Scheduling scientific workflows modeled by Directed Acyclic Graphs is an NP complete problem. In cloud environment, there are fluctuations in resource availability due to shared resources and vastly varying workloads. The performance variations in virtual machines, have an impact on task execution times and data transfer times. This has a great impact on the performance of scheduling algorithms. Schedulers should map tasks to cloud resources considering the effective utilization of underlying resources. We propose a new static workflow scheduling algorithm called Predictive Probabilistic Resource Availability based Cloud Workflow Scheduling (PPRA) with the objective of minimizing makespan considering the probability of resource availability of cloud resources. This algorithm is compared with existing algorithms which assume full resource availability while making scheduling decisions. The proposed algorithm is found to be more reliable and performing better than existing HEFT and ECTS algorithms, in terms of minimized makespan.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84233357","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}

Sensor node localization is one of research hotspots in the applications of wireless sensor networks (WSNs) field. A localization algorithm based on improved Support Vector Machine (SVM) for WSNs is proposed in this paper. SVM classification accuracy is the key to the localization accuracy. The selection of parameters is the important factor that influences the performance of SVM. Therefore, this paper proposes a parameter optimization algorithm based on Krill-herd algorithm (KH-SVM). The experimental results show that KH-SVM algorithm has better searching optimization ability compared with other optimization algorithms. In order to improve the fault tolerance against both random attacks and deliberate attacks for wireless sensor networks, this paper proposes a evolution model.We present an efficient seismic data sensing scheme in wireless sensor networks based on the promising compressed sensing technology to mitigate wireless communication load, data processing and caching complexity on nodes.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86327834","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}

Competitive Intelligence (CI) is important for companies to manage their information. CI identifies opportunities and determinants of success, anticipates threats and prevents risks. CI becomes an imperative for any company wishing to sustain its growth and innovation sustainably. In addition, decision-makers have a key role to play when making decisions, some of which can have a significant impact and therefore justify the effort to reflect and deliberate on possible options before making a decision. Strategic decisions can be defined as important and far-reaching decisions in terms of actions taken, resources committed, number of actors involved and impact on all future operations. Our answer to this challenge is an approach that uses Rough set theory. Our approach is designed to support decisionmaking and respects the characteristics of strategic decision support in complex, uncertain and evolving situations. Rough set theory can effectively process data and information in complex system. In this article, we propose a CI approach where we used the rough set theory to generate rules in order to help decision makers make a decision in a complex and multi-criteria situation and under a context of uncertainty. We applied our model on the choice of implementation of an Enterprise Resource Planning (ERP) within the company.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88602422","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}

Secondly, the image captured by the camera is processed by taking the five-frame difference methodto extract the identification target from the pre-processed images and the HOG feature of the identification target is extracted as the input of the classifier to identify the target.

An insertion of a new item causes a failure and an endless loop when there are collisions in all probed positions till achieving the timeout status. To interrupt the countless loops, an intuitive manner is to carry out a complete rehash if this uncommon incident takes place. In practice, the high priced overhead of acting a rehashing operation can be dramatically decreased by using taking benefit of a very small extra regular-size space. In our proposed paper hashing involve collisions in which the stored buckets with one item will be reduced to probe the hash collision and query about the buckets. The enumerator that allocates each hash bucket will reduce the endless loops. As an accession we include intrusion detection and defense implementation (IDDI) that scrutinizes the hash and cache memory utilization efficiently. Cuckoo hashing is more prone to intrusion attack for which we alleviate such attacks by avoiding loops in buckets. Through detection and avoidance mechanism of intrusion we enhance the transmission in cuckoo hashing simultaneously by providing strong security towards its data.","PeriodicalId":91890,"journal":{"name":"IOSR journal of computer engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80754528","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}
