THE STRUCTURAL RELIABILITY OF WIRELESS EPISODIC NETWORKS

Abstract

This paper considers the problem of ensuring the structural reliability of wireless episodic networks with aerial repeaters. The reliability indices of structural-informational and informational connectivities were developed. They take into account simultaneously both structural and functional characteristics of the network, such as: load of the nodes in the network, a way of multiple-access organizing, channels limited bandwidth. An integral index of global packet connectivity, which allows to estimate the reliability of the network as a whole is proposed. A way to improve the reliability of episodic networks based on the optimal placement of aerial repeaters in space has been proposed. It is based on the localization of unmanned aerial vehicles in areas of most problematic sections of the network. Adaptive change in the position of such repeaters in space allows to achieve and to maintain a specified level of network reliability, which is being continuously in progress.
