Preventing Cooperative Black Hole Attacks in Mobile Ad Hoc Networks: Simulation Implementation and Evaluation

Weerasinghe, K.G.H.D.; Fu, H. (International Journal of Software Engineering and Its Applications, 2008)

A black hole attack is a severe attack that can be easily employed against routing in mobile ad hoc networks. A black hole is a malicious node that falsely replies for any route requests without having active route to ...
forecasting exchange rates using artificial neural networks

Chandrasekara, N.V.; tilakaratne, C.D. (Journal of Applied Statistics, 2009)
ESAP: Efficient and scalable authentication protocol with conditional privacy for secure vehicular communications

Weerasinghe, K.G.H.D.; Fu, H. (GLOBECOM Workshops (GC Wkshps), 2010 IEEE, 2010)

Security mechanisms such as authentication, message integrity, and non-repudiation are extremely important features for both vehicle-to-vehicle and vehicle-to-infrastructure communications in vehicular ad hoc networks. ...
Enhancement of IEEE 802.11 modules in ns-2 and performance evaluation with error rate

Jin, K.; Weerasinghe, K.G.H.D.; Fu, H. (Proceedings of 43rd Annual Simulation Symposium (ANSS), 2010)

Ns-2 is being widely utilized to evaluate the wired and wireless networks on many research activities. The ns-2.33 distribution version includes an extension of IEEE 802.11 module which improves the core functions of 802.11 ...
An Enhanced Multi-Channel MAC for the IEEE 1609.4 Based Vehicular Ad Hoc Networks

Wang, Q.; Leng, S.; Fu, H.; Zang, Y.; Weerasinghe, K.G.H.D. (INFOCOM IEEE Conference on Computer Communications Workshops, 2010)

This paper proposes a multi-channel MAC scheme for Vehicular Ad Hoc Networks (VANETs), which dynamically adjusts the intervals of Control Channel (CCH) and Service Channels (SCHs). Markov modeling is conducted to optimize ...
Verifying position and velocity for vehicular ad-hoc networks

Weerasinghe, K.G.H.D.; Tackett, R.; Fu, H. (Security and Communication Networks, 2011)

In the near future, vehicle-to-vehicle and vehicle-to-roadside infrastructure communications will enable numerous applications, such as collision avoidance, traffic management, location-based services, and infotainment for ...
Anonymous service access for Vehicular Ad hoc Networks

Weerasinghe, K.G.H.D.; Fu, H.; Leng, S. (Information Assurance and Security (IAS), 2010 Sixth International Conference, 2011)

Communications through road side units in Vehicular Ad hoc Networks (VANETs) can be used to track the location of vehicles, which makes serious threat on users' privacy. In this paper, we propose and evaluate a novel ...
Enhancing unlinkability in Vehicular Ad Hoc Networks

Weerasinghe, K.G.H.D.; Huirong, F. (Intelligence and Security Informatics (ISI), 2011 IEEE International Conference, 2011)

Communication messages in Vehicular Ad-hoc Networks (VANETs) can be used to track movement of vehicles. In this paper, we address the problem of movement tracking and enhance location privacy without affecting security and ...
