Cloud computing uses internet data centers to host applications and data storage. Cloud computing resources and services are offered to customers on pay-per-use model while the quality of the offered resources and services are defined using service level agreements also known as SLAs. Unfortunately, there is no standard mechanism to verify and assure that services delivered by the cloud provider satisfy...
Traffic accidents negatively affect the lives of human beings. Accidents may result in deaths, severe injuries, and loss of income to the impacted families. Accident detection and prevention is a keystone in improving road safety. In this paper, a system for detecting vehicle collision and rollover is presented. The proposed system includes three key phases. Data acquisition where accelerometer and...
Virtual Desktop Infrastructure (VDI) is a new generation of cloud service in which users operating systems execute in a cloud data center. Users can access their desktops and applications by using thin client devices. This thin client is consisting of only a screen attached with low power CPU. This new paradigm of delivering remote desktop provides benefits in terms of flexibility, cost reduction,...
Nowadays, most of communication systems are well suited for the evolving technology of Software-Defined Radios (SDR). Despite the wide variety of SDR applications, one trait is common among them which is the frequency hopping. Systems utilizing frequency hopping with high hopping rates have strong limitations on the frequency tuning time. In this paper, we assess the influences of several tuning options,...
This paper presents a systematic methodology for exploring possible processor arrays of scalable radix 4 modular Montgomery multiplication algorithm. In this methodology, the algorithm is first expressed as a regular iterative expression, then the algorithm data dependence graph and a suitable affine scheduling function are obtained. Four possible processor arrays are obtained and analyzed in terms...
This paper presents a new processor array architecture for scalable radix2 Montgomery modular multiplication algorithm. In this architecture, the multiplicand and the modulus words are allocated to each processing element rather than pipelined between the processing elements as in the previous architecture extracted by C. Koc, and also the multiplier bits are fed serially to the first processing element...
