This paper proposes a multi-objective optimization-based approach to identify critical
elements, including units and interactions within and between systems, in a high-speed train …

In heterogeneous environments, the Internet of Things (IoT) combined with mobile ad hoc
network (MANET), ie, MANET-IoT network, becomes more attractive to end users and …

The foundation of ad hoc networks lies in the guarantee of continuous connectivity.
However, critical nodes, whose failure can easily destroy network connectivity, will influence …

With the characteristics of self-organization and no network infrastructure, Ad Hoc network is
widely used in civil and military communication. Critical node identification is an important …

To monitor and protect Ad Hoc networks more efficiently, it is very necessary to identify
critical nodes in the network. At present, the evaluation of the critical degree of nodes is …

This thesis addresses the problem of network node security from external unethical
processes. It provides a solution in the form of a polynomial time algorithm to find the …
