Cache replacement scheme based on sliding window and TTL for video on demand
(IEEE, 2018-09-25)In this paper, we propose a novel two-phased cache replacement algorithm based on the dataset obtained from a typical wireless mesh network. In the first phase, we aim to make a trade-off between the networks resources and ... -
Cantilever array oscillators with nonlinear optical readout
(IEEE, 2015)MEMS array oscillators typically require a separate detector and feedback loop for each oscillator. We show that grating-based-optical-readout induces nonlinearity, which enables simultaneous operation of an array-of-oscillators ... -
Capacity analysis of free space optical links for a partially coherent gaussian beam over a turbulent channel with pointing errors
(IEEE, 2013)In this paper, we investigate the joint effects of beam width and the spatial coherence length in a partially coherent free-space optical (FSO) link from the information theory perspective, taking into account the combined ... -
Capacity analysis of infrastructure-to-vehicle visible light communication with an optimized non-orthogonal multiple access scheme
