Embedded wireless networks have largely focused on open loop sensing and monitoring. To address actuation in closed loop wireless control systems there is a strong need to re-think the communication architectures and protocols for reliability, coordination and control. As the links, nodes and topology of wireless systems are inherently unreliable, such time-critical and safety-critical applications...
This paper presents a security-aware topology control scheme for wireless ad-hoc networks. The proposed topology algorithm builds a connected network based on the security level of each node, in the presence of a security threat such as the denial of service attack. The existing topology control schemes are primarily concentrated on optimizing parameters such as the energy consumption, while maintaining...
Several simulation tools are used to evaluate network performance including OMNeT++. In this paper, a case of topology control (TC) in WSNs is simulated by considering its interaction with MAC layer and routing based on the SensorSimulator framework. Some ways to improve the simulation efficiency are described. Finally, the simulation results are given.
In this paper, distributed consensus control is investigated for networks of agents with double integrator dynamics. Two kinds of networks are analyzed, i.e., directed networks with fixed topology and undirected networks with fixed topology and time-delay. For each of the networks, a sufficient and necessary condition is given to guarantee the consensus. It is proved that the largest tolerable time-delay...
