In this paper, the authors present pocket caching, a prefetching cache strategy to identify the data to be loaded in a mobile node participating in a Mobile Cloud Computing (MCC) environment. MCC is a new paradigm and is consider as the extension of mobile devices services in an elastic and transparent way through the ubiquitous ...

Network forensics is a subtopic of digital forensics wherein research on artifact investigations and intrusions evidence acquisition is addressed. Among many challenges in the field, the problem of losing data artifacts in the state of flux, (i.e., live volatile data), when network devices are suddenly non-operational remains a topic of interest to many investigators. This ...

Web mining is an exciting discipline in the domain of data mining as well as in classification/clustering. Identifying the usage patterns of users is very important in utilizing the vast information available in the World Wide Web. Web usage mining entails identifying usage pattern and has many practical applications. It focuses on techniques that have ...

Service Level Agreement (SLA) is one of the common means of communication between customers and service providers through which one of the most important parameters for the customers, connection availability is requested. This paper presents a dynamic service level agreement negotiation mechanism considering intra/inter-domain communications over shared mesh optical networks. The intra-domain negotiation mechanism propagates ...

VoIP and internet users are more and more interested in the multimedia communication services and this has made the academic research in this domain to be risen dramatically. Media servers play a key role in multiple communications and voice and video conferencing. Thus, implementation and evaluation of media servers has a great importance in the ...

In this paper, the authors propose a MOS-BJT-NDR circuit, which can show the Negative-Differential-Resistance (NDR) characteristic in its current-voltage curve. This NDR circuit is composed of standard Si-based Metal-Oxide-Semiconductor Field-Effect Transistor (MOSFET) and Bipolar Junction Transistor (BJT). Therefore, they can implement the applications using the standard CMOS process. They demonstrate the design of some logic ...

In this paper, a two stage (stego-based-crypto) invertible technique is proposed based on cryptography and steganography algorithms. In order to increase the security, the proposed paper uses RSA cryptographic algorithm in the first stage for encrypting the secret message, and Integer Wavelet Transform (IWT) based lifting scheme in the second stage as a steganography algorithm ...

Data warehousing technology aims at providing support for decision making for operational data. Defining a data warehouse for data stored in XML (eXtensible Markup Language) format should be addressed as various organizations use XML to facilitate the promotion of their businesses. In this paper, the authors describe a semi-automated approach for designing multiple cubes of ...
