On the design of energy efficient environment monitoring station and data collection network based on ubiquitous wireless sensor networks
2015
In the context of ubiquitous wireless sensor network, this paper presents a framework for wireless sensor networks (WSNs) designed to observe impacts of climate change in crop fields. We propose a system architecture for ubiquitous WSNs for monitoring automatically and continuously in real-time. A prototype system includes two base stations and several sensor nodes which are powered by solar cell are designed and implemented. Climatic parameters from sensor nodes are sent via WSN to the base station, while base station communicates with remote data server center through GPRS/3G network. By using multiple methods of communication, it could enable monitor areas where not in GPRS/3G coverage. With advantages of low-cost and ubiquitous monitoring, the system can be applied widely in agriculture in developing countries like Vietnam. Power consumption estimation and NS-2 simulation results prove the energy efficient of environment stations and data collection networks.
