Efficient technique to Detect Blackhole Attack in Mobile Ad Hoc Networks

Abstract

An ad hoc routing protocol is a pattern, or standard, that controls to routepackets between mobile devices in a mobile ad hoc network. A new node announces its presence and listens for announcements broadcast by its neighbours. To communicate one node to another one, each node can act as both host as well as router at the same time and perform all the routing and state maintenance operations. Source routing allows a sender of a packet to partially or completely specify the route the packet takes through the network. Source routing allows easier troubleshooting, improved traceroute, and enables a node to discover all the possible routes to a host. Opportunistic data forwarding has not been widely utilized in MANETs, because the lack of an efficient lightweight proactive source routing capability. A lightweight Table Driven Source Routing (TDSR) protocol can maintain more network topology information than Distance Vector (DV). To facilitate source routing and also smaller overhead than DV-based protocols, Link State (LS) and reactive source routing protocols.The threats to users of wireless technology have increased as the service has become more popular.Because of the dynamically changing topology, open environment and lack of security infrastructure, a mobile ad hoc network (MANET) is susceptible to the presence of malicious nodes and to ad hoc routing attacks. The variety of routing attacks that target the weakness of MANETs.In proposed scheme, efforts on mobile ad hoc network's routing weakness and analyzes the network performance under black hole attack that can easily be employed against the mobile ad hoc network (MANET). The resistive schemes against these attacks were proposed for Table Driven Source Routing (TDSR) protocol and the effectiveness of the schemes is validated using NS2 simulations.
