And many rate adaptation algorithms have been proposed to decide the best bitrate for DASH video players. In different real applications, not all the video segments are of same importance for users. However, none of these existing rate adaptation algorithms takes segment importance into consideration. In this paper, we propose a segment importance based rate adaptation (SIA) algorithm for DASH, which not only considers the network bandwidth and the client video buffer but also takes segment importance into account. To evaluate the performance of SIA under different bandwidth conditions, experiments are conducted under both different values of fixed bandwidth and available bandwidth variations. And results show that SIA achieves a considerable gain for the average bitrate for important segments (ABIS) under low fixed bandwidth and available bandwidth variations while keeping comparable performance of other objective QoE metrics compared to the buffer-based rate adaptation (BBA) [6] and the segment-aware rate adaptation (SARA) algorithm [11]. We also validate that in a certain range, the increment of the percentage of important segments in SIA will lead to the decrement of ABIS and the increment of the duration of video rebuffering.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129668771","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, C-RAN demands a comprehensive evaluation model and accurate qualitative metrics for designing Base Band Unit (BBU) and Remote Radio Head (RRH) switching mechanism. Many literatures have studied an energy consumption model which discusses the optimized resource utilization and power saving compared with typical RAN architecture, but it seems that they did not consider how to guarantee the quality of service (QoS) that may require more limitation. This paper is the first to study the C-RAN to achieve the reasonable BBU-RRH switching with good QoS by considering two new factors, resource waste (ReW) and traffic backlog (TB), which directly affect system performance. New BBU-RRH switching model for C-RAN is proposed for finding out the loss indicated by ReW and TB. An algorithm that optimizes the QoS, resource utilization and power saving of system is derived and it contains two parameters called higher threshold (HT) and lower threshold (LT) that represent upper limit and lower limit of one BBU's resource utilization, respectively. And we provide a parameter Pu as the evaluation criteria for HT and LT. Numerical results validated theoretical analyses and revealed HT set to 0.85 and LT set to 0.35 as optimal configuration under the assumptions in this paper. Compared with existing literatures, this paper solves the calibration of HT and LT for C-RAN BBU-RRH switching schemes.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121313671","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}

There are lots of baseband units (BBU) in C-RAN. All BBUs are in active mode even when traffic load is light, this brings the problem of high energy consumption in BBU Pool. BBU switching scheme can switch off part of BBUs to save energy. It needs to consider BBUs' resource utilization rate but estimating BBUs' resource utilization rate is a challenging issue and lacks researches. In this paper, firstly we propose a novel scheme to estimate BBUs' resource utilization rate with the consideration of rate requirement of mobile user equipment (MUE), number of MUEs, bandwidth of Remote Radio Head (RRH) and the transmission power between RRH and MUE. Secondly, we provide a combine and remove (CnR) algorithm to decide BBU when to be switched off or to be switched on. It can remove overloaded BBU and underloaded BBU while combine them together and transfer them to normal BBU or sleeping BBU. The algorithm aims to maximize the number of sleeping BBUs without losing of Quality of Service (QoS). Numerical results indicate that the number of sleeping BBUs reaches maximum, BBUs' resource utilization rate keep in normal state and the energy consumption in the BBU Pool varies with the fluctuation of traffic load. In addition, our proposed scheme outperform the primary static scheme and schemes in relevant papers in terms of energy saving in the BBU Pool. The overall system using our scheme also consume less energy compare to the traditional RAN according to the provided energy consumption models.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130747955","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}
