Wireless sensor networks solution for space environmental monitoring

摘要

Wireless Sensor Networks (WSNs) is a novel technology in acquiring and processing information and has been an active research area in recent years. Because of the energy constraints of sensor nodes, such systems necessitate an energy-aware design to ensure the longevity of monitoring mission. In this paper, we present a remote space environmental monitoring system using wireless sensor networks. Some key technologies are investigated and discussed in detail. Firstly, the architecture of WSN is provided as well as the component structure of sensor nodes. Then, the key technologies including energy aware routing and localization scheme involved in the system are investigated. By simulation software OMNeT++, we include a performance study demonstrating the advantages of our approach based on simulation study. Simulation results show that the quality of localization is well bounded by the range of communication and the topology control is effective.
