A detailed examination of evolving traffic characteristics, operator requirements, and network technology trends suggests a move away from nonblocking interconnects in data center networks (DCNs). As result, recent efforts have advocated oversubscribed with the capability to adapt requirements on-demand. In this paper, we present design, implementation, evaluation OSA, novel Optical Switching Architecture for DCNs. Leveraging runtime reconfigurable optical devices, OSA dynamically changes...

Inspired by recent advances in compressive sensing (CS), we introduce CS to the radar sensor network (RSN) using pulse compression technique. Our idea is employ a set of stepped-frequency (SF) waveforms as codes for transmit sensors, and use same SF sparse matrix compress signal receiving sensor. We obtain that samples along time domain could be largely compressed so they recovered small number measurements. A diversity gain also obtained at output matched filters. In addition, develop...
In the radar sensor network (RSN), interferences among different sensors can be effectively reduced when waveforms are properly designed. this paper, we perform some theoretical studies on coexistence of phase coded in RSN.

Applying codes and equal-gain combination technique to RSN, study detection performance versus numbers under conditions. The simulation results...
