Abstract: In mobile ad hoc network, the mobile nodes are susceptible to distributed denial of service attack where more than one node will turn out to be compromised and mislead the other mobile nodes on the MANET. To provide the solution for this problem in MANET, we have already proposed Secure and Efficient Distance Effect Routing Algorithm (SE_DREAM) protocol which is robust against flood attack in MANET. SE_DREAM uses traffic analysis method to discover the flood attack in MANET. In this study, we concentrate on other distributed denial of service attack such as Blackhole, Grayhole and Sybil attack for which we, propose a novel approach O bliging Entice Discovery Approach (OEDA). The OEDA scheme differentiates the attacker nodes from the legitimate nodes by analyzing the address list in the Route Reply (RREP) Packets. OEDA is embedded with existing SE_DREAM protocol to make the path to destination much more robust gainst DDoS attack. The new proposed secure routing protocol is named as improved secure and efficient distance effect routing algorithm. OEDA approach detects numerous malicious nodes concurrently present in MANETs. Simulation results show that our improved SE_DREAM outperform the SE_DREAM in the presence of malicious nodes in MANET.
