IOT Platforms: a Brief Study Chaitra Acharya M.Tech Student, National Institute of Engineering, Mysuru, India
International Journal of Advanced Research in ISSN : 2347 - 8446 (Online) Computer Science & Technology (IJARCST 2016) Vol. 4, Issue 2 (Apr. - Jun. 2016) ISSN : 2347 - 9817 (Print) IOT Platforms: A Brief Study Chaitra Acharya M.Tech Student, National Institute of Engineering, Mysuru, India Abstract Internet is one of the most important and powerful creations in all of human history. The internet is basically an informal term for the world-wide communication network of computers more specifically called the network of networks. Internet not only links computers but also people through them. It was primarily designed to share information between networks. In today’s world people use internet for a variety of reasons: from browsing for information to chatting and even online services like shopping, banking, video conferencing and so forth. As the years progress, the services provided by the Internet grows endless. The “Internet of Things” refers to the concept that the Internet is no longer just a global network for people to communicate with one another using computers, but it is also a platform for devices to communicate electronically with the world around them. IoT represents the next evolution of the Internet, taking a huge leap in its ability to gather, analyse, and distribute data that we can turn into information, knowledge, and, ultimately, wisdom. There are a variety of IoT platforms like Thingspeak, Grovestreams, Thingworx, Xively and so on which provide IoT services to the users for a price. Keywords Internet of Things, IoT Architecture, Web of Things, Thingspeak, Grovestreams, Thingworx. I. Introduction we will discuss options for realizing each component. -

In a networked scenario organisations often need several people (may be at different locations) to input and process data simultaneously. In order to achieve this, a computer-networking model in which a number of separate but interconnected computers do the job has replaced the earlier standalone-computing model. By linking individual computers over 4 7 Network Fundamentals a network their productivity has been increased enormously. A most distinguishing characteristic of a general computer network is that data can enter or leave at any point and can be processed at any workstation.
