Hash Function based MAC Protocol to cope with MAC Layer Misbehavior in Manets
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 8
Abstract
Mobile adhoc networks consist of mobile nodes connected by wireless links without using any preexisting infrastructure. MANET nodes rely on network cooperation schemes to properly work, forward traffic unrelated to its own use. However in real world most of the nodes misbehave in order to gain extra bandwidth. Therefore detecting these nodes and providing countermeasure is essential for network performance. This paper proposes a scheme called Hash Function based MAC protocol (HsF-MAC) to cope with backoff cheating technique. HsF-MAC allows MANET nodes to recalculate the backoff value and immediately detect the misbehaving nodes along with effective countermeasure. Moreover colluding behavior (two nodes trying to misbehave collectively) is also detected.
