Over the past few years, a large number of IoT solutions have come to the IoT marketplace [2]. Typically, each solution, consisting of one or more Internet Connected Objects (ICO), is designed to perform a single or minimal number of tasks (primary usage). For example, a smart sprinkler may only be activated if the soil moisture falls below a certain level in a garden. Further, smart plugs allo...

Wireless LANs based on the IEEE 802.11 technology are becoming increasingly prevalent. The availability of highbandwidth together with the convenience of being a wireless medium makes it a compelling technology for multimediabased applications. In this paper, we present a gatewaybased architecture of the wireless home media network and develop a secure registration protocol that is appropriate ...

We have developed and deployed several web-based tutors for C++ programming concepts. We have been remotely collecting usage data from these tutors, and analyzing them for the benefit of the students, the teachers and ourselves. In this paper, we will describe the tutors, the types of data collected, and the types of analysis we perform on the data for the benefit of the various constituencies ...

This article describes the context, design, and recent development of the LAPACK for clusters (LFC) project. It has been developed in the framework of Self-Adapting Numerical Software (SANS) since we believe such an approach can deliver the convenience and ease of use of existing sequential environments bundled with the power and versatility of highly tuned parallel codes that execute on cluste...

Many people demand more convenience and smarter service. Due to demand, smart devices have begun to take center stage in terms of portability and functionality in wireless environments, especially mobile communications. To provide secure service, authentication between networks and users’ devices is necessary with proper efficiency. In this paper, we propose an advanced authentication protocol ...

Ecommerce models offer many benefits for business operations, such as convenience and easiness, decreased cost of inventory management, expanded customer base, enabled globalization and business analytics, etc. Virtual business models also promote sustainability by reducing energy and resource usage. Despite its pronounced benefits, ecommerce is still subject to challenges of environmental sust...

Wireless LANs have revolutionized the way in whic h people communicate and share information. The market for wireless applications and hardware is growing at a phenomenal rate. With wireless networks proliferating rapidly, security of these networks becomes a major concern. Networks using the IEEE 802.11b standard have been proven inherently insecure. Hence, there exists the need for a fool -pr...

We present a qualitative, exploratory study to examine the space of electronic communication (e.g. instant messaging, short message service, email) by Deaf teenagers in the greater Atlanta metro area. We discuss differences and similarities between deaf and hearing teen’s usage of electronic communication mediums. Five common themes: Identity, Connection, Control, Tension, and Convenience were ...

The demand bus is a new transportation means, which is timely planned and runs order by order in accordance with independent requests of individual customers. Demand buses are alternative transportation vehicles, replacing traditional routing-oriented buses. In this paper, the authors address the characteristic issues, attend to the practical operations, and estimate and evaluate the trade-off ...
