There is no central authority, the communication occur hop by hop based on cooperation among the nodes. Thus, secure routing protocols are needed which are robust and ensure that the nodes in the network behave in trustworthy manner otherwise detect and eliminate the untrustworthy nodes which degrade the overall network performance. There are several trust based AODV routing protocols given in the past. In this paper, we have given a survey of trust based AODV, in which concept of TRUST is used to ensure secure routing and improved network performance.","PeriodicalId":232851,"journal":{"name":"Journal of Advances in Computer Networks","volume":"88 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125720952","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}

To save additional costs in this roll out, the existing copper can be reused as backhaul for the new active point of G.Fast, where currently mostly a fibre backhaul is considered. This paper presents the advantages of copper backhauling for G.Fast nodes and studies the planning and expected bandwidth coverage of this Copper Backhaul solution in two cases. These cases show that this solution is a logical next step in the network migration, offering cost saving, flexibility and the needed bandwidth gain for the consumers.","PeriodicalId":232851,"journal":{"name":"Journal of Advances in Computer Networks","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121989516","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 the area of human-robot interaction, user communicates with service robot in their daily life activities to give commands and execute the given task accordingly. Therefore, the ability of user to gives command to service robot naturally can provide an interactive user interface system for real 3D space environment. For this purpose, we aim to perform pointing gesture tracking and after that estimate the user's pointing direction. Our method of pointing direction estimation is based on 3D orientation of hand and shoulder center of user. We make comparison with our previous method to find the best hypothesis. Experimental results show the angular error for the estimation of pointing direction is successfully improved from our previous method. As a result, our natural user interface system can manipulate 3D objects in living room environment thus providing intuitive robotic service for human robot interaction. I. INTRODUCTION Tracking of human gesture has been widely researched either in human-computer interaction or human-robot interaction. Besides voice, gesture is an example of platform to interfacing between human and robot intuitively and naturally. Pointing is one part of gesture which provides information and intention from human to service robot. Pointing-based user interface can easily indicate object and location for the robot delivering robot task in home environment. However, in the real environment, some ambiguity can occur and affect the performance of robotics service. The ambiguity in pointing gesture comes from the angular error in estimation of user's pointing direction particularly when certain objects is closely located. Due to the ambiguous pointing command, correct object and location cannot be identified thus service robot surely unable to deliver task successfully. To overcome this problem, we conduct several experiments on tracking of pointing arm and make comparison study to find the best hypothesis. In this paper, we present a robust tracking method to be used in pointing direction estimation. We measure the pointing angle from the position of hand with respect to the shoulder center. To obtain the 3D coordinates of pointing arm","PeriodicalId":232851,"journal":{"name":"Journal of Advances in Computer Networks","volume":"101 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122636926","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}

As a fault-tolerant and horizontally scalable ecosystem, it becomes a suitable platform for the analysis of big network data. While most network data are currently being analyzed by vertically scaled machines, Hadoop provides an alternative method of analysis, allowing large datasets to be analyzed in one horizontally-scaled cluster. This study attempts to benchmark and profile the current known methods for performing network analysis on Hadoop. After comparing three data storage formats; plain text, Parquet, and raw PCAP files; for use in Hadoop, the study has determined that the Parquet and text formats greatly outperform the use of raw PCAP files using the hadoop-pcap library which fails to complete tests with high volumes of data. This comes at the expense, however, of large data loss due to the need to create a well-defined schema for processing and the conversion time necessary to shift to a different format. However, Parquet still outperforms the text format by an average of approximately 30% in the scan and aggregate queries, and 70% and 40% respectively in the join and aggregate-join queries while showing a 8%-10% increase of performance in aggregate-join queries of over 60 minutes’ worth of PCAP data.","PeriodicalId":232851,"journal":{"name":"Journal of Advances in Computer Networks","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132021206","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}
