In any situation where there are a certain number of secondary networks trying to get an available channel, there arises a game theoretic competition where they want to get the channel for themselves by incurring as minimum cost as possible. The increase in cost is equivalent to the increase in time caused by the need of a search for an available channel. This process could be sped up if the networks had a predictive mechanism to determine the optimal strategy. In this paper, we investigate various predictive algorithms: Linear regression, Support Vector Regression and Elastic Net and compare them with other traditional non-predictive game theoretic mechanisms. We measure the accuracy of these algorithms in terms of time taken to reach the system convergence. We also observe how a self-learning approach can be helpful in maximizing utilities of the players in comparison to traditional game theoretic approaches.","PeriodicalId":224620,"journal":{"name":"2017 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"94 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130832964","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}

We present an online analytical processing (OLAP) system for early alerts of upcoming malicious activities. This study aims to systematize the support of cybersecurity granted by a Computer Security Incident Response Team (CSIRT) and shall help to establish a mechanism to analyze and improve the overall level of security of networks and equipment by providing early warning services. In order to accomplish this task, a Business Intelligence solution has been developed adapting the methodology of Ralph Kimball to support the analysis of computer security incidents. This generates a data warehouse of information collected from alerts and events recorded from a continuous transmission of data from various Internet security sources that gather, trace and report malware, botnet, and electronic fraud. Furthermore, we constructed with Pentaho BI load data into the dimensions, measures and facts, OLAP cubes, reports and dashboards. The acquired results demonstrate the functionality of the application where it is possible to visualize with certainty of both, the early warnings, as well as the level of security of the participant Institutions, about the registered threats and vulnerabilities.","PeriodicalId":224620,"journal":{"name":"2017 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"32 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114105312","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 aim is to provide inspiring insights in this domain from a technological and computational point of view. In these last years, indeed, there is an enormous potential that UAV technologies presents to support the agricultural domain in monitoring the land for checking and countering the presence of parasites that can damage the crop. However, to properly manage a UAVs team, equipped with multiple sensors and actuators, it is necessary to test these technologies and design proper strategies and coordination techniques able to efficiently manage the team. At this purpose, the paper proposes a simulator suitable for the agriculture domain in order to design novel coordination and control techniques of a UAVs team. Moreover it is possible to define the main variables and parameters of this domain of interest. The work presented many coordination techniques both for monitoring the area and both for coordinating the actions of the drones in the presence of parasites in order to analyze how the performance can significantly change if more constraints, such as energy, communication range, resource capacities, are accounted.","PeriodicalId":224620,"journal":{"name":"2017 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134402990","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}

CYBersecurity information EXchange (CYBEX) is playing a crucial role to implement proactive defense. CYBEX conveys organizations' sensitive information which demands proper access control management. However, previous works in this area do not consider access control for CYBEX. In this work, we tackle the access control problem in CYBEX. We model the attribute based access control in CYBEX with a semi-trusted sharing server. To achieve attribute based access control in CYBEX, our mechanism is developed based on the concepts of ciphertext policy attribute based encryption (CP-ABE) [1] and STIX [2]. The mechanism's workflow is as follows, at the beginning users claim their attributes from attribute authorities, then a key generation center generates decryption keys for users based on their attributes. For the sharing, organizations embed access control to their shared data. This is conducted by encrypting sensitive information such that only users with appropriate attributes can decrypt them. Security analysis, implementation and performance evaluation indicate the effectiveness and efficiency of the mechanism.","PeriodicalId":224620,"journal":{"name":"2017 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131090512","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 throughput test using the UE's FTP application to perform the throughput test has a merit of presenting the packet data speed from the end user perspective however, it also has significant shortcomings such as multiple RF layers cannot be tested simultaneously as UE can have only a single radio connection to eNB and no analytic performance benchmarking between different LTE networks is possible. The proposed algorithm utilizes the simple measurement quantities collected by an RF scanner in order to estimate the LTE network's traffic load and the available PRBs without relying on network parameters or site information. Furthermore, the proposed algorithm calculates the potential downlink throughput at each location at which the RF scanner measured RSRP, RSRQ and SINR assuming that the available PRBs of the LTE cell are fully utilized at the location. Since the RF scanner is capable of measuring the multiple RF layers simultaneously, the proposed algorithm enables whole LTE networks to be benchmarked comprehensively. In addition, the proposed algorithm helps in analytically determining the root causes of the superiority or inferiority of a LTE network whether it is due to traffic load, system bandwidth, or spectrum efficiency.","PeriodicalId":224620,"journal":{"name":"2017 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124934302","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}
