Seirios: Leveraging Multiple Channels for LoRaWAN Indoor and Outdoor Localization
Jun Liu, Jiayao Gao, Sanjay Jha +1
Localization is important for a large number of Internet of Things (IoT) endpoint devices connected by LoRaWAN. Due to the bandwidth limitations of LoRaWAN, existing localization m…
All Infections are Not Created Equal: Time-Sensitive Prediction of Malware Generated Network Attacks
Zainab Abaid, Dilip Sarkar, Mohamed Ali Kaafar +1
Many techniques have been proposed for quickly detecting and containing malware-generated network attacks such as large-scale denial of service attacks; unfortunately, much damage…
Nephalai: Towards LPWAN C-RAN with Physical Layer Compression
Jun Liu, Weitao Xu, Sanjay Jha +1
We propose Nephalai, a Compressive Sensing-based Cloud Radio Access Network (C-RAN), to reduce the uplink bit rate of the physical layer (PHY) between the gateways and the cloud se…
Health Access Broker: Secure, Patient-Controlled Management of Personal Health Records in the Cloud
Zainab Abaid, Arash Shaghaghi, Ravin Gunawardena +3
Secure and privacy-preserving management of Personal Health Records (PHRs) has proved to be a major challenge in modern healthcare. Current solutions generally do not offer patient…

Gwardar: Towards Protecting a Software-Defined Network from Malicious Network Operating Systems
Arash Shaghaghi, Salil S. Kanhere, Mohamed Ali Kaafar +1
A Software-Defined Network (SDN) controller (aka. Network Operating System or NOS) is regarded as the brain of the network and is the single most critical element responsible to ma…
Software-Defined Network (SDN) Data Plane Security: Issues, Solutions and Future Directions
Arash Shaghaghi, Mohamed Ali Kaafar, Rajkumar Buyya +1
Software-Defined Network (SDN) radically changes the network architecture by decoupling the network logic from the underlying forwarding devices. This architectural change rejuvena…
WedgeTail: An Intrusion Prevention System for the Data Plane of Software Defined Networks
Arash Shaghaghi, Mohamed Ali Kaafar, Sanjay Jha
Networks are vulnerable to disruptions caused by malicious forwarding devices. The situation is likely to worsen in Software Defined Networks (SDNs) with the incompatibility of exi…
Towards Policy Enforcement Point as a Service (PEPS)
Arash Shaghaghi, Mohamed Ali, Kaafar +3
In this paper, we coin the term Policy Enforcement as a Service (PEPS), which enables the provision of innovative inter-layer and inter-domain Access Control. We leverage the archi…
Sparsity based Efficient Cross-Correlation Techniques in Sensor Networks
Prasant Misra, Wen Hu, Mingrui Yang +2
