With the growth in computing needs, energy cost includes a large portion of operating cost of cloud data centers. Electricity prices vary in different times and geographical places. Such diversity provides opportunity for diminishing total cost via migration of jobs to places with lower energy prices. Most of the previous studies only focus on computing… (More)
A 26-32GHz quadrature cascaded phase locked loop (PLL) is presented. The PLL is implemented in 65nm bulk CMOS, consuming 27mW and has less than 100fsec integrated jitter with -114.4 and -112.6dBc/Hz phase noise at 1MHz offset for integer and fractional modes, respectively.
This paper introduces the concept of rate privacy in the context of wireless sensor networks. Our discussion reveals that the concept indeed is of a great importance for the privacy preservation of such networks. As a result, we propose a buffering scheme to protect the rate from adversaries. Simulation results verify the applicability of our approach.
