Design of Real Time Multimedia Platform and Protocol to the Internet of Things

摘要

With the vigorous development of the Internet of Thing (IOT) technology, the wave of the Internet of Things applications followed by. Applications based on IOT real-time multimedia are under the spotlight. However, due to the needs of real-time characteristic, multimedia data often use User Data Protocol (UDP) for transmission which makes packet loss easily happen when there are network congestion and channel noise. What's more, the insufficient upstream network bandwidth among front-end device also restricts the boom of real-time multimedia application. In our paper, we design rational platform architecture to solve the problem of front-end bandwidth. At the same time, we design a new real-time multimedia transmission protocol over UDP. Further more, through NS2 simulation we give a suggestion of the protocol parameter.
