In this paper, when physical faults occurred in the NFV Framework, or logical failure occurs on a specific logical device, we will present a structure for Fault Localization method to ensure the continuity of service in NFVI.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"219 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122935677","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 coverage and capacity deployment strategy has also been combined to clarify the optimal implementation based on financial constraints.

Due to the unmanageability characteristics of P2P networking, it tends to lead to inefficiency due to ignorance of underlying network in spite of its advantages and unfairness caused by absence of incentives to contributing peers. In order to solve several issues regarding P2P networking and making use of its advantages compared to existing server-client model, ITU-T Q.9/11 is developing a series of MP2P (Managed P2P communications) standards. In order to figure out the status of overlay network and gathering activities information of peers, it aggregates the information from peers that may not be trusted due to the possibility of forgery. It is important to assure the integrity and non-forgery of reports from peers. In this paper, we propose a method for gathering reliable peer activity report by use of digital signatures.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128341243","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}

Among them Spark has become increasingly popular big data processing framework since it was presented in 2010 first time. Spark use RDD for its data abstraction, targeting at the multiple iteration large-scale data processing with reuse of data, the in-memory feature of RDD make Spark faster than many other non-in-memory big data processing platform. However in-memory feature also bring the volatile problem, a failure or a missing RDD will cause Spark to recompute all the missing RDD on the lineage. And a long lineage will also increasing the time cost and memory usage of Driver analysing the lineage. A checkpoint will cut off the lineage and save the data which is required in the coming computing, the frequency to make a checkpoint and the RDDs which are selected to save will significantly influence the performance. In this paper, we are presenting an automatic checkpoint algorithm on Spark to help solve the long lineage problem with less influence on the performance. The automatic checkpoint will select the necessary RDD to save and bring an acceptable overhead and improve the time performance for multiple iteration.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124534624","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}

Throughput at MAC layer is calculated from transmission probability, contention window and transmission stage. Likewise, the new critical attributes of 802.11ac PHY (i.e. modulation and coding schemes, spatial streams, and channel bandwidth) are used to determine the throughput. To this end, a theoretical model is developed followed by simulation analysis. The results compare theoretical and simulation findings for different set of parameters. Furthermore, important trends and tradeoffs are identified between system throughput and (MAC + PHY) features as a function of number of contending stations and payload size.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133438186","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 order that devices directly communicate, they must first find and identify each other. Especially, in a disaster environment where wireless channel conditions may be very poor, discovery should be robust and fast for quick resume of the blocked communications again. In this paper, considering frequency selective fading which may lead to missing devices even though they exist, we propose a device discovery scheme using a simple physical layer waveform called signature. Typically, in a signature-based discovery under OFDMA-based system, a device advertises its presence by selecting a discovery channel and energizing subcarriers in the channel for a while (one subcarrier at a time). In the proposed scheme, we design discovery channels having well dispersed subcarriers to tolerate the frequency selectivity. By simulation, it is shown that not only successful discovery ratio of the proposed scheme is improved, but also our scheme is more frequency selective fading tolerant in comparison with other approaches.","PeriodicalId":125854,"journal":{"name":"2016 18th International Conference on Advanced Communication Technology (ICACT)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130173461","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}
