Abstract

Flooding is often used as a building block for route discovery in routing protocols for mobile ad hoc networks. The traditional implementations of flooding suffer from the broadcast storm problem. To solve the broadcast storm problem, some efficient flooding schemes have been proposed. However, there also exist many problems in these schemes, such as signal collision. In this paper, we propose a comprehensive efficient flooding algorithm called CEF to extend our previous work in [1]. We attempt to solve the problems which are not solved by our previous proposed algorithm. We have implemented our algorithm in ns-2 simulator, and the results show that our algorithm achieves better performance than Pure Flooding, EF1 (the algorithm proposed in [2]) and our previous proposed algorithm due to smaller number of signal collisions.
