Proceedings ArticleDOI
A quantitative trust establishment framework for reliable data packet delivery in MANETs
TL;DR: A trust establishment scheme for MANETs which aims to improve the reliability of packet forwarding over multi-hop routes in the presence of potentially malicious nodes by incorporating an "opinion" metric into ad hoc routing protocols.
Proceedings ArticleDOI
Robust cooperative trust establishment for MANETs
TL;DR: A robust cooperative trust establishment scheme to improve the reliability of packet delivery in MANETs, particularly in the presence of malicious nodes, which is robust against the propagation of false trust information by malicious nodes.
Proceedings ArticleDOI
NetBouncer: client-legitimacy-based high-performance DDoS filtering
TL;DR: The key innovation of the NetBouncer approach is the ability to distinguish legitimate traffic from illegitimate traffic.
Journal ArticleDOI
Accurately Measuring Denial of Service in Simulation and Testbed Experiments
TL;DR: Several DoS impact metrics that measure the quality of service experienced by users during an attack are proposed that map QoS requirements for several applications into measurable traffic parameters with acceptable, scientifically determined thresholds.
Journal ArticleDOI
E-Hermes: A robust cooperative trust establishment scheme for mobile ad hoc networks
TL;DR: This work proposes a robust cooperative trust establishment scheme to improve the reliability of packet delivery in MANETs, particularly in the presence of malicious nodes, and presents simulation results which demonstrate the effectiveness of the proposed scheme.
