Executive Summary

The integration of different wireless access technologies combined with the huge characteristic diversity of supported services in next-generation systems creates a real heterogeneous system. This heterogeneity opens new avenues for improving the system utility of both operators and users. In this paper, the authors propose a Pseudo-optimal Greedy Media Streaming (PGMS) algorithm to reduce the cost of streaming sessions using an optimization framework that considers the real-time requirements of the vertical hand-off decision. The proposed algorithm results in noticeable reductions in session cost, signaling load, and blocking probability in comparison to previously proposed heuristics.
