Abstract

We study wireless ad hoc networks that consist of n source nodes and m destination nodes, placed randomly in a two dimensional area. Each source node is creating data traffic that must be delivered to one of the m destination nodes, chosen at random. When m is on the order of n d with 0 < d < 1/2, the capacity of the network is affected by the formation of bottlenecks around the destinations, and the maximum aggregate throughput is on the order of n d. If, however, 1/2 < d < 1, an aggregate throughput on the order of n 1/2 is achievable. The scheme that achieves this aggregate throughput does not suffer from the formation of bottlenecks. These results hold under a general model of channel fading, and with probability going to 1 as n → ∞.
