Life cycle assessment (LCA) method was used to examine the environmental impact of wheat-maize rotation system emphasizing double high in Quzhou County. The LCA considered the entire system, from raw material extraction to grain production, in arable farming to produce 1 ton each of winter wheat and summer maize. Results indicated that double high agriculture could improve the yield of winter wheat...
Multiple Channel Design (MCD) has been adopted widely in wireless networks to increase throughput and reliability with relatively less energy consumption. Due to physical restrictions of sensor nodes, applying multiple radio channels in sensor networks poses significant challenges, particularly on energy consumption. To address such challenges, we propose an energy-aware MCD scheme called SmartChannel...
This paper addresses energy-efficient data gathering issues in wireless sensor networks (WSNs). Leveraging data correlation in densely-deployed sensor networks, we propose an Energy-aware Probability-based Clustering algorithm (EPC), featuring high scalability and flexibility particularly suitable for large-scale WSNs. Unlike most existing data gathering schemes that construct static routing structures...
This paper presents the results and analysis of a study conducted with the objective of investigating the rural household energy consumption in northwest China domestic sector and the environmental emissions associated with it. For this purpose, we used representative rural villages of Loess Hilly Region for case studie. A sample of the households was surveyed, giving due emphasis to energy consumption...
We propose a novel measure method of information utility for tracking and localization in wireless sensor networks (WSNs). The target moving arbitrarily in WSNs is modeled by Markov chains using a transition matrix. The proposed information utility measurement allows us to expect the next state of the target and identify the informative sensors. Further, compared with existing localization methods,...
