Study of Application Layer Protocol for Real-Time Monitoring and Maneuvering

The motes in the sensor network with having low processing capability and limited storage space combined to form a tiny smart sensor with the restricted power source cannot be directly used as things in the present network of an Internet of things. Millions of different devices placed anywhere at any time performing any job can be connected, and transfer of data can be established in the Internet of things. In a network of billions of devices connected together, security of data transmitted can only be provided if the protocol at the application layer is lightweight to be accessible by tiny motes. Application layer comes at the top of the TCP/IP heap. In this chapter, two major protocols of application layer HTTP and MQTT have been discussed and tested with a real-time operated hardware module with the capability to Internet connectivity. The arena for testing both the protocols consists of the transmission and reception of data in the network of tiny motes connected with the network of the Internet.
