Software Defined Network architecture model and cognitive control method for organizing multiple access in the Internet of Things

Abstract

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.
