报告题目:Angle-Based Sensor Network Localization
报告人:井冈山博士
报告摘要:In this talk, I will introduce angle rigidity theory and show how it can be applied to angle-based sensor network localization (ASNL). The ASNL problem is to determine locations of all sensors in a sensor network, given locations of partial sensors (called anchors) and angle measurements obtained in the local coordinate frame of each sensor. Both centralized and distributed settings are considered, respectively. The centralized ASNL is formulated as a rank-constrained semidefinite program (SDP) in either a noise-free or a noisy scenario, with a decomposition approach proposed to deal with large-scale ASNL. The distributed protocol for ASNL is designed based on inter-sensor communications. Graphical conditions for equivalence of the rank-constrained SDP and a linear SDP, decomposition of the SDP, as well as the validity of the distributed protocol, are proposed, respectively. Simulation examples are provided to validate effectiveness of the obtained theoretical results.
