Indoor Monitoring Applications Using Fixed and Mobile Wireless Sensors

Abstract

This paper proposes the idea of a wireless sensor network with applicability in monitoring systems. The goal of the project is to build a monitoring system capable of data gathering which can benefit from both characteristics of fixed and mobile nodes. To become flexible, the mobile node has a modular structure with four levels. The flexibility offered by the mobile nodes increases the performance of the entire data acquisition system. These act as autonomous devices that cooperatively monitor physical or environmental conditions. In order to implement the data acquisition and communication functions, the solution we agreed on has been to use the MTS400 sensor board. Mobile nodes communicate to a central node individual data and statistical indicators over a period. The proposed energy-aware architecture was tested and validated in an indoor experiment.
