A survey on protocols for internet of things

At present optimization of protocols is a major problem in IoT communication platforms and there are many efforts on the research, analysis and discovery of new solutions related to smart city and high density sensor networks that are used as part of the IoT concept. In addition, other researches make IoT performance lighter and continue to develop it for years. This paper provides a classification of IoT protocols available since architecture IoT was first discovered up to the current trend protocol, there are advantages and disadvantages to the IoT domain. This paper also identifies the main problem protocols that are available in the IoT domain. © 2019 IEEE.
