Network Self-Organization In The Internet Of Things, Arjun Athreya, Patrick Tague
Network Self-Organization In The Internet Of Things, Arjun Athreya, Patrick Tague
Patrick Tague
The Internet of Things is a paradigm that allows the interaction of ubiquitous devices through a network to achieve common goals. This paradigm like any man-made infrastructure is subject to disasters, outages and other adversarial conditions. Under these situations provisioned communications fail, rendering this paradigm with little or no use. Hence, network self-organization among these devices is needed to allow for communication resilience. This paper presents a survey of related work in the area of self-organization and discusses future research opportunities and challenges for self-organization in the Internet of Things. We begin this paper with a system perspective of the …
Asia: Accelerated Secure In-Network Aggregation In Vehicular Sensing Networks, Xiao Wang, Patrick Tague
Asia: Accelerated Secure In-Network Aggregation In Vehicular Sensing Networks, Xiao Wang, Patrick Tague
Patrick Tague
Vehicular Ad-Hoc Networks (VANETs) can potentially become a sensing platform. In-network aggregation, a fundamental primitive for querying sensory data, has been shown to reduce overall communication overhead at large. To secure data aggregation in VANETs, existing schemes mainly rely on digital signatures. However, generating and verifying such signatures can cause high computational overhead. More importantly, time-consuming verifications lead to the vulnerability to signature flooding attacks in which a receiver cannot timely verify all messages before their respective deadlines. In this paper, we propose ASIA as an Accelerated Secure In-network Aggregation strategy that can accelerate message verifications and significantly reduce computational …

Location privacy has become one of the critical issues in the smartphone era. Since users carry their phones everywhere and all the time, leaking users’ location information can have dangerous implications. In this paper, we leverage the idea that Wi-Fi parameters not considered to be “sensitive” in the Android platform can be exploited to learn users’ location. Though the idea of using Wi-Fi information to breach location privacy is not new, we extend the basic idea and show that clever attackers can do so without being detected by current malware detection techniques. To achieve this goal, we develop the Unauthorized …
How To Jam Without Getting Caught: Analysis And Empirical Study Of Stealthy Periodic Jamming, Bruce Debruhl, Patrick Tague
How To Jam Without Getting Caught: Analysis And Empirical Study Of Stealthy Periodic Jamming, Bruce Debruhl, Patrick Tague
Patrick Tague
Despite the widespread commercial use of spread spectrum technology, advanced algorithms and modern hardware capabilities still allows efficient denial-of-service attacks against wireless communication systems using jamming. Much of the recent work on jamming mitigation has focused on how to adjust the transmitter-receiver system once a jamming attack has been detected. However, characterizing the detectability of certain classes of jamming attacks remains a largely unstudied problem. We aim to narrow this gap by analyzing the effect of a class of periodic jamming attacks on the attack detection metrics of packet delivery ratio (PDR) and received signal strength (RSS). We show that …
Stochastic Optimization Of Flow-Jamming Attacks In Multichannel Wireless Networks, Yu Seung Kim, Bruce Debruhl, Patrick Tague
Stochastic Optimization Of Flow-Jamming Attacks In Multichannel Wireless Networks, Yu Seung Kim, Bruce Debruhl, Patrick Tague
Patrick Tague
An attacker can launch an efficient jamming attack to deny service to flows in wireless networks by using cross-layer knowledge of the target network. For example, flow-jamming defined in existing work incorporates network layer information into the conventional jamming attack to maximize its attack efficiency. In this paper, we redefine a discrete optimization model of flow-jamming in multichannel wireless networks and provide metrics to evaluate the attack efficiency. We then propose the use of stochastic optimization techniques for flow-jamming attacks by using three stochastic search algorithms: iterative improvement, simulated annealing, and genetic algorithm. By integrating the algorithms into a simulation …
Selfish Manipulation Of Cooperative Cellular Communications Via Channel Fabrication, Shrikant Adhikarla, Min Suk Kang, Patrick Tague
Selfish Manipulation Of Cooperative Cellular Communications Via Channel Fabrication, Shrikant Adhikarla, Min Suk Kang, Patrick Tague

In today’s cellular networks, user equipment (UE) have suffered from low spectral efficiency at cell-edge region due to high interference from adjacent base stations (BSs), which share the same spectral radio resources. In the recently proposed cooperative cellular networks, geographically separated multiple BSs cooperate on transmission in order to improve the UE’s signal-to-interference-plus-noise-ratio (SINR) at cell-edge region. The service provider of the system dynamically assigns the cluster of BSs to achieve higher SINR for the UE while optimizing the use of system radio resources. Although it is the service provider that makes the clustering decision for the UE, the service …
Self-Organization Of A Mesh Hierarchy For Smart Grid Monitoring In Outage Scenarios, Arjun Athreya, Patrick Tague
Self-Organization Of A Mesh Hierarchy For Smart Grid Monitoring In Outage Scenarios, Arjun Athreya, Patrick Tague
Patrick Tague
Current hierarchical communication infrastructure in the smart grid is not robust for data collection from smart meters during outages. In this work, we propose a self-organizing multi-channel wireless communication framework to aid in data collection for smart grid health monitoring. We propose a two-stage bootstrapping process in which nodes first self-organize into local mesh clusters by flattening the provisioned hierarchy and then interconnect to provide mesh connectivity from the outage region to functioning regions of the grid. We propose to construct this mesh-of-meshes hierarchy using a cross-layer strategy that jointly considers medium access limitations and the asymmetric traffic flow that …
