DOS Attack Mitigation In MANET

  Er. Inakshi Garg,  Er. Meenakshi Sharma

Mobile Ad hoc Network is one of the kinds of wireless networks which utilize multi-hop radio relaying and it has no infrastructure Network because of its capability of operating without any support of fixed infrastructure or without any centralized administration. MANET has no clear line to prevent so both legitimate network users and malicious attackers can access it. There are major challenges in MANET in case of malicious nodes; it is to designs the robust security solution which helps to prevent MANET from various DDOS attacks. Security plays a vital role in mobile ad hoc network (MANET) because of its applications like disaster-recovery or battlefield networks. MANETs are more vulnerable as compared to wired networks because lacking of a trusted centralized authority and limited resources. The main objective of this is comparative study of various kinds of DDOS attacks and various detection methods as well as defense mechanisms like Disable IP broadcast detection technique, profile based detection and prevention of DOS attack using target customer behavior and existing solutions to protect MANET protocols. With the help of these techniques no of collisions and packet delievery ratio is also evaluated by comparing two prevention techniques existing prevention technique and proposed prevention technique. The proposed technique increases PDR(packet delievery ratio) and reduces number of collisions.
