| Popis: | 96 In this thesis, we propose the Flexible Wireless Sensor Platform (FWSP) which is a standard, verifiable, common approach wireless sensor network management system architecture. The proposed FWSP has the following features: remote internet enabler, reconfiguration by parameter which improve accuracy, dynamic addition of sensor nodes, and fault tolerance which increases the reliability/stability. The significant of our contribution is to establish the adoption of (Commercial, off-the-shelf (COTS) devices, open source, and well known protocols for sensor data management and greatly simplify the development of wireless networks based on new protocol stack. The new protocol stack includes a common controller-hardware (system on module), common control program, common device drivers, common managed objects base, and common appearance to higher-level sensor network management. The proposed FWSP architecture offers flexibility, easy customization, and seamless system integration. An experimental has been established based on wireless communication channel. using wireless Local area network (WLAN) ( IEEE802.11b) as primary communication channel on our prototype sensor node, I2C /Smbus device such as temperature sensors, and desire sensor information can be viewed, and sensor parameter can be adjusted to meet demand. in the thesis. We also proposed a real Medical application. a mobile Patient Monitering System using FWSP as basis called The intelligent wireless based Patient monitering Sensor system (IWPMS, Sensor Node) which improve Vital parameter precision, The goals of the IWPMS are to demonstrate the value, utility of FWSP .A Flexible Framework for Wireless-Based Intelligent Sensor with Reconfigurability, Dynamic Adding, and Web Interface. The proposed mobile Patien platform architecture offers flexibility, easy customization for different vital parameter. An prototype has aslo been established based on wireless communication channel. Using wireless Local arean network ( WAN, IEEE802.11) and WMTS as communication channel on our prototype Sensor node, desire sensor information(vital parameter) can be viewed, and vital parameter can be adjusted to meet demanding. Through the Patient monitoring system. Doctor can getand view the vital life parameter Whether it is an EcG,Blood pressure values,Blood glucose level,plus Oximeter.,etc. |
