By using robots as routers, a team of networked robots can provide a communication substrate to establish a wireless mesh network. The mobile mesh network can autonomously optimize its configuration, increasing performance. One of the main sources of radio signal fading
in such a network is multi-path propagation, which can be mitigated by moving the senders or
the receivers on the distance of the order of a wavelength. In this paper, we measure the performance gain when robots are allowed to make such small movements and find that it may be as
much as 270%. Our main contribution is the design of a system that allows robots to cooperate
and improve the real-world network throughput via a practical solution. We model the problem
of which robots to move as a distributed constraint optimization problem (DCOP). Our study
includes four local metrics to estimate global throughput.
