Various dynamic MAC layer approaches have been adopted by researchers for achieving better performance of Wireless Sensor Networks (WSNs). Some of these approaches include Dynamic Duty-Cycle (DDC), multi-channel parallel transmissions, Dynamic Channel Polling (DCP) and adaptive traffic rate adjustments. This work provides a comparative analysis of the two schemes 'dynamic duty cycle' and 'dynamic channel polling' by comparing two protocols T-AAD and ADP-MAC taken as a representative protocol from each category respectively. Avrora simulator has been used for conducting experiments on mica-2 testbed, and energy & delay performance for the two schemes has been compared. Results have revealed that ADP-MAC outperforms T-AAD by reducing the transmission energy and latency, and hence it is more suitable for emerging applications of WSN & IoT.
