Real-world evaluation of ring flooding

Flooding is a basic mechanism frequently used in mobile ad-hoc networks. In its simplest form flooding is realized by letting each node rebroadcast the flooded packet exactly once. To limit the scope of a flooded data packet, the sender of the packet may use ring flooding . For this, the packet's time-to-live (TTL) field is initially set to n . As the TTL of the packet expires after n hops, it only reaches all those nodes that are at most n hops away from the original sender. Ring flooding is used, e.g., to distribute information only relevant in a certain area such as emergency messages in car-to-car networks, or to do an expanding ring search during route discovery as in AODV [2].
