Reduction of delays in reactive routing protocol for unobservable mobile ad-hoc networks

Privacy-preserving routing is most important for some ad hoc networks that needs stronger privacy protection. In that to describe stronger privacy requirements regarding privacy-preserving routing in mobile ad hoc networks is a most important one. In many of the existing techniques have been proposed to provide privacy in ad hoc networks. The previous technique like Unobservable secure routing scheme USOR to provides complete unlinkability and content unobservability to protect for all types of packets in MANET. US OR protocol uses a novel combination of employing anonymous key establishment based on grou p signature and ID-based encryption for route discovery. However, none of these existing schemes offer how to protect against blackhole attacks, which cannot be prevented with USOR. The proposed scheme is used to avoid the blackhole attacks use of sequence number identification method to reduce the data transfer delays. Also evaluate its performance by comparing with USOR protocol to achieve the high level privacy protection in MANET.
