Named Data Networking (NDN), aka Content Centric Networking (CCN), excels in content distribution especially multimedia distribution, which can consume significant network bandwidth. With the market penetration of mobile devices and advancement of wireless technologies, media streaming over Wi-Fi becomes increasingly popular but it does not scale well in today's IP based networking. A natural question...
Wi-Fi phones are becoming extremely popular for implementation of VoIP (or VoWLAN) service. It is well known that voice service is quite critical to delay and delay jitter, therefore it appears important to evaluate VoWLAN service performance. In the research presented below we implemented a typical indoor environment for VoWLAN service using OPNET. Simulation parameters have been carefully selected...
Technological advances allow handheld devices to be equipped with faster processors and wireless interfaces, making the performance comparable to laptop Computers. In this paper, we describe real-time video streaming over heterogeneous networks namely Bluetooth, Wi-Fi and GPRS-EDGE. The wireless channel used for communication in different network varies in their Bandwidth, supported Bit rate and Unequal...
