Compared to the previous paper, which takes the route of simulation, this paper is much more convincing since it carries a physical deployment in a real environment. There are so many factors not modeled(or difficult to model correctly) that can have significant impact on network performance in complex urban neighborhood. (Obstruction, interference , etc.)
The main contribution of the paper is the evaluation of the multi hop routing performance and their routing protocol Srcr which tries to find highest useful throughput rate between any pairs of nodes. It seems plausible in urban environment because of the high density of quality links, this sort of sharing between different home users can boost speed even higher (due to time multiplexing) and possibly guard against outage of a single provider.
