Routing amid Colluding Attackers
Found in: Network Protocols, IEEE International Conference on
By Jakob Eriksson, Michalis Faloutsos, Srikanth V. Krishnamurthy
Issue Date:October 2007
pp. 184-193
We propose the first practical solution to the long-standing problem of secure wireless routing in the presence of colluding attackers. Our secure routing protocol, Sprout, continuously tries new routes to the destination. Routes are probabilistically gene...
 
Privacy Is Dead: Long Live Surveillance Symmetry
Found in: IEEE Internet Computing

Issue Date:January 2011
pp. 81-83
Increasingly, despite the protests and concerns of consumers and consumer advocates, privacy is becoming encroached upon and whittled away. Here, the author offers an unconventional approach on how to handle this loss of privacy and empower the average per...
 
TrueLink: A Practical Countermeasure to the Wormhole Attack in Wireless Networks
Found in: Network Protocols, IEEE International Conference on
By Jakob Eriksson, Srikanth Krishnamurthy, Michalis Faloutsos
Issue Date:November 2006
pp. 75-84
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...
 
Conversion: multi-version concurrency control for main memory segments
Found in: Proceedings of the 8th ACM European Conference on Computer Systems (EuroSys '13)

We present Conversion, a multi-version concurrency control system for main memory segments. Like the familiar Subversion version control system for files, Conversion provides isolation between processes that each operate on their own working copy. A proces...
     
Tracking unmodified smartphones using wi-fi monitors
Found in: Proceedings of the 10th ACM Conference on Embedded Network Sensor Systems (SenSys '12)
By A. B. M. Musa, Jakob Eriksson
Issue Date:November 2012
pp. 281-294
Smartphones with Wi-Fi enabled periodically transmit Wi-Fi messages, even when not associated to a network. In one 12-hour trial on a busy road (average daily traffic count 37,000 according to the state DOT), 7,000 unique devices were detected by a single ...
     
Map inference in the face of noise and disparity
Found in: Proceedings of the 20th International Conference on Advances in Geographic Information Systems (SIGSPATIAL '12)
By Jakob Eriksson, James Biagioni
Issue Date:November 2012
pp. 79-88
This paper describes a process for automatically inferring maps from large collections of opportunistically collected GPS traces. In this type of dataset, there is often a great disparity in terms of coverage. For example, a freeway may be represented by t...
     
Mining large-scale, sparse GPS traces for map inference: comparison of approaches
Found in: Proceedings of the 18th ACM SIGKDD international conference on Knowledge discovery and data mining (KDD '12)
By George Forman, Jakob Eriksson, James Biagioni, Xuemei Liu, Yanmin Zhu, Yin Wang
Issue Date:August 2012
pp. 669-677
We address the problem of inferring road maps from large-scale GPS traces that have relatively low resolution and sampling frequency. Unlike past published work that requires high-resolution traces with dense sampling, we focus on situations with coarse gr...
     
WiFlow: real time travel time estimation using wi-fi monitors
Found in: Proceedings of the 9th ACM Conference on Embedded Networked Sensor Systems (SenSys '11)
By A. B. M. Musa, Jakob Eriksson
Issue Date:November 2011
pp. 429-430
A real-time travel time estimation system is demonstrated that uses Wi-Fi monitors deployed along surface streets to capture Wi-Fi packets from smartphones in passing vehicles. Travel time is estimated based on observations of the same vehicle by two or mo...
     
Tracking transit with EasyTracker
Found in: Proceedings of the 9th ACM Conference on Embedded Networked Sensor Systems (SenSys '11)
By Jakob Eriksson, James Biagioni, Timothy Merrifield, Tomas Gerlich
Issue Date:November 2011
pp. 401-402
EasyTracker is an automated system that assists small public or private transit agencies in deploying bus tracking and arrival time prediction. This demo will showcase how data from GPS sensors embedded in smartphones can be automatically processed in orde...
     
EasyTracker: automatic transit tracking, mapping, and arrival time prediction using smartphones
Found in: Proceedings of the 9th ACM Conference on Embedded Networked Sensor Systems (SenSys '11)
By Jakob Eriksson, James Biagioni, Timothy Merrifield, Tomas Gerlich
Issue Date:November 2011
pp. 68-81
In order to facilitate the introduction of transit tracking and arrival time prediction in smaller transit agencies, we investigate an automatic, smartphone-based system which we call EasyTracker. To use EasyTracker, a transit agency must obtain smartphone...
     
Cooperative transit tracking using smart-phones
Found in: Proceedings of the 8th ACM Conference on Embedded Networked Sensor Systems (SenSys '10)
By Arvind Thiagarajan, Jakob Eriksson, James Biagioni, Tomas Gerlich
Issue Date:November 2010
pp. 85-98
Real-time transit tracking is gaining popularity as a means for transit agencies to improve the rider experience. However, many transit agencies lack either the funding or initiative to provide such tracking services. In this paper, we describe a crowd-sou...
