Tremendous efforts have focused on the interference management (IM) for HetNet. Nevertheless, for different network configurations' e.g., different deployments of small cell (SC) base stations (BSs) and users, different number of SC BSs and users, etc., the performances of different IM schemes may vary. The current fixed only one or two types of IM schemes can not guarantee the optimal performance for different scenarios of mMIMO HetNet. Therefore, a hybrid IM schemes is proposed here. We formulate the determination of IM schemes as an optimization problem for maximizing the overall data rate, which is solved by the D.C. (difference of two convex functions) program. Numerical results show the significant performance enhancement compared with the fixed IM schemes. Moreover, it is found that, for large coverage of SC case, nearly maximum system performance in practical scenario can be achieved with not so large number of antennas at macro-cell BS.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130916010","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 the ability of the controller to communicate with switches is critical for the operationability of the network, reliable connectivity of the control channel must be provided. This question is especially important for in-band control channels, where no separate management network is available and most switches are not directly connected to the controller(s). In our previous work [1], we argued for providing reliable connectivity for the in-band control channel using a distributed routing protocol. We presented the protocol Izzy which is optimized for robust connectivity between a single SDN controller and the switches under its control. Realistic deployments, however, use logically-centralized controller clusters for reliability and scalability reasons. In this paper, we describe how to extend Izzy to support such logically-centralized clusters. We propose to divide controllers into groups based on distance between them. Each such group runs a separate instance of Izzy. This paper presents the distributed algorithm Seedling that accomplishes the former. We describe how Seedling works in static scenarios followed by an outline of necessary steps to extend it to dynamic settings including changes to both the number and location of controllers as well as to network topology, especially link failures.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125388609","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}

Thus, access control in Health Informatics needs be highly efficient and scalable, while remaining flexible enough to adequately address the heterogeneous security requirements. Among the most promising work on access control is CBAC. However, all prior work employed asymmetric cryptography to sign capability tokens, which prevents its use on the most constrained devices. Previously we proposed the Lightweight Capability Based Access Control (LCap) [1] that overcomes this restriction by using symmetric cryptography. In this paper, we discuss the limitations of LCap and propose modifications to overcome them. Our evaluation of the enhanced LCap shows, that its impact on response time is insignificant and its computational overhead is moderate. This allows the deployment of LCap even for the most constrained devices in Health Informatics.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"28 9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125693637","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}

Offloading in HetNets alleviates congestion on the overloaded cellular network where the femto base stations (FBS) acts as offloading spots. The offloaded user (OU) is paired with the user available at the FBS (called as pairing user (PU)) and served using non-orthogonal multiple access. Two parameters namely, power allocation factor (PAF), i.e., the power to be allocated to the OU, and channel ratio (CHR), i.e., the ratio of channel gain between the OU and the PU play a crucial role in determining the ergodic rate achieved by the OU. If the PAF and the CHR are not optimally selected, it results in degradation in overall rate performance. This work jointly optimizes the PAF and the CHR to maximize the ergodic rate performance of the OU. The impact of optimized and non-optimized parameters on the performance of OU is studied to prove the advantage of using optimized scenario for the OU. An increase of upto 3 times is observed in the ergodic rate and sum ergodic rate by using the optimized parameters.","PeriodicalId":348924,"journal":{"name":"2018 IEEE Globecom Workshops (GC Wkshps)","volume":"88 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122652665","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}
