Modern technology allows for surveying through different media (e.g. Internet, mobile phones, tablets), which may influence the quality of collected data with additional effects due to the survey mode and should be pretested with the purpose of avoiding effects that would deteriorate the quality of collected data. In the present study, we analysed the technological development of surveying tools by...
After analyzing SRTP (Secure Real-time Transport Protocol) and SIP(session initiation protocole), we identified the need to secure VoIP(Voice over IP) network. Ourstudy assesses the risk of attacks on the VoIP network. Additionally, it offers solutions to the existing VoIP network vulnerabilities while issuing Instant Messages. Using cryptography, we present a general proposal for secure VoIP instant...
Variable economic conditions, new forms of customer buying behavior and in particular new technology is likely to cause the emergence of new or growing existing hospitality markets. In developed European economies, all the more attention is paid to studying the role of new technologies in the field of hospitality marketing. Research focus will be directed towards the usage of technological systems...
This paper discusses the viability of using Session Initiation Protocol (SIP) transport for Smart Grid signaling. Smart grids will jointly optimize energy production and demand, in a scenario with millions of smart meters and microenergy sources (e.g. solar panels or electric cars). This will place stringent requirements on telco networks. Information technologies will have to provide scalable signaling...
Voice over Internet Protocol (VoIP) is one of the emerging technologies today. This application offers the user a service by which one can call another person at a low cost as compare with traditional phone services. One drawback to the Internet is spam, which are unsolicited or unwanted objects which often appear as unwanted messages in various email applications. For VoIP, spam refers to unsolicited...
The following topics are dealt with: web services composition; HTTP communication; latent semantic indexing; virtual communities; XML Web services interactions; casual multiuser Web collaboration; Web blog mining application; social network services; instant messaging; location-based personalized social media service; real-time quality of service; semantic Web services; e-learning services; secure...
This paper discusses the possibility of adopting the concept of knowledge based systems [KBS], in general, and conceptual maps, in particular, in email classification system. Needless to say that email has the potential to improve efficiency and reduce costs involved in communication. Even after the advent of newer technologies such as instant messaging and VoIP, email remains the top most application...
Voice over IP (VoIP), which provides real-time speech communication between two users in a way that closely resembles a face-to-face conversation, has had a significant impact on the multibillion-dollar telecommunication industry. The promise of less expensive phone calls with comparable quality and better features than public switched telephone networks (PSTNs) has accelerated VoIP's adoption, both...
The IP Multimedia Subsystem (IMS) is a promising technology, designed to provide IP based telephony and real-time multimedia services. The 3 GPP specifications define a complex IMS architecture for the convergence of voice, video and data. It enables provisioning variety of multimedia services, such VoIP, video streaming, conferencing, instant messaging, web browsing, e-mail, push-to-talk, online...
Various forms of ad-hoc networking are slowly emerging. However, a wider diffusion of ad-hoc networking in everyday life will only be possible if existing common applications are adapted for use in ad-hoc networks. There has been some work on adapting Internet-based applications to function in ad-hoc networks. Yet, in order to make ad-hoc networking even more useful and interesting to people, applications...
SIP has been used to develop many kinds of SIP service, such as instant messaging, conference and presence, and these various services are being bundled to one application. To make an application which supports various services may be not easy since the behavior of transaction user of the application is obviously become very complicated. In this paper, we describe a design of SIP transaction distributor...
