Resta G., Santi P. On the Fundamental Limits of Broadcasting in Wireless Mobile Networks. In: INFOCOM 2010 - 29th IEEE Conference on Information communications (San Diego, CA, 15-19 March 2010). Proceedings, pp. 126 - 130. IEEE Press, 2010.
In this paper, we investigate the fundamental properties of broadcasting in mobile wireless networks. In particular, we characterize broadcast capacity and latency of a mobile network, subject to the condition that the stationary node spatial distribution generated by the mobility model is uniform. We first study the intrinsic properties of broadcasting, and present a broadcasting scheme that simultaneously achieves asymptotically optimal broadcast capacity and latency, subject to a weak upper bound on the maximum node velocity. We then investigate the broadcasting problem when the burden related to selecting relay nodes is taken into account, and present a combined distributed leader election and broadcasting scheme achieving a broadcast capacity and latency which is within a poly-logarithmic factor from optimal
