Detection of single and collaborative black hole attack in MANET

Abstract

Ad hoc On Demand Distance Vector (AODV) routing is an extensively accepted routing protocol for Mobile Ad hoc Network (MANET). The inadequacy of security considerations in the design of AODV makes it vulnerable to black hole attack. In a black hole attack, malicious nodes attract data packets and drop them instead of forwarding. Among the existing black hole detection schemes, just a few strategies manage both single and collaborative attacks and that too with much routing, storage and computational overhead. This paper describes a novel strategy to reduce single and collaborative black hole attacks, with reduced routing, storage and computational overhead. The method incorporates fake route request, destination sequence number and next hop information to alleviate the limitations of existing schemes.
