Embodiment 1
[0189] Based on the simulation parameters in Table 1, this embodiment simulates the cloud-based Internet of Things multimedia data communication method in the present invention, and the performance analysis is as follows: when the user is far away from the destination node, the average communication cost and delay will also increase. When the communication radius increases, the average communication cost and delay decrease accordingly. The average communication cost is 7, and the routing delay is 65ms.

The invention provides an Internet of things multimedia data communication method based on cloud. The Internet of things comprises two kinds of nodes: basic facility nodes and equipment nodes; the basic facility nodes comprise access routers, switches and access nodes, and are used for achieving route forwarding functions; the equipment nodes are used for sensing and collecting data related to geographical locations, converting the data into a multimedia data form, and the equipment nodes do not have the route forwarding function. According to the method, multimedia data communication can e quickly achieved, quality of service can be improved; and the method provided by the invention can be widely applied to fields of environment monitoring and road traffic management.
Description
