The paper, “Adaptive Federated Learning in Resource Constrained Edge Computing Systems,” published in IEEE Journal on Selected Areas in Communications, vol. 37, no. 6, pp. 1205-1221, Jun. 2019, is one of the first papers to rigorously study the optimization of federated learning tasks in the wireless edge network environment. Congrats to the whole team!
Paper on a better cascading failure model (CAMPR project) accepted to TPWRS
The paper, “Inclusion of Pre-Existing Undervoltage Load Shedding Schemes in AC-QSS Cascading Failure Models“, talks about improving the accuracy of AC-QSS based models of cascading failures in power grid by incorporating the effects of a built-in protection scheme (undervoltage load shedding) that will be activated in a distributed and autonomous manner during cascading. Congrats to […]
Paper on CAMPR project accepted to ICCCN’21
The paper, Budget-Constrained Reinforcement of SCADA for Cascade Mitigation, examines the problem of communication network design for monitoring and controlling a coupled power grid from the perspective of budgeted allocation of non-PLCC links. Congratulations to Vaji!
Paper on “Queuing Network Topology Inference” accepted to IFIP Networking’21
This work, Queuing Network Topology Inference Using Passive Measurements, studies for the first time the topology inference problem based on possibly uncorrelated end-to-end delay measurements originating from a single source. Compared to existing works using various kinds of active probing mechanisms, we take a very different approach of inferring the detailed queuing dynamics inside the […]
Paper on “attack against network tomography” accepted to TNSE
The paper, Stealthy DGoS Attack against Network Tomography: The Role of Active Measurements, extends our previous works on DGoS Attack by incorporating a defense mechanism through the design of measurement paths to mitigate the performance impact of stealthy attacks. This is the first work on defense against data manipulation attacks on network tomography, which has […]
Paper on “AC-QSS Cascading Failure Model” accepted to PESGM’21
The paper, “A More Realistic AC-QSS Cascading Failure Model with Decentralized UVLS and Centralized RAS“, develops a more realistic cascading failure model for power grid that incorporates the effects of Under Voltage Load Shedding (UVLS) and Remedial Action Scheme (RAS). The work is part of the CAMPR project.
Paper on “Stealthy DGoS Attack” accepted to ToN
Daniel’s work on “Stealthy DGoS Attack: DeGrading of Service under the Watch of Network Tomography” is accepted to IEEE/ACM Transactions on Networking. Congratulations to Daniel on your first journal paper with me! This is the extended version of our earlier INFOCOM’20 paper with the same title, discussing the optimal attack strategies and the maximum damage […]
Paper on “Online Learning of Facility Locations” accepted to ALT’21
This is a joint work with UCL and IBM, on an online version of the classic Facility Location Problem with applications on service placement in mobile edge computing, funded by the DAIS-ITA program. Congratulations to the team!
Paper on “Attack Resilience of Cache Replacement Policies” accepted to INFOCOM’21
The paper uses TTL approximation to analyze the attack resilience of a number of state-of-the-art cache replacement policies (including several two-staged policies), in terms of how well they preserve the hit ratio for legitimate flows under a given number and rates of attack flows. Observing that no single policy is optimal under all kinds of […]
Paper on “Service Placement for Collaborative Edge Applications” accepted to TON
The paper, in collaboration with Lin Wang et al., formulates and solves a novel type of service placement in edge computing designed to support collaborative applications (e.g., social VR), which require not only communications between each user and its service entity, but also between the service entities of users. It is an extended version of […]
