Executive Summary

The authors attempt to quantify end-to-end throughput in multi-hop wireless networks using a metric that measures the maximum density of source-destination pairs that can successfully communicate over a specified distance at certain data rate. They term this metric the random access transport capacity, since it is similar to transport capacity but the interference model presumes uncoordinated transmissions. A simple upper bound on this quantity is derived in closed-form in terms of key network parameters when the number of retransmissions is not restricted and the hops are assumed to be equally spaced on a line between the source and destination.
