Stability of the discrete-time networked control systems is analysed, where the controller is updated with the buffered sensor information at stochastic intervals and the amount of the buffered data for transmission under the buffer capacity constraint is time-varying. The adopted controller switches between open-loop and closed-loop modes to estimate the plant behaviour. The sufficient conditi...

In this paper, we propose a new approach to exploit buffer caches to upgrade the service capacity of a multimedia on-demand playback system. The basic idea behind exploiting buffer caches is that, if we can relay the data of highly frequently accessed programmes from one access request to another, then we can upgrade the service capacity of the system without requiring higher disk bandwidth. As...

We consider a two-buffer fluid model with N ON-OFF inputs and threshold assistance, which is an extension of the same model with N = 1 in [18]. While the rates of change of both buffers are piecewise constant and dependent on the underlying Markovian phase of the model, the rates of change for Buffer 2 are also dependent on the specific level of Buffer 1. This is because both buffers share a fi...
