Popular smart wireless devices become equipped with multiple radio interfaces. Multi-homing support can be enabled to allow for multiple simultaneous associations with heterogeneous networks. In this paper, the authors focus on video streaming traffic and propose analytical approaches to evaluate the packet-level and call-level performance of a multipath transmission scheme, which sends video traffic bursts over multiple available channels in a probabilistic manner. A Probability Generation Function (PGF) and z-transform method is applied to derive the PGF of packet delay and any arbitrary moment in general.
