Abstract

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 Error Protection coding techniques. In Bluetooth we can create a Bluetooth PAN (Piconet) in which mobile computers can dynamically connect to master and communicate with other slave. In Wi-Fi real-time video streaming over wireless LANs for both unicast and multicast transmission. The wireless channel is modeled as a packet-erasure channel at the IP level. The video delivery system in GPRS-EDGE is based on MPEG-4 video simple profile and on the IETF protocols RTSP, RTP, and RTCP for the media delivery and synchronization in compliance with the 3GPP specifications for Packet Streaming services (PSS).
