A study of Conventional Protocols applicable to the emerging IoT Systems and Devices

The era of development of intelligent machines has led to automation at such a level a combination of artificial intelligence and self-operating gadgets are over taking the manual operations. Further, the integration of such intelligence with Internet has extended the horizons of development and research to a new level and has led to development of Internet of Things (IoT) devices. Self-decision-making in-home appliances will make them smart appliances such as smart refrigerators, smart televisions, washing machines and dish washers, smart ACs, etc and are incorporated as "THINGS" in IoTs. Although this development is finding its way to new peaks but the protocols, methodologies and ethics of intercommunication of smart devices is still a work of art for researchers. This paper tends to provide an overview of various protocols of data transmission that are providing possible solutions to various problems that may be faced in secure data transmission, integration and manipulation of data for efficient decision making of smart machines and appliances placed remotely or locally. A comparison of various parameters such as operating frequency, range and data rate has been presented to analyze various technologies for various applications.
