Black Hole Detection Using Modified Sequence Number in Vehicular Ad-hoc Network

Vehicular Ad-hoc Network (VANET) is a type of wireless network with Dedicated Short-Range Communication (DSRC) that enables communication between vehicles (V2V) and to infrastructure around them (V2I). VANET has several security requirements consider in order maintain the functionality. Availability most important requirement due its responsibility maintaining functionality network, attack on availability may cause lack reduce efficiency VANET. One threat black hole. In this paper, we address problem hole VANET, using Modified Sequence Number (MSN) as detection method. The simulation performed NS-2 simulator AODV routing protocol. Detection Rate (DR) False Alarm (FAR) are used evaluate performance MSN algorithm detecting attack. Evaluation variation number CBR packets shows successfully detects attacks DR values reaching 69.0909% at 10 FAR 0.0037 20 packets. We also variations node density. evaluation 100% density nodes, percentage 0% all numbers
