Abstract
Prolonging the lifetime of sensor nodes is still a challenging area of research in wireless sensor networks (WSNs) and other related wireless communication technologies. WSNs have numerous extensive research works, which are dedicated to design energy-efficient MAC protocols. WSNs have wide range of applications that cover various fields such as surveillance, defense, and healthcare. The WSNs can become an invaluable resource for realizing the vision of the Internet of thing (IoT). The integration of WSNs and IoT can easily solve countless difficult problems and make the life easy. This paper proposes a dynamic duty cycle MAC (D2CMAC) protocol, which emphasizes mainly on accomplishing less energy consumption with acceptable packet loss and latency. The D2CMAC protocol attempts to increase the sleep interval, while data traffic is very low that leads to consuming less energy as compared to SMAC and tunableMAC (CSMA/CA with duty cycle) protocols. The simulation results illustrate that D2CMAC consumes less power of battery up to 57% and 9%, when compared with SMAC and tunableMAC protocols, respectively.
