Abstract: 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.
