Soil, environmental, and crop information monitoring are important in production management and decision-making in precision agriculture. Therefore, reliability, security and inexpensive characteristics required are essential in the crop field information monitoring. Three improved field monitoring servers (FMS) using code division multiple access (CDMA) services combined with IPsec-based virtual private network (VPN) function have installed to two rice practical fields in Shanghai and one maize experimental field in Beijing for constructing a remote wireless sensing network. This crop field remote monitoring system as a ubiquitous node infrastructure in wireless sensing networks is useful and powerful to collect soil, environment, and crop information in remote for precision agriculture via two-years testing","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122360706","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, region-wide trainings that require hands-on practice still need lecturers and participants at the same location. This requires huge resources on travel budget, time, equipments and staff. This paper proposes a region-wide distributed model of realtime hands-on workshop using distance learning and remote virtualization environment. The proposed model was implemented for SOI Asia operator training during 22-26 August 2006 inviting 42 participants from 19 institutions in 10 Asian countries. The workshop proved to have significant reduces in travel budget, lab preparation time and equipments compared to ordinary workshop model held in the previous year. Feedbacks show 95% of the participants evaluated this workshop is effective for their future operations. Accordingly, this workshop model is practical and resource-optimized model for region-wide human resource development. This paper can be a useful information source for future development and improvement of region-wide remote workshops","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"200 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122678979","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}

Some researches suggested a method to extract meaningful information from SNSs. Such meaningful information helps computers to understand human interests, concerns, and perceptions.

Accordingly, in this paper we propose the access application programmable interface (API) to find human-oriented information from outside a given SNS. We use the result of experiments on the API to demonstrate a network comprising relationships among communities.

It is based on a non Gaussian modeling of the marginal distributions of random projections (sketches) of traffic aggregated jointly at different levels (multiresolution). To evaluate false negative vs. false positive in a controlled, reproducible and documented framework, we apply the detection procedure to traffic time-series from our self-made anomaly database. It is obtained by performing DDoS-type attacks, using real-world attack tools, over a real operational network. Also, we illustrate that combining sketches enables us to identify the target IP destination address and faulty packets hence opening the track to attack mitigation","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123399037","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}

For such services, degradation of network quality such as packet loss or delay is directly linked to the quality perceived by users. It is therefore important for network administrators to know these quality indicators for each session. However, the measurement of quality per session has become difficult due to the rapid increase of line speeds. Packet sampling techniques have been receiving much attention as a way to solve this problem, but there has been only a little discussion of packet loss in that research though it is very important. In order to determine whether quality degradations occur at particular sessions, we have proposed methods for estimating the end-to-end packet loss per session by packet sampling. In this paper, we then propose a method to determine whether the quality degradation occurs between the sending terminal and the measurement point (send segment) or between the measurement point and the receiving terminal (receive segment). The proposed method will estimate packet loss of receive segment to observe duplicate ACKs and the DATA packet with corresponding sequence number to ACK number of duplicate ACKs. Then, the packet loss of send segment can be estimated by subtraction packet loss of receive segment from end-to-end packet loss. This allows quality degradation segment to be estimated from only a 10% sample of the packet flow","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123738051","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 report, we discuss a distributed architecture for real-time and scalable flow monitoring tools and implement a prototype tool using network processor (NP). The contributions of the present paper are two-folds. First, we clarify the elemental functions that are required and commonly used by passive flow monitoring tools, and refine a distribution-processing architecture for combining these functions based on our previous work in order to cope with heavy-load input traffic. Second, we implement the packet distribution component, which plays a core role and might be bottleneck in the proposed architecture, by using pipeline-mode NP hardware, and experimentally prove its applicability to 10 Gbit/s-class input traffic","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"74 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124711569","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 authors have previously studied a security mechanism which can satisfy the restrictions required by control systems and a secure autonomous bootstrap mechanism which is based on the security mechanism. This paper shows an extension of the bootstrap mechanism to support multicast security.

If the SP additionally requests some attributes of one's, the user is forced to reveal the immediate values of them. There are cases where users must present detailed privacy information which SPs don't actually require to authorize them. We focus on Shibboleth and propose an extension of the attribute exchange protocol between an IdP and an SP in Shibboleth. While in the conventional framework of Shibboleth attributes are exchanged in immediate value, in our extension an SP requests an IdP to test whether user's attributes are satisfied some conditions, then the IdP returns either \"true\", \"false\" or \"unanswerable\" to the SP. We specify a language to describe the conditions as a query at the SP. We also extend an attribute authority at the IdP to evaluate the conditions presented from the SP","PeriodicalId":254195,"journal":{"name":"2007 International Symposium on Applications and the Internet Workshops","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-10-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128081706","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}
