Advancement in wireless communication and miniature electromechanical systems (MEMSs) have enabled the development of low-cost, low power, multi-functional, tiny sensor nodes that can sense the environment, perform data processing, and communicate with each other untethered over short distances. Most of the applications deployed over WSNs require strong coverage requirements, especially those related to the detection and tracking of distributed events. Moreover, these events are forwarded to the analysis center(s) through a set of sink nodes that locally gather data emanating from the elementary sensors. This paper proposes a coverage control scheme that adapts to the situation where multiple sink nodes are deployed within the monitored area. On the opposite to traditional coverage approaches that aim at guaranteeing a uniform density distribution, we place the sensor nodes in a manner that increases the coverage degree according to their proximity to a sink node. To reduce the complexity of the optimization process, we consider a discrete search space by structuring the monitored into a uniform grid. An evolutionary algorithm is then used to choose whether to activate or not sensor nodes within every cell of the grid. We conducted a set of simulations in order to evaluate the performance of the proposed strategy, mainly in ensuring multi-target tracking.","PeriodicalId":352946,"journal":{"name":"ACS/IEEE International Conference on Computer Systems and Applications - AICCSA 2010","volume":"64 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133504803","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}

Technological means are now available for realizing this “anywhere anytime” low-cost wireless access whereby un-utilized wireless resources can be harnessed to form a collaborative network for public access. The success of such access facilities depend largely on the provisioning of fast authentication among the access points. This is crucial for supporting real-time applications such as Voice Over IP (VoIP). In our earlier work, we had developed an inter-domain fast authentication scheme based on the concept of “trust-clouds”. A trust-cloud is formed among neighbouring access points based on a relationship among the owners of the access points. Fast authentication among these inter-domain sites is achieved through cooperation among the trust-cloud members. In previous work, we theoretically formulated the concept of trust-clouds. In this paper we report on the implementation and experimental results of the “trust-clouds” fast authentication concept on legacy hardware. The experimental results verify that the trust-cloud framework can yield significant delay gains for the authentication process when handing off between administrative domains. It is also shown that no special computing platform is needed to achieve these benefits, indeed our testbed was implemented on low end hardware.","PeriodicalId":352946,"journal":{"name":"ACS/IEEE International Conference on Computer Systems and Applications - AICCSA 2010","volume":"87 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134063775","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}

Fuzzy logic represents an exciting technology with a wide scope for potential applications. There is a growing interest both in the field of fuzzy logic computing and in the financial world in explaining the use of fuzzy logic to forecast the future changes in prices of stocks, exchange rates, commodities, and other financial time series. Fuzzy algorithms are intensively used for the identification of dynamic models, combining both numerical and heuristic knowledge. Fuzzy logic provides a remarkably simple way to draw definite conclusions from vague, ambiguous or imprecise information. In this paper, we are investigating the ability of Fuzzy logic (FL) to tackle the financial time series forecasting problems. Experimental results on set of applications indicated that fuzzy logic can effectively solve these types of problems. In order to examine the effectiveness of fuzzy logic applied to forecasting, the comparison with Artificial Neural Networks (ANNs) is performed.","PeriodicalId":352946,"journal":{"name":"ACS/IEEE International Conference on Computer Systems and Applications - AICCSA 2010","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122839663","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}

This paper presents a novel Geocast technique with the hole detection in the geocast region for underwater environment. The proposed model named as Routing and Multicast Tree based Geocasting (RMTG) has been designed for underwater sensor networks. Here we propose a theoretical model for underwater geocasting RMTG that uses greedy forwarding and previous hop handshaking to route the packets towards the geocast region. This technique further disseminates the data within the geocast region by creating a multicast shortest path tree. The technique also proposes a method of hole detection inside the geocast region and a virtual area based routing around the boundaries of the geocast region to reach the geocast region from opposite side. This model provides an efficient geocast technique in terms of node mobility handling, lesser memory utilization, lesser calculations and a better end to end latency. In addition to this the proposed model does not use flooding inside the geocast region that is used in most of the geocasting techniques and also for guaranteed data delivery inside the geocast region, the proposed model does not use the planarization graph concepts.","PeriodicalId":352946,"journal":{"name":"ACS/IEEE International Conference on Computer Systems and Applications - AICCSA 2010","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130584408","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}

This progress is everywhere, at the level of technologies and computer architectures, at the middleware level, at the algorithm and application level, and even at the level of computing paradigms, where we evolved from mainframes, to vector and parallel computers, to grids and clouds, recently. We successfully optimized our algorithms and mapped them to the underlying architecture, e.g. with overlapping communication with computation, better load balancing through domain decomposition into parallel processes, or using library routines optimized for the specific architecture and processors. In our presentation, we will concentrate on the use of grid and cloud technologies for HPC, focusing on the European EU-funded DEISA Distributed European Infrastructure for Supercomputing Applications project, analyzing different HPC loads and their suitability for grids and for clouds, and taking a closer look at lessons learned and recommendations on how to build sustainable e-Infrastructures for computational sciences and engineering in the future.","PeriodicalId":352946,"journal":{"name":"ACS/IEEE International Conference on Computer Systems and Applications - AICCSA 2010","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-05-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130590487","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}
