Structural health monitoring (SHM) is of great significance for ensuring the using functions, safety operation of buildings and extending service lifetime of buildings. The structural damage detection is the main work of the structural health monitoring. In this paper, we proposed a new online structural damage detection method called N-stage Kalman Filter Algorithm (NS-Kalman). Its main idea is to...
Recent advances in computer technology and wireless communications have enabled the emergence of stream-based sensor networks. In such sensor networks, real-time data are generated by a large number of distributed sources. Queries are made that may require sophisticated processing and filtering of the data. A query is represented by a query graph. In order to reduce the data transmission and to better...
This paper presents an algorithm for distributed power control and scheduling over wireless ad hoc-networks, where the data rate on each link depends on the transmission power levels at interfering links (non-convex coupling between link data rates). In this paper, we first consider a K-hop interference model. We describe a message passing algorithm that finds an optimal power allocation (schedule)...
In this correspondence, we consider a wireless sensor network consisting of n sensors, and each sensor has a measurement, which is an integer value belonging to the set {().....m-1}, so that it can be represented by [log2 m] bits. The network has a special node called the fusion center whose goal is to compute a symmetric function of these measurements. The problem studied is to minimize the total...
