Joint congestion control and scheduling has been widely applied to resource allocation in multi-hop wireless networks. Existing algorithms usually rely on seamless cooperation between network components to seek the optimal solution. However, this is unrealistic considering the presence of time delay and channel capacity perturbation in real wireless environments. The stability and efficiency of these...
Wireless Networked Control Systems (NCS) are increasingly deployed to monitor and control Cyber-Physical Systems (CPS). To achieve and maintain a desirable level of performance, NCS face significant challenges posed by the scarce wireless resource and network dynamics. In this paper, we consider NCS consisting of multiple physical plant and digital controller pairs communicating over a multi-hop wireless...
Building networked control systems over wireless networks is an extremely challenging task, as the wireless communication characteristics such as random packet losses and delay, significantly affect the stability and the performance of the control systems. We present a novel approach to the design of wireless networked control system. This approach decomposes the design concerns into two factors and...
Joint session scheduling (JOSCH) enables traffic to be split and transmitted over multiple radio access networks (RANs) simultaneously, which improves the quality-of-service (QoS) in terms of transmission rate, reliability and stability. Transmission synchronization is one of the key issues which JOSCH should consider, as it has direct effect on the performance of buffer management and data reassembly...
Recent advances in wireless sensor technology facilitate the development of remote healthcare systems, which can significantly reduce the healthcare cost. Despite the initial promising results, there remain many obstacles to apply this technology to the practical medical care context. One of the critical issues is to assure the timely and robust delivery of the life-critical medical data in the resource-constrained...
In this paper, we propose a novel hybrid optical network design method, cycle-based hybrid switching optical networks (CHSON), to efficiently support bursty traffic patterns of current networks. CHSON integrates highly efficient transportation of optical circuit switching with statistical multiplexing of Optical burst switching. CHSON could not only reduce the strain on packet forwarding of traditional...
