Distributed inversion algorithm for sensor networks

摘要：

Application of sensor networks for monitoring of civil infrastructures is attracting wide interest from research community.Dense measurement is expected to improve monitoring capability,while computational and communication burden would be enormous for large-scale infrastructure.In this paper,a distributed computing algorithm for sensor networks to solve inverse problems are proposed,which utilizes processing and communication capabilities and would add intelligence to the network to overcome these difficulties.The developed algorithm is to obtain source distributions from measurement for physical phenomena,which decay with distance,and its fundamental characteristics are studied in contrast to ordinary centralized computing method.Capability of distributed computing to solve inverse problems using limited measurement information is demonstrated by simulation studies,which would promote the applicability and advantage of sensor networks for monitoring.
