NETWORKING PROTOCOLS AND STANDARDS FOR INTERNET OF THINGS

This chapter highlights Internet of Things (IoT) protocols that are operating at different layers of the networking stack, including Medium Access Control (MAC) layer, network layer, and session layer. Generally, the most widely used standards in IoT are Bluetooth and ZigBee. IEEE 802.11ah, on the other hand, is the easiest to be used due to the existing and widely separated infrastructure of IEEE 802.11 which is the most used infrastructure in other wireless applications. The chapter discusses some standard and non‐standard protocols that are used for routing in IoT applications. Low‐Power and Lossy Networks (RPL) is the most commonly used routing protocols in IoT. Cognitive RPL (CORPL) is a non‐standard extension of RPL that is designed for cognitive networks. Security is an aspect of IoT applications which is critical and can be found in all almost all layers of the IoT protocols. The chapter also discusses the security mechanisms built in the IoT protocols.
