基于能耗指导分布式网络分簇路由优化设计

针对传统能耗管理和路由设计模型不能对非均匀分布的异构网络进行自适应能量补给和能量均衡分配的问题,提出一种基于能耗指导的分布式网络分簇路由优化设计方案。对网络模型进行构建,设计异构非均匀分布式网络的能量采集模型和能量消耗模型,以最小网络能耗均衡为指导,设计出优化的网络分簇路由算法。得到基于能耗指导模型的分布式网络路由优化数据分发机制,使网络能耗最低,节点存活性最好,且性能最高。实验结果表明,采用该算法进行分布式网络能耗指导,实现分簇路由优化设计,能够显著降低网络的能耗,有效提高网络生存期和覆盖率,分布式网络的吐吞量也得到提高。

剩余能量相干均衡分簇能耗双阈值分配算法

在计算机多分簇任务执行中,由于初始能量有限,需要对网络分簇能耗进行优化分配,提高任务执行效率。提出基于剩余能量相干均衡的网络分簇能耗双阈值分配算法,算法考虑了节点当前能量、簇成员数量、簇首与节点间距离,设计了能耗指导的分布式网络能量采集和消耗均衡模型,采用收敛性度量值进行路由分配,实现能耗的双阈值分配,在系统的全局任务调度中心将所有任务进行融合,输入系统总调度器,设计剩余能量相干均衡算法,构建能耗分配的双阈值模型,实现网络分簇能耗双阈值分配。实验结果表明,算法能够降低任务调度关键路径延时,提高low-Vt单元使用率,降低相干功耗,形成最优化能耗管理输出,使得系统更加稳定。

To Promote Green Buildings in China: Lessons from the USA and EU

Buildings have contributed to the energy shortage, pollution and global climate change. To promote green buildings is the way access to the sustainable development. Currently, China has issued some regulations and systems to boost the green building. However, problems lie in China and the systems are not effective. USA and EU have rich experiences and fairly sophisticated legislation and policies to develop green building. China may get some lessens from these countries. This paper will make an overview of legal framework and main system of green building in China, then, analyses some important legal systems and typical case related green building in the USA and EU. Further, problems were pointed out in the China based on the comparative analysis of these countries. Lastly, according to the condition in China and lessons from USA and EU, this paper will put some suggests to promote green building, such as, take some measures to enhance the awareness of the stakeholders, create multi- incentive tools and so on.
