The Coordinated Multipoint (CoMP) technology adopted in long-term evolution (LTE) cellular networks allows improving the cell's edge performance. In order to improve throughput performance gain in the downlink, the CoMP scheduler needs to know/deal the channel information for all the collaborating Base Stations. To do so, we propose a method for handling Channel State Information (CSI) feedback, named DCEC: Direct CSI feedback to Elected Coordination station. The DCEC architecture aims to reduce the overhead and latency of the network, and subsequently increase its throughput. To model the proposed architecture in the cellular network, we have used the Discrete Event System Specification (DEVS) formalism. The simulation results demonstrate that the DCEC architecture significantly decreases the number of CSI feedback packets being transmitted within the network and reduces the feedback latency resulting in higher data rates for users.","PeriodicalId":302558,"journal":{"name":"2016 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125833560","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 concern goes hand in hand with demand for higher bandwidth which leads to need to develop new compression standards as VP9 or H.265/HEVC. This results in requirements for video quality assessment as one main part of the multimedia stream. Compression together with transmission link imperfection are two major factors that influence the quality. This paper deals with assessment of impact of VP9 compression standard on the video quality using different subjective metrics. The evaluation is done for two types of sequences with Full HD resolution depending on content. The main outcome obtained from the results is the determination of the threshold in the means of point where the quality do not rise so swift. This threshold was set between 5 and 7 Mbps. After this threshold the observers did not evaluate the quality of both sequence with quite higher marks which means there is no need to compress the sequences to higher bitrates than to 7 Mbps. These results are part of a new model that is still being created and will be used for predicting the video quality in networks based on IP.","PeriodicalId":302558,"journal":{"name":"2016 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127096966","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 service takes as input a userprovided network system model and delivers as output an ns-3 'main' program. An accompanying user-based modeling tool provides a graphical user interface for constructing and editing models of four layer Internet systems in terms of backbone nodes and links, different types of wireless networks (LTE, Wifi infrastructure, Wifi adhoc, Wimax, or CSMA), end-to-end application traffic sources, mobility models, routing protocols, and trace sources. Methods are also developed to make the cloudbased program generation service secure in terms of not exposing network model information in the cloud during the entirety of the program generation process. A masking technique is presented for hiding network information such as node or link names, link end-point names, IP and MAC addresses, model option choices, parameter values, and application-layer traffic end-point names. A network model decomposition technique is presented for obscuring network topology information such as the mix and graphical interconnection of nodes, links, wireless networks, wireless network elements, and application-layer traffic flows. The ns-3 program generation service facilitates the production and editing of ns-3 programs for large or complex network systems. It can also assist new users or non-experts with generating ns-3 programs.","PeriodicalId":302558,"journal":{"name":"2016 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114164372","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 research comprises the automatic management of three main approaches, being firstly the deployment of a virtual infrastructure for experimentation, secondly the configuration of the detection and mitigation of DDoS attacks and finally the analytical tools to corroborate with introduced countermeasures. In order to accomplish these purposes, we have designed and constructed an experimental topology based on virtual networks, which injects and mitigates DDoS attacks. Simultaneously, we designed and developed a software application to manage automatically the deployment of the experimental topology and the configuration of the detection and mitigation of DDoS attacks. To guarantee the reliability of the outcome, we configured a rule-based detection mechanism for Linux through the optimization of an algorithm that resolves anomalies in firewalls rules. The results demonstrate quantitatively the efficiency of this proposal.","PeriodicalId":302558,"journal":{"name":"2016 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127899214","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}

When people encounter each other, their handheld devices can communicate wirelessly and in a cooperative way using the encounter opportunities for forwarding their messages. However, in the real world, most of the nodes exhibit selfish behaviors mostly to conserve the limited buffer and power resources. As such, for ensuring a fair delivery, node selfishness should be taken into account. In this paper, we study the impact of node selfishness on the system throughput and delay of opportunistic communications. Through extensive simulations, we evaluate the system performances by utilizing experimental human mobility traces with different communication patterns. Our results show that the message delivery ratio decreases and the end-to-end average latency increases as the percentage of selfish nodes increases for all the routing protocols considered. However, the social-based forwarding rules are able to better manage node selfishness.","PeriodicalId":302558,"journal":{"name":"2016 International Symposium on Performance Evaluation of Computer and Telecommunication Systems (SPECTS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115534351","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}
