In real-time video applications, where unreliable networks are commonplace, corrupted video packets can adversely affect visual quality. In this paper, we present a novel maximum likelihood approach to performing video error correction. Rather than ...

The European standards for the aerospace industry (ECSS series) include system adaptation and installations requirements as one of sixteen types of non functional requirements (NFR) for embedded and real-time software. A number of concepts are provided ...

Many technologies have recently made noticeable changes in several domains. This paper will shed the light on the field of transportation to improve the life quality of visually impaired persons (VIPs) using some of these technologies such as Radio ...

This paper describes one practical approach for creating context-aware browser for mobile subscribers. Our model uses mobile phone as proximity sensor. In our concept, any existing or even especially created Wi-Fi hot spot or Bluetooth node could be ...

In the last few years, Aspect Oriented Software Development (AOSD) and Context Oriented Software Development (COSD) have become interesting alternatives for the design and construction of self-adaptive software systems. An analysis of these technologies ...

Augmented Reality (AR) as a vastly growing technology in the mobile computing domain is becoming mature enough to engender a variety of applications for the end user, especially in the educational domain. In this paper, we explore the possibility of ...

Contextual information are used to describe situations of entities (users and devices) and their interactions. Applications need such information in order to adapt their behaviour in response to changes in the entities context. In certain scenarios and ...

We have built a prototype mixed-reality advertising and web publishing service to investigate new forms of advertising and mobile aspects in mirror worlds. The mirror world is the concept of visually mirroring the real world and enabling interaction ...

The efficient browsing and retrieval of videos is a fundamental part of current multimedia systems especially on mobile devices. One way to provide enjoyable video browsing to the users is by providing summaries of the videos whereby the users can have ...

The increased volume of transaction and communication over the World Wide Web in industries like banking, insurance, healthcare, travel and many others has triggered a number of unprecedented security issues. Most web applications today are susceptible ...

This paper outlines an obstacle recognition system for the blind people using the Radio-frequency identification (RFID). In order to walk without being accompanied, people with visual impairment use touching clues such as canes. The main concern of ...

These days smart phones have changed the concept of mobile platform. Due to rapid growth in affordability, increased sensory and computational power has opened the ways for some interesting applications like activity recognition, gaming, navigation/...

recently there have been some efforts, albeit limited, to identify the optimal use of the available arrays of data in higher education for many purposes, such as to identify those students who are at risk and to evaluate student dropout rates. In the ...

A promising feature brought along the progressive deployment of LTE concerns the increase of the uplink bandwidth. We focus in this paper on an innovative usage associated with this new capability and defined by the simultaneous transmission toward ...

The IP Multimedia Subsystem (IMS) is one of the key components of third generation (3G) networks, while Wireless Sensor Networks (WSNs) are an emerging type of networks formed by a set of distributed sensor nodes that collaborate to monitor physical and ...

Emergency networks formed by First Responders are characterised by fairly dynamic topology fluctuations which makes them an area of interest for the incorporation of cooperative transmission and autonomic system design enhancements. It results mostly ...

Various services, such as streaming, network games and thin clients, which keep a session state of user equipments (UEs) for a long period, are provided from servers. This paper proposes a session state migration which relocates session states from one ...

Routing is one of the most significant challenges regarding mobile ad hoc networks (MANETs). Having no fixed infrastructure as well as frequent changes of network topology, as a result of nodes mobility, necessitates cooperation of all nodes in routing ...

Single Radio Voice Call Continuity (SRVCC) is current standardized solution for voice call handover from LTE to circuit core systems. This paper discusses the weakness of SRVCC, and proposes a new solution named Forward Handover for Voice Call ...

By complementing basic call services, supplementary services totalling nowadays more than twenty different functions, have a long history crossing the main areas of telecommunications from ISDN via ETSI GSM, ETSI TISPAN to finally end at 3GPP and GSMA. ...

In this work we investigate the performance of the Always Best Packet Switching (ABPS) operation approach. ABPS is a cross-layer wireless communication scheme that enables mobile terminals to exploit its multiple Network Interface Cards (NICs) ...

A new scheduling module, the Selective Early Detection (SED) mechanism is proposed in this paper. An experimental evaluation in order to demonstrate how this algorithm succeeds in enhancing the quality, improving the performance and easing the ...

Increasing demand for ubiquitous high speed data access has resulted in widespread deployment of heterogeneous wireless networking domains. Integration of heterogeneous networks presents some considerable challenges which include the demand for seamless ...
