Studies of application-level traffic analysis have been performed as the first step of the management and control of network traffic. Many studies have been utilizing “User-Agent” field in the HTTP header in order to analyze application-level HTTP traffic. As a result, most of HTTP-based applications can be classified with user-agent information, but some of HTTP traffic cannot be analyzed since it does not include user-agent field. In this paper, we use server-client correlation of HTTP service in order to improve completeness of HTTP analysis. Therefore, even though user-agent field does not exist in the HTTP header, analysis of application-level can be accomplished. We show our method feasibility through the experiment in a campus network.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114997384","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 this paper, we utilize this new breakthrough to transfer energy to sensor nodes in wireless sensor networks. We carry on the cellular structure in [4] to describe a wireless sensor network (WSN) and employ a wireless charging vehicle (WCV) periodically visiting each cell to charge nodes within it wirelessly. We propose a dynamic optimization model which is practical and feasible to forecast the departure time and charging time in each cell of the WCV. With the target of maximizing the time during which WCV stays at the service station, we develop two constraints as sufficient and necessary conditions to satisfy the energy requirement at each node and present through simulation how to schedule the WCV to accomplish its energy transfer tasks in a real-time WSN.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116656575","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}

Many people want to access the internet by using 802.11 WLAN network as of free service. So, a lot of APs are deployed in many places such as home, office and store. Because anyone can install the AP in any place, APs or STAs are suffered the interference between them. This interference makes whole WLAN network performance to be poor quality. The main reason existing the interference is that a huge number of AP and STA is deployed. To solve this situation, 802.11 standard has established a new study group (SG), high efficiency wireless (HEW) local area network. This SG want to enhance the area throughput which is the average throughput in a specific area. We think average throughput is mainly effected by the inter cell interference which is the interference from other APs or STAs. And average throughput is proportional to the sum rate of each node in a specific region. In this paper, we develop three different downlink interference management approach which is so called distributed interference alignment algorithms. To apply these algorithms in the 802.11 WLAN, we think there are some key points which are distributed processing between nodes, only local channel state information usage, linear processing and IA adaptation possibility for the number of general users. Our algorithms displayed in this paper are followed by above assumptions. And we show the performance comparison between our algorithms.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"100 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116666313","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}

Unfortunately, the MAP detection usually requires a prohibitively high computational complexity. In this paper, a lattice reduction (LR)-based MIMO detection method is proposed to achieve near MAP performance with reasonably low complexity in IDD, where the a priori information (API) is taken into account during list generation using randomized sampling to improve the performance. The sampling distribution is optimized to maximize the probability of sampling the MAP solution. It is shown that the proposed method outperforms conventional LR-based ones, where no API is considered during the list generation. Furthermore, a trade-off between performance and complexity is exploited with different list lengths.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127377339","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}

NCS consists of various large-scale components such as communication service and data distributed service (DDS). Furthermore, MOMAT meets requirements of NCS to support several versions of control such as components, interfaces, messages and publisher/subscriber paradigms. The MOMAT dealing with real-time data changes using continuous query (CQ) to provide new result from the database without issue same query repeatedly. However, a large number of continuous queries may be executed simultaneously over a high throughput of incoming data that may deteriorate system performance and cause data (message) delay. Therefore paper proposes a query split mechanism for performance improvement of retrieval in middleware systems.

The Korean government faces an emergency. It must ensure reserve power because of the shortage of power in summer season. In 2013, the government began the AMI and ESS deployment projects to solve the problem of power shortage, allotting them a budget of 19.9 billion. ESS includes power management systems (PMS), power conditioning systems (PCS), battery management systems (BMS) and rechargeable battery systems. Among them, BMSs are core technology and are being developed globally. Therefore, we developed the BMS platform, based on a digital signal processing (DSP) platform, which is a Master-Slave structure. We adopted CAN communication technology between the Master and Slave. The system is easily used to develop a new state of charge (SOC) and cell balancing technique. An interface that is able to communicate with other BMSs was added. Future research will continue the development of state of health (SOH) using the AC impedance method and the study of increased precision.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124904266","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}

Users expose to different network environments, so their exploited services would experience different performance of throughput, delay time, and jitter. In the literature, many studies explored how to allocate resource blocks (RB) to different services efficiently. Famous examples are Proportional Fair (PF) and Modified Largest Weighted Delay First (MLWDF) scheduling algorithms. PF considers fairness-based service priority without Quality of Service (QoS) consideration. MLWDF favors those packets with timing constraints, resulting in uneven resource distribution. In this paper, we propose a fairness-based adaptive QoS scheduling algorithm for LTE downlink. We design an Adaptive Modified Largest Weighted Delay First (AMLWDF) formula, which considers delay time, instantaneous transmission rate, average transmission rate, delay constraints, QCI priority, and fairness at the same time. Simulation results show that AMLWDF outperforms Proportional Fair and Modified Largest Weighted Delay First in various performance indexes.","PeriodicalId":144167,"journal":{"name":"2013 International Conference on ICT Convergence (ICTC)","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114181582","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}
