Social learning is a natural way of acquiring knowledge and approaching various problems. In high education, students widely use social learning which is to a large extent facilitated by todays' popular social network applications. However, as of yet high education systems typically do not recognise the value of the data produced by or embedded within these social network applications. In this paper...
The paper deals with the comparison between the frequency domain and time domain analysis of transient electric field generated by the ground penetrating radar (GPR) dipole antenna and transmitted into the dielectric half-space for GPR antenna. The time domain integral equation (TDIE) approach is based on the Hallen integral equation for half-space problems. The numerical solution is carried out via...
In this paper we provide efficient statistical tools for the prediction of the required number of satellite terrestrial stations in a hybrid Satellite — Mobile Ad Hoc NETwork (MANET). We propose to consider the average statistical behavior of the network. We first analytically estimate the number of hybrid satellite gateway stations (HSs) in a typical cluster. A strategy for the terrestrial path discovery...
In this paper, we present a new coding scheme for adaptive transmission of image data in the context of cloud gaming. The merit of our approach is to adapt efficiently to the diversity of the devices that can be used to access to the gaming platform. Particularly, we show that our scheme fits with the stringent requirements imposed by the lack of CPU, memory, and storage resources in the mobile devices...
With the development of Internet, new applications are emerging in an endless stream, and traditional applications are constantly changing. Over the past decade, Internet applications develop rapidly, and great changes have taken place in application traffic characteristics of ordinary hosts and servers. Analyzing Internet application traffic characteristics is meaningful to understanding today's...
Cognitive radio is the fundamental component for the future generations of wireless communication. Indeed, by sensing its environment, the cognitive radio will be able to exploit unused frequencies for opportunistic wireless communications. In this paper, a new sensing method in the narrowband context is proposed for ray propagation channels by combining the spatial scanning technique with the maximum...
Future wireless networks are witnessing a major demand for mobile data, which necessitates reconsidering the design and deployment of their infrastructures. To fill this gap, the next-generation mobile 5G is defined as one of the promising solutions. Although the heterogeneous network, the small cell concept and the Cognitive Radio (CR) are considered as key drive technologies for 5G, the major challenge...
