Evaluation of Packet Concatenation Mechanisms for Low Power Devices in Industrial Internet of Things

Packet concatenation at Media Access Control (MAC) layer has a profound impact for the performance of low power devices in the Internet of Things (IoT), often termed as Wireless Sensor Networks (WSNs). Due to the recent development of enormous packet concatenation schemes, it has become crucial to compare them in order to identify the best method which could fit a specific application scenario for WSN. This paper compares the dynamic duty-cycling based packet concatenation MAC, ADP-MAC (Adaptive and Dynamic Duty-cycle MAC) with concurrent transmission-based MAC primitive PiP (Packet-in-Packet). Simulations have been conducted to compare the single hop performance of 2 schemes based on their Packet delivery Ratio. The detailed implementation for the two protocols has been used for conducting simulation over Avrora emulator. It has been found that ADP-MAC outperforms PiP due to achieving better synchronization between source and sink nodes
