- Remote Weather & Environment Monitoring System in Local Area Using Query Based Flooding Routing Protocol
- Abstract
- A wireless field server is designed to measure and monitor abrupt weather variations in real time in local mountainous terrains where weather changes drastically. The wireless field server is developed as a portable system which can be deployed in mountain valley, small river, and a hard place to approach in wireless sensor network communication environment. Reliable data acquisition and transmission from the deployed field servers in the local area is essential to disaster prevention system. Weather-related information such as temperature, humidity, illumination, atmospheric pressure, and dew point are collected from the designated field server at regular intervals. The measured data from the multiple sensors located in the sensor field is transmitted by the proposed flooding routing protocol to gateway through multi-hop in wireless sensor network. In addition, field servers can be energy efficiently controlled by connected PC to conserve the energy of field servers through query system, depending on the situation. A query system is implemented using Java program to run on a server PC, connected serially via RS-232 protocol to the base station. The proposed flooding routing protocol using query system improves energy efficiency and reliable data transmission for environment monitoring system in local area.
