Recent research in mobile ad-hoc networks (MANETs) mostly deals to minimize the broadcast expenses of route discovery by controlling the query-broadcast. In this regard, a variety of broadcast-repealing schemes have been proposed, and employed to improve effectiveness and efficiency in various aspects of route-discovery considering time and energy. These schemes mainly focus on reducing unnecessary propagation of route-query by repealing the query-broadcast. Time-to-live based broadcast is the most common controlled-flooding scheme widely used in routing protocols. Recently some other broadcast-repealing schemes are proposed which work based on chasing-policy. The critical and analytical assessment to evaluate these schemes such aspects is of great importance. In this paper, we investigate their query-diffusion process, and their merits and demerits.
