A study on application layer protocols used in IoT

Abstract

Internet of things is the association of objects connected to the internet that are able to intercommunicate with each other, making everyday life easier, more efficient and cheaper. The current IoT has different vendors each using different standards which allow the devices to communicate to some server in the internet but prohibits it from talking to each other, these silos may hinder the development process of IoT. Providing efficient intercommunication between objects and making appropriate decision based on the data collected for an application is the main challenge of IoT. To achieve this goal couple of protocols are provided by the application layer. The motivation of this paper is the discussion for the need of the common communication protocol that enables all IoT devices to communicate effectively. This survey paper focuses on the most commonly used protocols in the application layer of IoT and their drawbacks.
