The performance of the considered HSTRN may be critically affected by outdated channel state information (CSI) and CCI in practical operating environments. Leveraging the statistical characterizations of the underlying hybrid channels, we first derive a novel closed-form expression of outage probability of the considered system. Then, we derive an asymptotic outage expression to examine the achievable diversity order. Numerical and simulation results corroborate the analysis and illustrate the impact of outdated CSI and CCI on the HSTRN performance.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130714510","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}

However, because of the rapid increase in data link speeds and the volume of traffic carried by modern networks, the availability of system resources dedicated to network measurement has always been the main limiting factor in developing modern measurement solutions. The emergence of Software Defined Networks in recent years has inspired the development of new measurement solutions that takes advantage of the capabilities offered by this new paradigm such as programmability and central management [9]. Current SDN enabled measurement solutions are able to orchestrate the execution and resources allocation of network-wide measurement tasks but still falls short in their ability to recognize efficient operating points (amount of allocated resources) for running tasks and often results in inefficient resources utilization. In this paper we provide a novel resource allocation method that continuously estimates the resources-accuracy relationships for running tasks, infers their individual points of diminishing-returns and uses the resulting value of each task as it's target point of operation in order to achieve a more efficient resource utilization. In contrast to existing work, our proposed method maximizes the return on used system resources and results in lower drop rates of running tasks as shown by our simulations.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122589924","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}

They were initially designed to serve a number of subscribed User Equipments within their range. This design however, resulted in underutilization of the femtocells resources, and simultaneously in high interference levels for nearby non-subscribed users. Nowadays, femtocells can support multicast transmissions, while their hybrid operation allows non-subscribed users to use a portion of their resources. In this paper we propose a novel mechanism that is based on the selection of the appropriate Modulation and Coding Scheme. The mechanism allows non-subscribed users to utilize a portion of the femtocells' resources for multicast transmissions when located inside their coverage, without affecting the owners' satisfaction. The simulation results show that depending on the portion of the femtocells' resources allocated to non-subscribed users, the mechanism may significantly increase the average user throughput.","PeriodicalId":416277,"journal":{"name":"2016 European Conference on Networks and Communications (EuCNC)","volume":"122 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123113096","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}
