Wireless Sensor Network Connectivity in Heterogeneous 5G Mobile Systems

In this paper we perform the analysis of connectivity of wireless sensor network in heterogeneous 5G mobile systems. Wireless sensor networks are an important part of modern heterogeneous 5G mobile systems and IoT networks. The architecture, principles of organization of wireless sensor networks and their connectivity are investigated in the paper. The peculiarity of networks with mobile nodes is the alteration of conditions of radio signals propagation, which leads to random structures of such networks. Connectivity in networks with mobile nodes is their paramount characteristic and it is necessary for the functioning of the network. The analysis of the dependence of connectivity on the network parameters has been carried out in the paper. It is shown that connectivity is determined by the probability of a route for any network node. In addition, connectivity is a measure of the relationship between any sensor node and the data processing and storage center. Three algorithms for cluster analysis of the wireless sensor networks have been suggested in the research. They include algorithm of clustering of k-means, algorithm of the Foreign element fuzzy C-means algorithm. The quality parameters of the network connectivity have been analyzed. The main indicators of network connectivity, which include availability indicators, time indicators and reliability indicators, are discussed.
