A mobile ad hoc network (MANET) attracts wide attention as a future device network.For achieving high mobility, ad hoc on-demand distance vector (AODV) routing is suitable.However, an AODV-based MANET is vulnerable against a black hole attack.Secure AODV (SAODV) is the conventional countermeasure in order to bypass a black hole.However, it may cause misrouting under the normal conditions.In order to solve this problem, we propose a novel countermeasure scheme.This scheme comprises AODV, reachability checking function and reachability-information caching function.Reachability checking suppresses misrouting effectively.Furthermore, reachability-information caching suppresses control overhead of reachability checking.As the result, our proposed scheme is an attractive countermeasure against black hole attacks.
