Towards Efficient Dynamic Uplink Scheduling over Multiple Unknown Channels
Shuang Wu, Xiaoqiang Ren, Qing-Shan Jia +2
Age-of-Information (AoI) is a critical metric for network applications. Existing works mostly address optimization with homogeneous AoI requirements, which is different from practi…
How to Secure Distributed Filters Under Sensor Attacks
Xingkang He, Xiaoqiang Ren, Henrik Sandberg +1
We study how to secure distributed filters for linear time-invariant systems with bounded noise under false-data injection attacks. A malicious attacker is able to arbitrarily mani…
Secure distributed filtering for unstable dynamics under compromised observations
Xingkang He, Xiaoqiang Ren, Henrik Sandberg +1
In this paper, we consider a secure distributed filtering problem for linear time-invariant systems with bounded noises and unstable dynamics under compromised observations. A mali…
Secure State Estimation with Byzantine Sensors: A Probabilistic Approach
Xiaoqiang Ren, Yilin Mo, Jie Chen +1
This paper studies static state estimation in multi-sensor settings, with a caveat that an unknown subset of the sensors are compromised by an adversary, whose measurements can be…
Max-Min Fair Sensor Scheduling: Game-theoretic Perspective and Algorithmic Solution
Shuang Wu, Xiaoqiang Ren, Yiguang Hong +1
We consider the design of a fair sensor schedule for a number of sensors monitoring different linear time-invariant processes. The largest average remote estimation error among all…
Learning Optimal Scheduling Policy for Remote State Estimation under Uncertain Channel Condition
Shuang Wu, Xiaoqiang Ren, Qing-Shan Jia +2
We consider optimal sensor scheduling with unknown communication channel statistics. We formulate two types of scheduling problems with the communication rate being a soft or hard…
Optimal Scheduling of Multiple Sensors with Packet Length Constraint
Shuang Wu, Xiaoqiang Ren, Subhrakanti Dey +1
This paper considers the problem of sensory data scheduling of multiple processes. There are independent linear time-invariant processes and a remote estimator monitoring all t…
Attack Allocation on Remote State Estimation in Multi-Systems: Structural Results and Asymptotic Solution
Xiaoqiang Ren, Junfeng Wu, Subhrakanti Dey +1
This paper considers optimal attack attention allocation on remote state estimation in multi-systems. Suppose there are independent systems, each of which has a remote…
Infinite Horizon Optimal Transmission Power Control for Remote State Estimation over Fading Channels
Xiaoqiang Ren, Junfeng Wu, Karl H. Johansson +2
Jointly optimal transmission power control and remote estimation over an infinite horizon is studied. A sensor observes a dynamic process and sends its observations to a remote est…
Quickest Change Detection in Adaptive Censoring Sensor Networks
Xiaoqiang Ren, Karl H. Johansson, Dawei Shi +1
The problem of quickest change detection with communication rate constraints is studied. A network of wireless sensors with limited computation capability monitors the environment…
Quickest Change Detection with a Censoring Sensor in the Minimax Setting
Xiaoqiang Ren, Jiming Chen, Karl H. Johansson +1
The problem of quickest change detection with a wireless sensor node is studied in this paper. The sensor that is deployed to monitor the environment has limited energy constraint…
