The application of wireless video has become an indispensable part of daily life. Conventional wireless video transmission systems do not accommodate the broadcasting scenarios because of the variety of channel conditions with different terminals. Recently, a joint source-channel coding scheme named SoftCast which can provide graceful degradation has been presented. But the protection for important data is not accuracy enough due to the lossy transmission. Besides, the whitening operation does not have enough flexibility which is caused by Hadamard matrix. In this paper, we propose a new adaptive wireless video coding scheme which uses quadtree partition method to achieve whitening operation. Compared with Hadamard transform, the quadtree partition method has more flexibility. Moreover, we use an adaptive module to resist the channel noise and provide more protection to important data which exist in low-frequency subband. The experimental results show that our proposed scheme is about 3–5dB better than SoftCast in reconstruction quality. And the capability of resistant to random packet loss is comparable with Hadamard transform.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"19 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":"132955296","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}

DPRP with a user voting method rather than Dynamic Point Blanking (DPB) is introduced to fully use the power while reducing energy consumption and mitigating inter-cell interference. The pattern of reducing power is decided in a user-centric way. Firstly, CoMP user equipments (CUEs) report to two base stations (BSs) to inform their urgency of CUEs to reduce power. Then the BSs reduce power on some resource blocks (RBs) which affect most UEs so as to get EE improved. JT with overlapping cooperation set is applied only to the CUEs to improve their throughput, therefore not bringing too much pressure to backhaul. The cooperation set of JT is decided by CUEs instead of the location of BSs to better adapt to the requirement of CUEs. Simulation results show that the scheme we proposed can improve EE obviously without leading to too much drop in user throughput.","PeriodicalId":439987,"journal":{"name":"2016 IEEE International Conference on Network Infrastructure and Digital Content (IC-NIDC)","volume":"42 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":"133948795","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}

When the same intensity of threats occurs at different physical locations, the damage to the network performance varies greatly. In the network vulnerability assessment, the critical region is defined as the destructed area which would lead to the highest network disruption. Traditional critical region identification for network vulnerability assessment is only determined by nodes, without considering the failures of the links. To this end, this paper proposes a critical region identification method that joints nodes and links to find the critical region. We study this vulnerability assessment problem in two cases, the special case of the failure center constrained at a network node and the general one of that at an arbitrary location, and propose two algorithms for these two cases respectively. The simulation-based experiment on synthetic network is given with different criticality metrics. The simulation results verify the feasibility and effectiveness of our proposed critical region identification method in comparison to others.","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":"128536711","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}
