Rating: (0)

Overview: Many ad hoc network protocols use flooding as the basic mechanism to propagate control messages. The blind flooding can become very inefficient because of redundant, ""Superfluous"" forwarding. In fact, superfluous flooding increases link overhead and wireless medium congestion. In a large network, with heavy load, this extra overhead can have severe impact on performance and should be eliminated. Efficient flooding schemes to choose a dominant set of nodes have been recently proposed in ad hoc networks. This paper compares the performance of a set of representative schemes via simulation using as criteria the flooding efficiency and the delivery ratio.
