In this paper, we consider robust stability analysis of a networked system with uncertain communication delays. Each subsystem of these systems can have different dynamics, and interconnections among the subsystems are arbitrary. It is assumed that there exists an uncertain but constant delay in each communication channel. Based on the integral quadratic constraint (IQC) framework, a sufficient robust...
Cognitive radio significantly mitigates the spectrum scarcity for various applications built on wireless communication. Current techniques on mobile cognitive ad hoc networks (MCADNs), however, cannot be directly applied to time-critical applications due to channel interference, node mobility as well as unexpected primary user activities. In multichannel multiflow MCADNs, it becomes even worse because...
Channel interference and node mobility cause significant performance degradation to wireless networks. In multichannel multi-flow mobile cognitive ad hoc networks, it becomes even worse due to both unexpected primary user activities and potential interference among multiple flows. In this paper, we propose a Joint Routing and Channel Assignment (JRCA) approach based on delay prediction. Firstly, it...
