AB  - In MANET, privacy protecting routing is a big challenge. To overcome this in this study we proposed to design efficient DDoS attack detection techniques for the PPSEER. We mainly consider Sybil and selective forwarding attacks. A legitimate node and a Sybil attack node are differentiated based on their neighborhood joining behavior using RSS. In the proposed solution, the super nodes (deployed in previous work) monitor their upstream and downstream nodes and estimate the RSS and link loss rate. While estimating the loss rate, both the losses in transmission due to bad channel quality and collision in the channel are considered. Each super node maintains a history of packet count for estimating link loss rate which is updated on receiving a packet from upstream node. Then a detection threshold was set up for RSS and link loss rate so as to detect the Sybil attacks and selective forwarding attacks.
