Poster: Comparative study of EM MAC and TSCH/orchestra for IoT
Multichannel Medium Access Control (MAC) protocols for IoT can potentially improve network performance. Therefore, a considerable number of such protocols have been proposed in the last decade, ranging from slotted synchronous to contention based asynchronous multichannel protocols. In this paper two of the most representative multichannel MAC layer protocols are compared: Time Slotted Channel Hopping (TSCH) using the Orchestra scheduling algorithm, and Energy Efficient Multichannel MAC (EM MAC) The performance of these protocols is assessed under different traffic loads and node densities using the standard IPv6 Routing Protocol for Low Power and Lossy Networks (LLNs) i.e. RPL. The results show the cross layer interaction between the RPL protocol and the multichannel MAC schemes under study. Moreover, it can be generally appreciated that TSCH/Orchestra performs better in terms of Packet Delivery Ratio (PDR) whereas EM MAC exhibits lower power consumption. These characteristics reveal the suitability of these protocols for different IoT applications.
