Description: In this paper, we propose an effective end-to-end
virtual path construction system, which exploits path diversity
over heterogeneous wireless networks. The goal of the proposed
system is to provide a high quality live video streaming service
over heterogeneous wireless networks. First, we propose a
packetization-aware fountain code to integrate multiple physical
paths efficiently and increase the fountain decoding probability
over wireless packet switching networks. Second, we present a
simple but effective physical path selection algorithm to maximize
the effective video encoding rate while satisfying delay and
fountain decoding failure rate constraints. The proposed system
is fully implemented in software and examined over real WLAN
and HSDPA networks.
