  • 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 ...
  • Analysis of key management in wireless sensor networks 
    Dustin, M.; Shankarappa, J.; Petrowski, M.; Weerasinghe, K.G.H.D.; Fu, H. (IEEE EIT?07, 2007)
    A multitude of wireless sensor networks exist today in various fields, each having a specific objective in mind. Based on the objectives for each network, the security concerns can be different, dependent on such factors ...
  • 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 ...
  • Data centric adaptive in-network aggregation for wireless sensor networks 
    Weerasinghe, K.G.H.D.; Elhajj, I.; Krsteva, A.; Najm, M.A. (IEEE/ASME International Conference, 2007)
    This paper presents and evaluates a data centric adaptive in-network aggregation algorithm for wireless sensor networks. In-Network data aggregation is used in wireless sensor networks to reduce the power consumption of ...
  • 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 ...
  • 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 ...
  • 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. ...
  • Human Perception of Haptic Force Direction 
    Elhajj, I.; Weerasinghe, K.G.H.D.; Dika, A.; Hansen, R. (IROS 2006 IEEE/RSJ International Conference, 2006)
    In this paper we investigate the accuracy of human perception of haptic force direction applied to the hand. Haptic interfaces are commonly used in many applications and understanding the limitations of human perception ...
  • 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 ...
  • 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 ...
