Nguyen, Hoang (2010-07)We consider the problem of identifying insider-based attacks in the form of jammers in multi-channel wireless networks, where jammers have the inside knowledge of frequency hopping patterns and any protocols used in the ...
iDSRT: Integrated Dynamic Soft Real-time Architecture for Critical Infrastructure Data Delivery over WLAN Nguyen, Hoang; Rivas, Raoul; Nahrstedt, Klara (2008-04)Critical Infrastructures (CIs) such as the Power Grid play an important role in our lives. Of all important aspects of CIs, real-time data delivery is the most important one because appropriate decisions cannot be made ...
He, Wenbo; Nguyen, Hoang; Liu, Xue; Nahrstedt, Klara; Abdelzaher, Tarek F. (2007-12)Data aggregation is an efficient mechanism widely used in wireless sensor networks (WSN) to collect statistics about data of interests. However, the shared-medium nature of communication makes the WSNs are vulnerable to ...
He, Wenbo; Liu, Xue; Nguyen, Hoang; Nahrstedt, Klara; Abdelzaher, Tarek F. (2006-09)A wireless sensor network (WSN) is an ad-hoc network composed of small sensor nodes deployed in large numbers to sense the physical world. Wireless sensor networks have very broad application prospects including both ...
He, Wenbo; Nguyen, Hoang; Liu, Xue; Nahrstedt, Klara; Abdelzaher, Tarek F. (2006-11)Data aggregation is an efficient mechanism to collect statistics of data in wireless sensor networks. However, the shared-medium nature of communication facilitates eavesdropping and packet tampering/injection by adversaries. ...
Topology Control for Maintaining Network Connectivity and Maximizing Network Capacity Under the Physical Model Gao, Yan; Hou, Jennifer C.; Nguyen, Hoang (2007-05)In this paper we study the issue of topology control under the physical Signal-to-Interference-Noise-Ratio (SINR) model, with the objective of maximizing network capacity. We show that existing graph-model-based topology ...
