In this paper, we evaluate the effect security features have on power consumption of such WSNs and revisit the previous conclusions regarding the energetic cost of security. We approach the problem of estimating the cost of security from a highly practical standpoint, and show that many real world, security agnostic factors affect the energy consumption of a device, but are often neglected by security researchers. Consequently, overpriced conclusions are often made that may affect decisions if security features should be by default enabled in real deployments. Our experimental results show that for practical applications and implementations security features introduce a negligible degradation that is often acceptable even for the most energy stringent systems, such as those based on energy harvesting.","PeriodicalId":416168,"journal":{"name":"2014 3rd Mediterranean Conference on Embedded Computing (MECO)","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127740077","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}

Main focus is on small memory requirements while preserving the needed accuracy. Starting from a pair of stereo images, the co-processor computes the “disparity map” used to define corresponding points on the two images. The approach follows the well-known scheme for string alignment by Needleman & Wunsch, commonly used in bioinformatics. The architecture, highly modular, was designed by using Bluespec SystemVerilog development tool and is described in detail. Synthesis results for several FPGA platforms are shown. The actual circuit is an updated version of SASC design. Performance is benchmarked against the former implementation as well as against two reference software versions.","PeriodicalId":416168,"journal":{"name":"2014 3rd Mediterranean Conference on Embedded Computing (MECO)","volume":"59 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129425402","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}

In this paper we show the benefit in terms of performance gain and power reduction of the dynamic adaptation (e.g., cache size, clock frequency, and core issue-width) of an embedded platform, through a design space exploration campaign, and focusing on a relevant case study. To this end, we analyze a set of benchmarks belonging to the embedded application domain with the aim of illustrating how the appropriate selection of reconfiguration instants can positively influence system performance and power consumption. Experimental results using the cjpeg benchmark show that power consumption can be reduced by an average of 22%. Our methodology can be used to create a set of run-time management policies for driving the adaptation process.","PeriodicalId":416168,"journal":{"name":"2014 3rd Mediterranean Conference on Embedded Computing (MECO)","volume":"109 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129271206","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}

In this paper we further develop the ideas presented in [1]. In [1] we consider two problems from linear algebra, namely set intersection problem and scalar product problem and make comparisons to the frequent itemset mining task.

On the other hand, with the large number of nodes in a network, a collective intelligence approach comes into focus for solving various issues. However, as node density and number increases various related problems comes into focus, such as increased RF interference on physical layer, large number of hops in data routing and the overall coverage area issue. All of these parameters are the result of WSN node deployment strategy and their influence on QoS cannot be neglected. To analyze this problem the paper simulated the behavior of large-scale WSN (up to 1000 nodes using OMNeT++) randomly deployed over an area of interest, based on deployment parameters (coverage area, number of nodes and TX power) and in respect to QoS metrics. From simulation results it can be concluded that deployment parameters substantially affects the QoS that a network can support. By choosing optimal deployment parameters it is possible to maximize QoS in a network.","PeriodicalId":416168,"journal":{"name":"2014 3rd Mediterranean Conference on Embedded Computing (MECO)","volume":"231 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-06-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123259676","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}
