Internet of Things: A survey related to various recent architectures and platforms available

IP-based Internet is the largest network in the world therefore; there are excessive steps towards connecting Wireless Sensor Networks (WSNs) to the Internet. It is popularly known as to IoT (Internet of Things). IETF has developed a suite of protocols and open standards for accessing applications and services for wireless resource constrained networks such as IoT. Development of application requires standardized architecture and platform for design and analysis of new ideas. This paper provides a brief awareness about recent IoT architectures and platforms. It is also discussed some of the gaps issues of the platforms related to usability of the user. This helps researcher to select a particular platform according to need.
