Throughput Capacity of Interference-Limited Hybrid Wireless Networks

In this paper, the capacity of ad hoc wireless networks with infrastructure support based on physical model is studied. In the hybrid wireless network model, base stations are placed in a regular pattern, but nodes are independently and uniformly located within a unit area. Two scaling regimes are identified, depending on the growth of the number of base stations relative to the number of nodes. We show that under our routing strategy, a minimum growth speed of the number of base stations is needed, before the base stations start to have an effect. Above the growth speed, the maximum aggregate throughput capacity grows linearly with respect to the number of base stations.
