In this paper, the authors consider a large-scale wireless ad hoc network with multiple source-destination communication pairs, where the sources operate with wireless energy harvesting. Before data transmission, each source should first harvest the radio frequency energy transferred from its corresponding destination. Since the source-destination distance is long, the efficiency of wireless energy transfer is ...

The idea of pay-per-use computing incarnated by the cloud paradigm is gaining a lot of success, both for entertainment and business applications. As a consequence, the demand for computing, storage and communication resources to be deployed in data center infrastructures is increasing dramatically. This trend is fostering new forms of infrastructure sharing such as cloud ...

To meet the growing mobile traffic demand, deployment of Heterogeneous Networks (HetNets) is proposed as a solution to enhance network capacity. It will enable the coexistence of several systems consisting of macro, micro and femto or Wi-Fi layers. However, the main issue is the coexistence due to mutual interference. To guarantee that HetNet performance will ...

Cooperative communication with spectrum sharing has been proved to be an efficient way to reduce energy consumption. In this paper, an optimal power allocation algorithm is proposed for mobile cooperative beamforming networks, where several Secondary Users (SUs) collaboratively act as relay nodes to assist the transmission of a Primary User (PU) in reward of transmitting ...

Multiuser cooperative communication significantly improves the performance of wireless communication networks. One key challenge of multiuser cooperative communication is how to design a cooperative mechanism to incentivize potential relay nodes to help a source node in its data transmission. In this paper, to address this problem, a contract-based principal-agent framework is proposed in the context ...

Tripleset interlinking is one of the main principles of linked data. However, the discovery of existing triplesets relevant to be linked with a new tripleset is a non-trivial task in the publishing process. Without prior knowledge about the entire Web of data, a data publisher must perform an exploratory search, which demands substantial effort and ...

Markov Chain Monte Carlo (MCMC) is a family of algorithms which is used to draw samples from arbitrary probability distributions in order to estimate – otherwise intractable – integrals. When the distribution is complex, simple MCMC becomes inefficient and advanced variations are employed. This paper proposes a novel FPGA architecture to accelerate parallel tempering, a ...

In this paper, the authors present a new transistor sizing methodology called Free Power Recovery (FPR) for low power circuit design. The objective of this methodology is to minimize the total power of a circuit by accounting for node switching activities and Leakage Duty Cycles (LDCs). The methodology has been incorporated into the EinsTuner circuit ...

Introduced in cryptography for code-breaking purpose, the Weil and Tate pairings are at the heart of an ever increasing number of protocols since the work of the researcher who first discovered their constructive properties. The interested reader should refer to the survey by the researchers for further details. According to, when dealing with general curves ...

Multimedia database management systems manage multimedia data including text, images, audio and video. More and more multimedia data are now available on the web and effective management of this data is becoming a critical need. This paper describes security and privacy issues for multimedia database management systems. Multimedia data includes text, images, audio and video. ...
