Battery powered sensors are particularly impractical in under-water pipelines due to limited access. Therefore, harvesting of ambient energy to power embedded sensors is an attractive option for such systems. A method is proposed, in this paper, to power in-pipe wireless sensor nodes based on energy harvesting techniques, with minimal impact to the pipe performance. Based on the initial analysis presented in the paper, models will be developed next to facilitate the design of an energy harvester system for Turkey-Cyprus water pipeline project currently under construction.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125620458","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Data prefetching has been used as a popular method to hide memory latencies by fetching data proactively before the processor needs the data. Fetching data ahead of time from the memory subsystem into faster caches reduces observable latencies or wait times on the processor end and this improves overall program execution times. We study two types of prefetching techniques that are available on a 61-core Intel Xeon Phi co-processor, namely software (compiler-guided) prefetching and hardware prefetching on a variety of workloads. Using machine learning techniques, we synthesize workload phases and the sequence of phase patterns using raw performance data from hardware counters such as memory bandwidth, miss ratios, prefetches issued, etc. Furthermore, we use performance data from workloads with different impacts and behaviors under various prefetcher settings. Our contribution can help in future prefetching design in the following ways: (1) to identify phases within workloads that have different characteristics and behaviors and help dynamically modify prefetch types and intensities to suit the phase; (2) to manage auto setting of prefetcher knobs without great effort from the user; (3) to influence software and hardware prefetching interaction designs in future processors; and (4) to use valuable insights and performance data in many areas such as power provisioning for the nodes in a large cluster to maximize both energy and performance efficiencies.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"90 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125394935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Good knowledge of the sources of energy consumption in WSNs is the first step to reduce energy consumption. Therefore, an accurate energy model is required for the evaluation of communication protocols. In this paper, we provide an energy model for WSNs considering the physical layer and MAC layer parameters by determining the energy consumed per payload bit transferred without error over AWGN channel. We show how the transmission power must be chosen in order to achieve energy-efficient communications over AWGN channel. We also find that, for each modulation scheme, there are optimal transmission power at which the energy consumption is minimized. Moreover, we investigated the energy saving gained from optimizing the constellation size.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"63 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125070804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The circuit structure and the working principle are illustrated. The circuit is capable of providing five different voltage levels at the inductor input with the help of two flying capacitors. The 5-level buck converter can work at different operation regions covering wide range of output voltage values. By reducing the voltage difference at the inductor input, the 5-level buck converter can use smaller inductor compared to both 3-level and conventional buck converters which makes it more suitable for on-chip DC-DC conversion. A test circuit has been implemented in TSMC 65nm technology using 0.5nH on-chip spiral inductor and simulation results show better performance as compared to conventional and 3-level buck converters. For same switching frequency and inductor size, the 5-level buck converter achieves more than a 15% efficiency improvement over a 3-level buck converter at certain output voltage ranges.","PeriodicalId":334594,"journal":{"name":"5th International Conference on Energy Aware Computing Systems & Applications","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132932689","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
