. Various energy-efficient MAC
protocols have been developed by the research community, but very few of them are integrated
with the priority-based environment which performs priority-based data transmission. Another
challenge of WSN is that most of the WSN areas are delay-sensitive because it is implemented in
critical fields like military, disaster management, and health monitoring. Energy, delay, and
throughput are major quality factors that affect the sensor network.



 In this paper, the aim is to design and develop a MAC Protocol for a field like the military where the system requires energy efficiency and priority-based data transmission.




In the proposed model, a cluster-based network with priority queues is formed that can
achieve higher power efficiency and less delay for sensitive data.



In this research, the simulation of proposed MAC, TMAC and SMAC is done with different
numbers of nodes, same inter-packet intervals, and variant inter-packet intervals. Based on
the script simulation, result graphs are generated.



 The proposed work achieves greater lifetime compared to TMAC and SMAC using priority-based data transmission.
