Scheduling the sensors active and sleep period is significantly important for achieving energy efficiency in resource constrained Wireless Sensor Networks (WSNs). Most existing node scheduling schemes consider only the energy efficiency of sensor nodes and cannot be used for mobility-centric applications since they are designed for static network topology. Though a few node scheduling schemes a...

For conserving the power of mobile terminals and to support battery powered mobile broadband wireless access devices efficiently IEEE 802.16e defines a sleep mode operation. By regulating the sleep parameters of the IEEE 802.16e such as starting sleep time, initial sleep window size, minimum sleep interval, maximum sleep interval and listen window size the energy can be efficiently utilized. Th...

Energy efficiency is amajor concern inmodern high performance computing (HPC) systems and a poweraware scheduling approach is a promising way to achieve that. While there are a number of studies in power-aware scheduling by means of dynamic power management (DPM) and/or dynamic voltage and frequency scaling (DVFS) techniques, most of them only consider scheduling at a steady state. However, HPC...

We research the topological control of the combination of the clustering hierarchical structure and sleep scheduling mechanism. Firstly, present a inner-cluster node scheduling algorithm solution of inner-cluster connectivity coverage problem, which can meet user’s expected coverage,avoiding the influence of mobile node location. Based on coverage analysis theory, deducts smallest mobile nodes ...
