Because air pollutants seriously affect human health, the government in Taiwan attempts to reduce the pollutants by passing many environmental laws and establishing various large-scale and expensive air quality monitoring systems. These monitoring systems are capable of large-scale monitoring, but they cannot immediately detect small-scale air quality changes. Wireless sensor networks are novel monitoring...
Localization is one of the critical tasks of the wireless sensor networks (WSN). Many applications such as environment monitoring, location service and target tracking need the sensors' location. In this paper, we propose a novel range-based distributed localization algorithm - S-MRL (sampling and Malguki refinement localization). Our algorithm is simple and simulation results show our algorithm achieves...
Advances in technologies have resulted in functional extension of wireless sensor nodes. However, high power consumption is still a significant problem needed to be solved in wireless sensor networks (WSN). In this paper, a NODE-RTI model based on the event generation model is proposed. This model provides a solution for a wireless sensor node to make a compromise of power consumption and amount of...
