This project aims to contribute to education research using mobile apps to demonstrate how signals and systems concepts are used in sensor network localization. An educational demonstration of sensor localization on mobile devices is described with the mobile devices acting as nodes of a sensor network. In our approach, we are developing an app that uses a modified version of time-difference of arrival...
This paper presents a distributed event-region detection scheme for wireless sensor networks. Under the assumption that the event-region detection process follows a stationary distribution, the proposed scheme employs a kind of spatial interpolation, that is Indicator Kriging (IK), to reduce the impact of fault nodes. The approach was composed of two major tasks: (1) an indicator transformation from...
