The next generation of DVB-based GEO satellites, supporting real-time multicast services, is characterized by the OBS (On-Board Switching) and multiple spot beams technologies. In this paper we focus on the efficient transmission of IP multicast over satellite DVB and on its security. For this, we propose a new encapsulation method called Enhanced ULE, derived from the ULE (Unidirectional Lightweight Encapsulation) standard encapsulation method. Our proposed encapsulation scheme adds zero overhead to ensure good link efficiency and preserve the expensive satellite resources. The EULE can get easily adapted to the existing OBS approaches, namely the label-switching and the self-switching, in order to ensure an efficient filtering and multicast forwarding. Since the security of multicast transmission is an important concern for operators to protect against eavesdropping, we also propose a secure version of the EULE called SEULE which provides all security services. The analysis of the proposed SEULE with the two switching approaches is presented, simulated and discussed.","PeriodicalId":180400,"journal":{"name":"2012 Symposium on Broadband Networks and Fast Internet (RELABIRA)","volume":"78 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115582882","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 key idea to solve the problem of the mixed priority strategy is the technique of the Shadow server approximation. Specifically, we present a single-cell WiMAX environment in which the base station allocates subchannels to the subscriber stations in its coverage area. The subchannels allocated to a subscriber station are shared by multiple connections at that subscriber station. To ensure the Quality of Service (QoS) performances, two Connection Admission Control (CAC) mechanisms, namely, threshold-based (tb) and queue-aware (qa) CAC schemes are considered at a subscriber station. Then, based on the queueing model, both the connection-level and the packet-level performances are studied and compared with their analogues in the case without CAC. The connection arrival is modeled by a Poisson process and the packet arrival for a connection by a Markov Modulated Poisson Process (MMPP). Several performance measures are derived.","PeriodicalId":180400,"journal":{"name":"2012 Symposium on Broadband Networks and Fast Internet (RELABIRA)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115886673","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}

Recently, many solutions were proposed in the literature to reduce the power in cellular communications while maintaining the quality of service, in the purpose of achieving, what is known now as “Green Communications”. In this paper, we are interested in power-efficient methods altering the transmitted power of base stations, especially Sleep Mode and Cell Zooming techniques. After presenting the advantages, drawbacks and implementations of these two green solutions, we will introduce a new algorithm that should be implemented and applied on the base stations to reduce their total power consumption. This algorithm considers several cases including Cell Zooming and combination of Sleep Mode and Cell Zooming depending on the cell loads and mobile distribution. It also computes the power needed in each case and then chooses the most power-efficient scenario. Moreover, we will study the performance and efficacy of implementing our algorithm in some practical cellular network settings.","PeriodicalId":180400,"journal":{"name":"2012 Symposium on Broadband Networks and Fast Internet (RELABIRA)","volume":"65 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-05-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132531954","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}
