Mobile sensors networks are used in several domains to perform various tasks related to monitoring, recording, and affecting the conditions of an environment. Interacting with mobile sensor networks deployed in public networks requires an application capable of securely exchanging data in the network, generating mobile sensor network requests and processing mobile sensor network responses. Embedded...
With the advancement of Internet technologies and the widespread use of mobile devices, the number of users in conferencing services is increasing quickly. A P2PSIP conferencing system and an IP Multimedia Subsystem (IMS) conferencing system have been designed to provide conferencing services. The IMS conferencing system was developed to adapt to a server-based centralized system, while the P2P network,...
This paper presents an architecture which allows consumers to securely share the services available in their home networks with remote third parties. It is implemented as a software service which can be installed on a home-gateway device. The implementation supports dynamic sharing of UPnP-compliant devices and multimedia content and enables complex service compositions across federated homes through...
Telecom based service providers are relentlessly trying to accelerate their service offerings to match the pace at which the users are embracing the Web. In reality IMS based Telecom and Internet based Web 2.0 networks have their own advantages and need to co-exist to create an enriched user experience. The convergence of IP Multimedia subsystem (IMS) based Telecom and Web 2.0 based networks is slowly...
Based on the investigation on current convergent methods for IMS services and Web 2.0 services, a Component Based Convergent Services Architecture (CBCSA) is proposed. The architecture and the work mechanism of CBCSA are discussed in detail. By fully making use of COM characteristic, the Telecom services can be composited freely and the Web 2.0 services and Telecom services can cooperate efficiently...
In this paper, we propose a secure system model for interconnection between P2PSIP and IMS domains. The interworking solution is based on P2P-IMS GateWay (PIGW), which acts as a normal peer in P2PSIP network and a 3rd party IMS Application Server (AS) in IMS network. The security is achieved by implementing Chord Secure Proxy (CSP) and enhanced with subjective logic based trust model. We also implement...
Mobile VoIP based on IP Multimedia Subsystem (IMS) is one of the most issues according to introducing UTRAN long term evolution (LTE) networks. In addition to, there are many hot spot such as WLAN of free worldwide directory. In order to provide a mobile VoIP service over various networks, it is important to define VoIP architecture and provide interconnection at the service & media layer between...
Multi-media based applications have increased immensely in the last few years. The need to have better video quality, higher recording and playback time, more video channels and faster time to market (TTM) requires DFT solutions that use core-based testing to allow concurrent IP and SOC development, scalable to support multiple technologies and eases the development of timing constraints. This paper...
The IP Multimedia Subsystem (IMS) is becoming the de-facto standard for IP-based multimedia services, while Wireless Sensor Networks (WSNs) are gaining a lot of popularity due to their ability of capturing a rich set of contextual information and their high application potential. Making the rich set of contextual information, captured by WSNs, available to the IMS can greatly enhance its service provisioning...
In this work we present a model for online charging of media-rich services supporting dynamic QoS negotiation, within the third generation partnership project (3GPP) IP multimedia subsystem (IMS) emulated environment. In the QoS negotiation process a user, a network provider, and a service provider negotiate about the session to be initiated, resulting in an user-specific combination of media components...
Multimedia services delivery in converged IP networks using IMS, concentrates on providing capabilities to ensure the best quality of service. We have designed a set-top box which provides feedback in IMS architecture to ensure end-to-end QoS and moreover, enables the functionalities of regional gateway for a home network.
Interpersonal communication using the information networks can be accomplished in many different ways. Users may communicate, for example, by using a specific communication application on an end-user terminal, typical mobile phone, or IP Multimedia Subsystem (IMS) client. Quite often there is no interconnection mechanisms between these different communication methods, and this is emphasized with regards...
The sensor networks had been used for various application areas and showed effectiveness under the prior application planning and right circumstances that includes cost, data handling and other resources. In order to generalize, it is required to reduce initial cost and use data effectively. This paper proposes connecting a sensor network with the IMS that is the service platform of the NGN to solve...
The IP multimedia subsystem (IMS) could very well be the best solution for most telecom operators. The more recent releases have included interfaces to fixed line networks and wireless LANs. This has consequences both for the migration of the core network as well as the integration of future mobile services and applications. Also, an interworking between IMS providers is considered to be a major step...
In this paper, the author describes the design and implementation of a LDNA (Digtal Living Network Alliance) Framework for Handheld devices. DLNA has developed guidelines for interoperability among home devices enabling a multitude of usage scenarios for sharing digital content such as A V (Audio Visual), Photo, and Audio. The proposed DLNA (Digital Living Network Alliance) Client Framework handles...
Video-streaming can now be offered on third-generation (3G) mobile networks. Most research efforts have focused on video download. This paper presents a detailed study of challenges faced for successfully deploying applications requiring life video upload. Both subjective and objective qualities as well as the effects of mobility are analyzed on real 3G networks. Consequently, video profiles are identified...
