Abstruct -We show how flooding can be adopted as a reliable and efficient routing scheme in ad-hoc wireless moblle networks. It turns out that, with the assistance of some tunable heuristics, flooding is not necessarily inferior to sophisticated point-to-point forwarding schemes, at least for some classes of wireless applcs tions. We discuss a reactive broadcast-based ad-hoc routing prcr tocol in which flooding exhibits a tendency to converge to a narrow strip of nodes along the shortest path between source and destination. The width of this strip can be adjusted automatically or by the user, e.g., in response to varying node density and m e bility patterns, Finally, we point out a certain deficiency inherent in the IEEE 802.11 family of collision avoidance schemes and show how to fii it to provide better service to broadcast-based routing schemes represented by our variant of controlled floo& ing.
