This paper addresses whether Mobile Cloud Computing models can be used to extend the capabilities of resource constrained mobile devices to provide the illusion of infinite, elastic resources on demand. We identify five key limited resources as being CPU, memory, battery, data usage and time. Existing solutions for these limitations are explored, and we identify offloading computation and storage...
Dramatic increase in smartphone sales and third-party applications that users can download has significantly increased the possibility of rootkits and malware targeted for smartphones. This paper discusses the current state of research in detection and mitigation of propagation of malicious code, such as viruses, malware and even rootkits in smartphones. A new strategy is introduced that offers a...
REsource LOcation And Discovery (RELOAD) is a peer-to-peer signaling protocol that can be used to maintain an overlay network, and to store data in and retrieve data from the overlay. RELOAD is currently being standardized in the Internet Engineering Task Force (IETF). The main application using RELOAD is Peer-to-Peer Session Initiation Protocol (P2PSIP). In this paper, we study the performance of...
In this publication several near field communication (NFC) based sensor demonstrations and related measurements are discussed. These include basic temperature sensor applications and some more complex scenarios with external sensors and actuators. The reader device can be a commercial NFC enabled mobile phone or specially developed hardware. Based on the experience gathered with demonstrations and...
In this paper, we describe HW and SW features of the developed prototype of a hybrid of 3G mobile phone and wireless terminal, which provides integral video projection onto two VGA/2 displays. These could be fold/collapsed one onto each other, or re-mounted, while the ratio of the total length-to-height is 4:3, so preserving integral video VGA format and, consequently, displaying Internet content,...
Today's mobile devices have inherited many of the characteristics of desktop computing -- including the assumptions that the user's full attention and dexterity can be focused on the interface. Unfortunately, on-the-go users are impaired by their mobility and often find desktop-style Windows Icon Menu and Pointer (WIMP) interfaces difficult, if not impossible, to use while performing their primary...
Class D amplifiers are becoming the most feasible solution for embedded audio application. However, distortions due to the non-linear nature of switching stage are the main drawback for this amplifier topology. This paper discusses the design and implementation of high fidelity audio class D using sliding mode control scheme. This design method proves to be a cost effective solution for industrial...
