This paper studies the capacity of hybrid wireless networks with Opportunistic Routing (OR). The authors first extend the opportunistic routing algorithm to exploit high-speed data transmissions in infrastructure network through base stations. They, then develop linear programming models to calculate the end-to-end throughput bounds from multiple source nodes to single as well as multiple destination nodes. The developed models are applied to study several hybrid wireless network examples. Through case studies, they investigate several factors that have significant impacts on the hybrid wireless network capacity under opportunistic routing, such as node transmission range, density and distribution pattern of Base Stations (BTs), and number of wireless channels on wireless nodes and base stations.
