Collaborative assessment of functional reliability in wireless networks
2012 IEEE 9th International Conference on Mobile Ad-Hoc and Sensor Systems (MASS)
By Zi Feng,Konstantinos Pelechrinis,Srikanth Krishnamurthy,Ananthram Swami,Felix Wu,Munindar P. Singh
Issue Date:October 2012
Nodes that are part of a multihop wireless network, typically deployed in mission critical settings, are expected to perform specific functions. Establishing a notion of reliability of the nodes with respect to each function (referred to as functional reli...
TrueLink: A Practical Countermeasure to the Wormhole Attack in Wireless Networks
Network Protocols, IEEE International Conference on
By Jakob Eriksson, Srikanth Krishnamurthy, Michalis Faloutsos
Issue Date:November 2006
In a wormhole attack, wireless transmissions are recorded at one location and replayed at another, creating a virtual link under attacker control. Proposed countermeasures to this attack use tight clock synchronization, specialized hardware, or overhearing...
An Integrated Scheme for Fully-Directional Neighbor Discovery and Topology Management in Mobile Ad hoc Networks
IEEE International Conference on Mobile Adhoc and Sensor Systems Conference
By Ece Gelal, Gentian Jakllari, Srikanth Krishnamurthy, Neal Young
Issue Date:October 2006
With directional antennas, it is extremely important that a node maintains information with regards to the positions of its neighbors. This would allow the node to
Handling Asymmetry in Power Heterogeneous Ad Hoc Networks: A Cross Layer Approach
Distributed Computing Systems, International Conference on
By Vasudev Shah, Srikanth Krishnamurthy
Issue Date:June 2005
Power heterogeneous ad hoc networks are characterized by link layer asymmetry: the ability of lower power nodes to receive transmissions from higher power nodes but not vice versa. This not only poses challenges at the routing layer, but also results in an...
