In this view an intelligent distributed architecture that enables dynamic user management and control on network-wide resource sharing by using the Service Oriented Architecture concept is presented.

Our analysis is basing on a numerical evaluation, taking into account major cost drivers for CapEx and OpEx. Furthermore the impact of different FTTH service penetration scenarios is investigated. This article is organized as follows: Chapter II introduces some basic design principles of optical access networks followed by a brief qualitative comparison of flexible and fixed ODN design.

While several approaches are available that propose different approaches, still the problem of reasoning represents a challenging issue.

In particular, the idea is to provide a methodology to enable network nodes to represent the complex interactions that happen within their protocol stacks and across the network. The potential utility of the proposed scheme is then preliminarily validated on a sample scenario, outlining good results and relevant potential for future developments.

It naturally applies in many applications in Vehicular Ad-Hoc Networks, where useful information needs to be made available to all vehicles within a confined geographical area for a specific time interval. A straightforward approach, is to have all vehicles within the hovering area exchange messages with each other. However, this method does not guarantee that all vehicles within the hovering area will receive the message due to potential parti- tioning of the network in areas with low traffic density and/or low market penetration rate. In this work, we address the problem by applying probabilistic flooding schemes outside the hovering area. Informed vehicles outside the hovering area can serve as information bridges towards partitioned uninformed areas thus leading to high reachability. We consider a number of rebroadcast probability functions and we evaluate their performance using the microscopic simulation tool VISSIM. Our reference model represents a section of the road network in the cities of Bellevue and Redmond in Washington. The obtained results indicate that probabilistic flooding with a Gaussian like probability function outperforms other approaches by achieving high reachability values and a relatively small number of exchanged messages.","PeriodicalId":115189,"journal":{"name":"2009 IEEE Globecom Workshops","volume":"55 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115531362","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 performance of WMNs depends on the joint effect of both routing algorithms and rate adaptive algorithms. The performance of various routing algorithms has been studied extensively in the literature. However, little work has been done to evaluate the cross-layer impact of rate adaptive algorithms in WMN environments. In this paper, we compare the performance of several rate adaptive algorithms to exploit the multi-hop performance in WMN environments. In addition, a novel rate adaptive algorithm is proposed via the machine learning approach to robustly reflect the channel information. The goal of our design is to maximize the spectral efficiency. Through extensive computer simulations under different channel and topology environments, experimental results demonstrate the proposed algorithm outperforms other existing algorithms in WMN environments.","PeriodicalId":115189,"journal":{"name":"2009 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122766063","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}

Furthermore, the process of dealing with aspects of \"Socio-economic Management\" is discussed, which determines a hybrid and innovative approach besides traditional network management approaches. This determines a network management in which control is delegated via socio-economic means and to a certain extent to the user and provider with the goal to maximize the overall social welfare and the networks technical efficiency at the same time. This is refined by a set of SE-driven management mechanisms, the discussion of abstract user/network interfaces (stakeholder relations), and an example case for managing overlay traffic in such a network management system. Finally, based on a set of ideal SE requirements derived from the analysis of existing approaches, a set of preliminary conclusions is drawn.","PeriodicalId":115189,"journal":{"name":"2009 IEEE Globecom Workshops","volume":"134 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116724942","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 concept of cognitive radio is also exploited in the railway context in order to satisfy high availability and interoperability of wireless telecommunication systems everywhere as required by operational or safety applications deployed by the railway operator. It allows for example dynamic spectrum allocation versus QoS (Quality of service) or traffic requirements and very often spectrum reuse especially in rural areas. Blind multi-carrier transmission recognition methods based on the discrimination between single-carrier and multi-carrier modulations to estimate their parameters have been addressed in the literature. Some powerful techniques use autocorrelation and cyclic autocorrelation based features of the transmitted signal. In this paper, we propose a blind parameter estimation based on analysis of fluctuations of autocorrelation estimators which was initially employed in CDMA signals interception. The proposed technique leads to a fast efficient parameters estimation and is insensitive to receiver phase and frequency offsets as it is highlighted in simulation results.","PeriodicalId":115189,"journal":{"name":"2009 IEEE Globecom Workshops","volume":"120 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126801511","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}
