The inherent centralized nature of the SDN controller brings sufficient flexibility to network management, but in the case of congestion episodes or failure, the whole system can be affected. In that respect, the spatiotemporal variation of the network traffic affects the network performance by increasing the response time of the control plane when it is overloaded, raising in that respect the issues of reliability and scalability. In this work, we are aiming to tackle the problem of load balancing in the control plane. The proposed approach aims to balance the load among multiple controllers by assigning switches to controllers. By considering both reactive and proactive assignment in a multi-controller setting, two costs are studied. The bi- objective function is composed of the cost of load balancing within controllers and the cost of traffic load migration. The problem of controller assignment is formulated as a Quadratic Programming, constrained by computing resources. Finally, to overcome the curse of dimensionality due to the increasing number of variables, a min-max model is presented as a mixed-integer linear programming problem minimizing the maximum load of controllers. Simulation results shed light on the trade-off between load balancing and migration cost, and the performance evaluation is demonstrating the efficiency of the proposed model compared to previously proposed algorithms in the literature.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":"44 10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125675149","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, the face structures is inherently missing due to the degradations in the imaging process, leading to the severe interference in the face enhancement and subsequent face recognition procedure. To remove the degradations and recover a recognizable face, we propose a novel global facial context prior as the guidance to face super-resolution problem. The global facial context prior expands the local structure prior, which is represented as the local patches, into global-face range by modeling the whole facial patch positions into network scheme empirically according to position distributions. The local structure in neighbored positions provides better guidance for reconstruction than the local structure itself, especially when the size of local distortion is larger than the local patch size in input image, leading to the fact that the local input image patch unable to give informative details. Therefore, the global facial context prior improves the robustness of algorithm in dealing with large-range uneven image distortion, e.g. the occlusion. The quantitative and qualitative evaluation on public database demonstrates the superiority of our algorithm.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121364897","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}

In this paper, we investigate the potential of local collaboration among vehicles to mitigate the load on V2N (e.g., cellular) communication networks. Vehicles in the vicinity use vehicle-to-vehicle (V2V) communications to form a group, called vehicular micro cloud, and each of them downloads a subset of data segments that comprise an original data content. The downloaded data segments are cached and shared with other group members by way of V2V networks. This enables the group of vehicles to collectively serve as a virtual content delivery server, which complements cloud / edge computing infrastructure. In order to maximize the benefit of cooperation, we design a light-weight local coordination mechanism for vehicles to agree on non-overlapping subsets of data segments that they request from a remote server. Our simulation results show that coordination among vehicles improves the efficiency of cooperative download, reducing the data traffic on cellular networks.","PeriodicalId":210825,"journal":{"name":"2019 IEEE Globecom Workshops (GC Wkshps)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128926322","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}
