Comparing Ad IIoc routing protocols in the presence of attacks

With the increased interest in mobile ad hoc networks (MANED there has been a greoter focus on this subiect in the last years. A MANET is a network with no fixed infrastructure. Most of the routing protocols in Ad Hoc networks assume nodes are trustworthy and cooperative. This assumption renders wireless Ad Hoc networks vulnerable to various type of denial of service (DoS) attaclAd Hoc routing protocols, using On-Demand Distance Vector (AODV), Dynamic Source Routing (DSR) and Direct Sequence Distance Vector (DSDV). Their performances under normal condition and in the presence of attaclcs have been compared. Simulation results show that these routing protocols have low performance in the presence of attacks. Alsp DSDV has the worst performance than the others. Although these routing protocols can not be used in military applications, but they have good throughpuls in commercial or other applications that they are not exposed to Denial ofService attacks.
