Mobile Ad-hoc NETworks (MANETs) are especially vulnerable to attacks for lacking infrastructure and data transfer using wireless communication, especial for Denial of Service (DoS) attacks. Black hole and gray hole attack are two kinds of Denial of Service (DoS) attacks and can bring great damage to mobile ad hoc network. This paper demonstrates an adaptive approach to detecting black and gray hole attacks in MANET based on a cross layer design. In network layer, the authors proposed a path-based method to overhear the next hop's action.
