Counter and Network Density Based Detection and Prevention Scheme of DOS Attack in MANET

This paper presents the denial of service attack in MANET using a threshold value. In our approach, the node broadcasts the packets and then finds out the neighbors’. then it checks the degree of each successive neighbor and checks for a threshold value. If value is greater than the value clearly distinguishes between sparse and dense network. After waiting for random no. of slots the counter check is done which decides whether to terminate the process or not and continue ddos attack in manet in each network. It is better than the previous methods.
