Developing a BDSR scheme to avoid black hole attack based on proactive and reactive architecture in MANETs

Abstract

In recent year with the widespread use of mobile device, Mobile Ad hoc networks (MANETs) technology has been attracted attention day by day. Due to MANETs don't need the infrastructure, it can deploy fast and conveniently in any environment. Because of its easy deployment features, in addition to used in personal area networks, home area networks and so on. Specially, MANETs suit for military operations and the emergent disasters rescue that need to overcome terrain and special purpose in urgent. However the dynamical network topology of MANETs, infrastructure-less property and lack of certificate authority make the security problems of MANETs need to pay more attention. The common routing protocols in current such as DSR AODV and so on almost take account in performance. They don't have the related mechanism about detection and response. Therefore, we proposed a DSR based secure routing protocol in this paper, named BDSR (Baited-Black-hole DSR). The BDSR detects and avoids the black hole attack based on merging proactive and reactive defense architecture in MANET by using the virtual and non-existent destination address to bait the malicious node to reply RREP.
