The Internet of Things refers to a network of continuously growing objects, including an IP address and the communication between these objects and the systems connected to the Internet. Over the last few years, as a result of the rapid development of the internet of things, a wide range of devices and software that support various communication protocols were developed by the leading companies within the IoT ecosystem. IoT transmission system protocols start at the Layer-3 protocols and end on the application layer protocol. Some of the well-known communication protocols in IoT can be listed as MQTT, Thread, CoAP, Zigbee, and Z-wave. Today, security has become one of the key issues for IoT networks. On the other hand, in most industrial communication protocols such as CANopen, Profibus, and Modbus, due to the application domain requirements, the safety has become critical. Although safety is also a crucial part that needs to be considered in the industrial domain, still there are limited numbers of studies available on the subject. The motivation of this paper is to provide a detailed document that helps to analyze how safety transmission should be handled for IoT communication protocols. In this paper, threats such as repetition, deletion, insertion, re-sequence, corruption, delay and masquerade for IoT networks and possible techniques to deal with these threats are discussed and at this point, a road map is presented about the methods that should be applied to make safe the IOT communication protocol.
