Unstructured peer-to-peer systems represent viable candidates for supporting distributed applications with frequent node failures. This paper presents a framework to study the reliability of evolving overlay networks in presence of faulty nodes. We focus on the node degree distribution, an important metric to understand whether the topology of the overlay can be maintained in presence of peer churns...
Network virtualization can diversify the future Internet architecture into separate virtual networks according to different applications and requirements. Telecom operators adopt network virtualization technologies to design virtual networks to meet users' requirements and achieve high efficiency, low cost, controllability, etc. Previous researches focus on virtual networks construction based on restriction...
This paper describes a comparative analysis between two topologies of operational amplifiers to design a 40 MS/s 12-bit pipeline analog to digital converter (ADC). The analysis includes AC and transient simulation to select the proper topology. This ADC is implemented in a 0.35 mum AMS CMOS technology with 3.3 V single power supply. The capacitors and selected operational amplifiers were scaled for...
