Simplified SIP Approach for the Smart Object

To achieve the Smart Object world, we need to create appropriate application layer protocols. We consider high extensibility and applicability for human-to-machine type communications as well as machine-to-machine are especially needed for the protocol design of the application layer protocol. Those characteristics are important to support new devices, applications and type of communications which will form the future Smart Object world as well as currently envisioned ones. In this paper, we show that SIP (Session Initiation Protocol) fulfills these requirements of the protocol design and it is suitable for the Smart Object. On the other hand, it is shown SIP lacks lightweightness, which is also one of the most important requirements for the Smart Object. To bring significant sustainability into the Smart Object world by using SIP, we propose “simplified SIP approach” for improving SIP lightweightness and remark the future works in this approach.
