Sensor nodes of Wireless Sensor Networks have limited battery power, so energy efficiency is mainly considered in the design. A novel mechanism of intra-cluster data gathering is designed for reducing the energy consumption and prolonging the network lifetime. Firstly, each cluster head acts continuously as local control center and will not be replaced by the candidate cluster head until its op...

Managing power consumption while simultaneously delivering acceptable levels of performance is becoming a critical issue in several application domains such as wireless computing. We integrate compiler-assisted techniques with power-aware operating system services and present scheduling techniques to reduce energy consumption of applications that have deadlines. We show by simulation that our d...

4 Objective: To examine whether home availability of energy-dense snack foods mediates the 5 association between television viewing (TV) and energy-dense snack consumption among 6 adolescents. 7 Design: Cross-sectional. 8 Setting: Secondary schools in Victoria, Australia. 9 Subjects: Adolescents (n=2984) from Years 7 and 9 of secondary school completed a web10 based survey, between September 20...

Cloud computing provides an effective approach to deliver multimedia services to end users with the desired user quality of experience (QoE). However, cloud-based multimedia applications require many of servers and consume huge energy. To reduce energy consumption, a multimedia service provider (MSP) should balance the energy and QoE. In this paper, a theoretic model is developed to explore the...
