Infection Spreading and Source Identification: A Hide and Seek Game
Wuqiong Luo, Wee Peng Tay, Mei Leng
The goal of an infection source node (e.g., a rumor or computer virus source) in a network is to spread its infection to as many nodes as possible, while remaining hidden from the…
On the Universality of Jordan Centers for Estimating Infection Sources in Tree Networks
Wuqiong Luo, Wee Peng Tay, Mei Leng
Finding the infection sources in a network when we only know the network topology and infected nodes, but not the rates of infection, is a challenging combinatorial problem, and it…
Distributed localization of a RF target in NLOS environments
Wenjie Xu, Francois Quitin, Mei Leng +2
We propose a novel distributed expectation maximization (EM) method for non-cooperative RF device localization using a wireless sensor network. We consider the scenario where few o…
Distributed Local Linear Parameter Estimation using Gaussian SPAWN
Mei Leng, Wee Peng Tay, Tony Q. S. Quek +1
We consider the problem of estimating local sensor parameters, where the local parameters and sensor observations are related through linear stochastic models. Sensors exchange mes…
How to Identify an Infection Source with Limited Observations
Wuqiong Luo, Wee Peng Tay, Mei Leng
A rumor spreading in a social network or a disease propagating in a community can be modeled as an infection spreading in a network. Finding the infection source is a challenging p…
Modified CRB for Location and Velocity Estimation using Signals of Opportunity
Mei Leng, Wee Peng Tay, Chong Meng Samson See +2
We consider the problem of localizing two sensors using signals of opportunity from beacons with known positions. Beacons and sensors have asynchronous local clocks or oscillators…
