The radio spectrum condition is greatly affected by the buildings and there will be many communication dead zones in the metropolitan area environment if only macro cells are deployed. Generally, the communication dead zone is always small and in irregular shape, therefore, the deployment of small cells is one of the most convincible ways to deal with it. However, the interference, necessary overlapping for handoff, coverage improvement, and cost are correlated to one another. And it is hard to determine the number and locations of small cells to be deployed. In this paper, we propose the Particle Swarm Optimization (PSO) based small cell placement algorithm to effectively deploy the small cells in the communication dead zone of metropolitan area. The fitness value in the PSO process of the proposed scheme is tuned by the adaption function to compromise the coverage maximization and necessary overlapping of small cells. A practical area of Taipei City was adopted as an experimental example to investigate the performance of the proposed scheme. The experimental results illustrate that the proposed scheme places small cells in proper locations so that the coverage can be effectively improved.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130570937","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}

OpenFlow is the popular SDN de-facto standard, which has been prevalently adopted by both academia and industry for research and development purpose. OpenFlow provides rich programmable interface to network administrator to ease traffic monitoring and control. Because OpenFlow supports L4 network stack, it is feasible to provide application level traffic control by specifying TCP/UDP port number in flow rules. The major deficiency of the port-based traffic control is that it only provides the ability to control traffic from applications which have well-known TCP/UDP port numbers. In the case of port number change or dynamic (ephemeral) port allocation to an application, it is difficult to accurately control the application traffic. To be a solution, we propose an application-aware traffic management method by integrating Deep Packet Inspection (DPI) function with SDN controller. To show the feasibility, we design and implement Firewall and Bandwidth Manager applications based on the proposed management method. The applications perform on top of ONOS [1] controller, and FTP rate control example is shown to prove the feasibility of the proposed flow management method.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"33 3","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133203661","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}

With virtualization, resource utilization is higher, system performance is improved and the investment capital is lower. However, there are remaining challenges to be addressed before wireless virtualization is widespread deployed. One challenge is user association which has great influence on the performance of the wireless virtualization network. Traditionally, user associates to the base station (BS) who provides the highest signal to interference plus noise ratio (max-SINR). However, this scheme may not guarantee the quality of service (QoS) of users and backhaul constraint of infrastructure providers (InPs). This motivates us to investigate the user association problem in virtualized cellular networks in this paper. We formulate the user-BS association as a matching game. We show that the preferences used to rank one another are independent and affected by the existing matching. Therefore, this game can be classified as the one-to-many matching game with externalities. In addition, we present a distributed algorithm to find the stable outcome of this game. Simulation results show that the presented association scheme is better than traditional scheme.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125238360","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}

From the network point of view, lower latency combined with high flexibility is not just limited to the concept of 5G but already on the way to be implemented in real network by 2020. In a cellular network, Device to Device (D2D) communication has been viewed as a promising technology to overcome many existed problems especially the capacity and quality considering the scarce spectrum resource. However, this comes at the price of huge interference and complex mobility issues although it was initially proposed as a new paradigm to enhance the network performance. Cellular devices without smooth mobility readiness are hardly acceptable. A smart mobility system in cellular in-band underlay D2D communication should have lower latency, lower power consumption, and higher data rates. My proposition is to review the existing mobility management system for the LTE-Advanced technology and propose a unique algorithm over the existing proposal so that lower signalling overhead and lower delay along with uninterrupted D2D communication are guaranteed for the 5G cellular communication system by 2020.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114737976","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, according to increasing scale of SaaS systems and their long-term of service operations, the monitoring system has faced the problem in response times of log analysis and storage consumption. Our empirical observation is that the problem is primarily derived from the unselective log processing of semi-structure datastore, whereas there should be heterogeneities in log data that we can take advantage of for efficient log management. Based on this observation, we first attest this insight by investigating the usage patterns of log data in a quantitative manner with an actual dataset of log access histories obtained from a SaaS system serving to enterprise users, and we show that there are heterogeneities in required retention period of logs, response time, and amount of data, depending on log data category and its analysis scenario. Armed with the evidence found from the investigation, we design a methodology of context-aware log management, key features of which are to speculatively pre-cache the log analysis and to proactively archive ones depending on log data category and analysis scenario. Evaluation with a prototype implementation shows that the proposed method reduces the response time and the storage consumption.","PeriodicalId":194123,"journal":{"name":"2016 18th Asia-Pacific Network Operations and Management Symposium (APNOMS)","volume":"8 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115004174","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}
