In this paper, we present a solution to efficient multimedia streaming applications over P2P networks based on the foresighted resource reciprocation strategy. We study several priority functions that can explicitly consider the timing constraints and the importance of each data segment in terms of multimedia quality, and successfully incorporate them into the foresighted resource reciprocation strategy...
Wireless actuators are small scale devices that can receive/accept instructions and act on their environment. The IP Multimedia Subsystem (IMS) is a key component for 3G networks. It aims at seamless provisioning of multimedia services. Combining actuation capabilities with IMS capabilities will certainly enable novel value added services. This paper proposes an architecture for the integration of...
With recent advances in video encoding and network technology, media streaming services are getting popular. Media streaming system based on the traditional server/client or CDN architecture has a scalability problem, and peer-to-peer media streaming system using resources of peers in the system can provide better scalability. Previous media streaming services are suited to play stored contents such...
This paper designs and implements an automatic network system utilizing UPnP, wireless network and power line carrier technology. We connect home media device and home gateway device via wireless network to build media service subsystem, and connect home applications and home gateway via power line carrier network to make power control subsystem. Then we convert both subsystems into UPnP virtual devices,...
GPRS or the general packet radio service is a non-voice value added technology that allows data communication over mobile phones in an Internet Protocol (IP)-based network [11]. This paper focuses on the transmission of voice over the existing data channel in GSM/GPRS networks using a Web server. Since the data channel in any network is economically viable for transmission, a mechanism to transfer...
Deployment of VoIP service brings in security challenges that necessitate additional protection measures for corporate networks. Logging of VoIP sessions between a corporate LAN and the Internet becomes an essential requirement, to prevent misuse, to enforce security policies and to respond to security incidents. Identifying valid VoIP sessions and call tracking from the signaling to media session...
