GradeTrust: A Secure Trust Based Routing Protocol For MANETs

Spread the love

Trust-based secure routing in MANETs has attracted lot of research attention worldwide. It is effective in providing secure routing by isolating malicious nodes and other overheads from MANETs. This paper proposes, GradeTrust, a secure routing protocol for MANETs based on the trust levels of network nodes. It uses trust to isolate black hole routing attacks thus offering secure routing of data traffic as well as improved packet delivery ratio. Preliminary simulation results have shown that trust compromise and packet delivery ratio is better in GradeTrust compared to traditional routing protocols, such as AODV and FSR.
