Lots of data have to be transferred in the internet of things at high rate. Using spectrum spreaded by LAS multiple access codes and orthogonal subcarriers, spread-spectrum OFDM system integrates both technologies. When it is elaborately designed, the inter-symbol interference and multiple access interference are eliminated to a large extent. In the environment of fading channel, the decision variable of the receiver is given. This kind of wireless or mobile communication system has good performance so that it is very useful in the future application especially in the internet of things.

The study has the method of random multiple wireless access in the networks of the Internet of Things and the control architecture, similar to a software-configured network, examined. The models of collision description, network parameters selection and their initial values, which provide target values for the probability of the delivery in the considered networks, are analyzed. The paper proposes a method the novelty of which lies in the usage of cognitive control of network parameters, taking into account the heterogeneity of conditions for different users with a given probability of data delivery. The proposed method and model of random multiple access and cognitive selection of network parameters are relevant and can be applied when building the access level of the Internet of Things in networks with allowable losses when managing large volumes of heterogeneous traffic and ensuring the required quality of service.

The existing stand-alone multimedia machines and online multimedia machines in the market have certain deficiencies, so they cannot meet the actual needs. Based on this, this research combines the actual needs to design and implement a multi-media system based on the Internet of Things and cloud service platform. Moreover, through in-depth research on the MQTT protocol, this study proposes a message encryption verification scheme for the MQTT protocol, which can solve the problem of low message security in the Internet of Things communication to a certain extent. In addition, through research on the fusion technology of the Internet of Things and artificial intelligence, this research designs scheme to provide a LightGBM intelligent prediction module interface, MQTT message middleware, device management system, intelligent prediction and push interface for the cloud platform. Finally, this research completes the design and implementation of the cloud platform and tests the function and performance of the built multimedia system database. The research results show that the multimedia database constructed in this paper has good performance.

This paper discusses the organisations involved in the development of application standards, European regulations and best practice guides, their scope of work and internal structures. It considers their respective visions for the requirements for future standardisation work and considers in more detail those areas where these overlap, namely human centric or integrative lighting, connectivity and the Internet of Things, inclusivity and sustainability.
