We have already witnessed how mobile and the Apps ecosystem around it has revolutionized our lives. It is expected that soon number of devices/things communicating with each other will grow exponentially (in the form of wearable or sensors or smart home/electronics). Mobile is expected to play an important role in this by acting as the central link of communication as well as an human device interaction medium. Since these devices have limited processing capabilities they needs a HTTP alternative protocol that can keep up with the high volume of communication messages between them efficiently. They need a protocol that is Light weight Reliable Simple Consumes low power Requires low bandwidth.
