Cloud computing has attracted a lot of interest from both industry and academia. Many business models have been proposed to bring together cloud consumers and providers. In this paper, a resource trading framework is proposed as an alternative business model for clouds. The under-utilized cloud resources are being solved to potential customers by the guidance ...

Wireless Sensor Networks (WSNs) are networks of small and tiny lightweight nodes that are randomly deployed in a large area where it is not possible to monitor continuously. Some physical parameters such as pressure, temperature and relative humidity etc. are used for monitoring the same. Energy consumption is the most important and critical issues for ...

Task of locating particular seats in a partially (or otherwise) occupied auditorium can be difficult. The need for this may arise in a variety of situations in the emerging IoT centric world. They present in this paper the development of a system they have tagged Seat Sense. It is a means of detecting the availability ...

In this paper, a composite Rayleigh-gamma distribution is proposed for the urban wireless channel environment which represents small-scale fading with no Line-of-Sight (LoS) and shadowing. Moment Generation Function (MGF) and truncated MGF for the proposed model are derived. Using these MGFs, the performance of digital communication systems is investigated in terms of channel capacity and ...

The growth and application of mobile devices in accessing multimedia contents, including mobile video calls and distribution of images among people globally is constraining the wireless network resources. Due to dynamic nature of wireless network and limited networking resources, adaptation scheme for improved multimedia communication is proposed. Considering the impact of channel errors on received ...

In this paper, the authors contain an analysis of the application of 3D scanning in the process of creating a very precise numerical model of historical buildings. 3D scanning is used in inventory documentation with the visualization of a building and the creation of 3D models in most cases. As a result of 3D scanning ...

The solution of composite partial differential equations is an indispensable step in numerous scientific applications. However, this is a computationally and memory demanding process for large-scale differential equations. This is especially true for multi domain/multi physics problems, which require application of an Interface Relaxation (IR) methodology on the common boundaries between domains. In this paper, ...

With the growing need for user-friendly design of mobile software, user experience has attracted more attention from researchers and practitioners. In particular, it is vital to improve the user acceptance of mobile recommendation systems that are new technologies that provide convenience for mobile device users. Based on recent studies, this paper provides a conceptual framework ...

In this paper, the authors review a comparison study on the most common used authentication methods. Some of these methods are actually based on cryptography. In this paper, they show the main cryptographic services. As well as, this paper presents a specific discussion about authentication service. Since the authentication service is classified into several categorizes ...

The increasing demand for renewable energy from sources such as wind and solar has attracted the researchers to study the behavior and attributes of these energy resources in more depth. One of the important aspects of renewable energy resources is their uncertainty/unpredictability. To have a balance between the power demand and generation, it is important ...
