	abstract = {<p class="rtejustify">Automatic restoration of control wireless networks based on dynamic\&nbsp;cyber-physical systems has become a hot topic in recent years, since most of their\&nbsp;elements tend to have serious vulnerabilities that may be exploited by attackers.\&nbsp;In fact, any exploitation may rapidly extend to the entire control network due to\&nbsp;its problem of non-locality, where control properties of a system and its structural\&nbsp;controllability can disintegrate over time. Unfortunately, automated self-healing\&nbsp;processes may become costly procedures in which the reliability of the strategies\&nbsp;and the time-critical of any recovery of the control can become key factors to\&nbsp;re-establish the control properties in due time. This operational need is precisely\&nbsp;the aim of this paper, in which four reachability-based recovery strategies from\&nbsp;a thereotical point of view are proposed so as to find the best option/s in terms\&nbsp;of optimization, robustness and complexity. To do this, new definitions related to\&nbsp;structural controllability in relation to the type of distribution of the network and\&nbsp;its control load capacity are given in this paper, resulting in an interesting practical\&nbsp;study.</p>
