Context awareness can play a major role to improve mobile networking systems and to ensure seamless mobility. In this paper, we focus on Vertical Handover (VHO) decision optimization within heterogeneous wireless environments, where users may connect to different wireless access networks simultaneously (e.g. 2.5G, 3G, WiFi, WiMax). We propose a Reputation based Vertical Handover Decision making Framework (R-VHDF) where the decision is not only based on the Received Signal Strength (RSS), as in most horizontal handover processes, but also on context information about QoS and radio conditions, as well as on networks and previous user's experiences (QoE or Reputation). The solution is based on a flexible and evolutionary distributed context management architecture that handles dynamic and static context information and allows mobile devices to be always connected to the most suitable access network by making VHO decisions based on networks' Reputations. The proposed framework encompasses auto-programmable platforms and distributed context management components within middleware servers and mobile devices. It is validated thought a prototype implementation and performance results are presented and discussed.","PeriodicalId":290330,"journal":{"name":"2012 IEEE Globecom Workshops","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133868096","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}

As more and more applications are encrypting the payloads and not to use well-known ports, traditional traffic classification methods such as transport-layer protocol ports based ones can not accurately and efficiently deal with these applications. In this paper we investigate the problem of classifing traffic flows into different application categories. And a new bag-of-words (BoW) model based traffic classification method is proposed, which has been widely used in document classification and computer vision. In the new traffic classification method the application categories of interests represents the bags, centroids represent the words of the BoW model, respectively. By constructing representation vectors for the application categories and calculating the cosine similarity between each category representation vector and newly built-up vector converted from flows to be tested, we can find the application category that a tested flow belongs to. Using real traffic traces we demonstrate that the proposed approach is able to achieve 93% overall accuracy and the classification is not affected by the packet arrival sequences (e.g. out of order arrivals). The overall accuracy of the proposed approach is observed to be higher than the widely used C4.5 algorithm by 10% in our experiment when the out of order arrival happens.","PeriodicalId":290330,"journal":{"name":"2012 IEEE Globecom Workshops","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124636894","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 core problem of the area is virtual network embedding, which is centering on how to efficiently map the virtual requests to the substrate network. In order to reduce the computational complexity, previous researches mainly devise heuristic algorithm and divide the whole process into node mapping and link mapping. But most of them consider separately node mapping and link mapping, which may lead to poor performance of the whole algorithm because of the unreasonable node mapping. In this paper, a new algorithm is proposed based on the minimum node stress and adjacent principle. During the period of node mapping, the node stress is kept balanced. Meanwhile, using the adjacent principle, the link stress can be reduced to a low level. Thus, the possibility of bottleneck node is reduced and the resource of substrate network can be efficiently used. The simulation demonstrates that the new algorithm reduces the maximum node stress and link stress of the substrate network, and makes it load balance.","PeriodicalId":290330,"journal":{"name":"2012 IEEE Globecom Workshops","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134313928","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}
