A Mobile Ad-hoc NETwork (MANET) is a self-organizing, infrastructure less, multi-hop network and mobile nodes are free to move in any network. Due to their lack of centralized control, and dynamic topology, MANETs are vulnerable to many attacks. From a security design perspective, there is no built-in security. So, security is one of the main concerns in ad hoc networks. In this paper, a technique DDBA-DSR is presented to protect against the deep black hole attack.
