One is for rescue and support on disaster such as earthquakes, floods and also for ground surveillance, land measurement and so on. Another is for in-cabin ubiquitous wireless environment such as mobile phone, wireless LAN for passenger airplane. We have developed on-board equipment on broadband communication system in Ka band, and carried out the test of high definition video transmission, TV phone, IP phone, remote IP camera monitoring by using Zeppelin NT airship. We got the results that 100 elements digital beam forming antenna in Ka band gave 81 fixed cells on the ground and each beam had 50 Mbps transmission rate. And we are now developing broadband communication system in 48 GHz band between airplane and ground. Those are anticipated in realize substitution for CBB (Connection by Boeing) system in Japanese domestic airliner. We got 100 Mbps transmission rate in an echoic chamber test and have the plan to test using Jet plane next year.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133130022","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}

On the contrary of the other points of view (eg. application centric), \"User Centric\" approach follows no long client server architecture and becomes one of the most important challenges of Next Generation Service (NGS). Current technologies, such as Web2.0, cannot satisfy the NGS requirements. In this paper, we propose \"User Centric session\" based on the Virtual Private Service Network (VPSN) model. This idea allows automated management of session service according to the mobility and maintains dynamically the personalized service composition. By implementing the scenarios of both multiple sessions and User Centric session, we do a comparison to prove the feasibility and the advantage of our approach.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131835060","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}

A service is governed by a client service contract (CSC) that specifies, among other requirements, the rate at which the service may be accessed so that a particular service host is not unduly overwhelmed. We consider the case where the CSC limits the rate to a service provider to no more than X requests per second, with an observation/enforcement time interval of T seconds. In this paper we define, simulate, and analyze CASTS (credit-based algorithm for service traffic shaping), a service traffic shaping algorithm to meet the service access requirements (SAR) under the above constraints. Our analysis includes convergence times, responsiveness, and the verification whether the system respects the service contract.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132327415","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}

This paper proposes a virtual force based MR placement algorithm (VFPlace) which is scalable and self- adaptive. Given a certain number of MRs, VFPlace targets to determine the positions of these MRs to maximize their overall coverage and maintain a certain number of neighbors for each MR, while satisfying geographic and traffic constraints of a specific WMN. VFPlace can dynamically avoid placing MRs in prohibitive regions, favor preferential regions and balance the distance between MRs. Moreover, VFPlace can adapt the MR placement to the highly aggregated traffic load towards Internet gateways. The effectiveness of VFPlace is demonstrated through extensive simulations.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133993689","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 main objective of this architecture is to provide low-cost connectivity solution for isolated and dispersed regions with no networks infrastructure. The proposed architecture is based on the concept of delay tolerant networks (DTN) and can be applied to various scenarios, including rapid deployment of emergency communication systems when all communication links have failed. In this paper, we present an overview of VWBS networks and show how their performance, in terms of average packet delays, can be improved using store-and-forward devices called relay nodes. Furthermore, we introduce several heuristic algorithms, which can be used to place minimum number of relay nodes. Through computer simulations, we compare the performance of the algorithms and their tradeoffs. We conclude our work by examining possible open research issues in VWBS.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129402549","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 investigate a cost efficient camera sensor deployment strategy based on random deployment of sensors to monitor and/or surveillance a region of interest. We assume that there are costs associated with the sensors as well as with the deployments and our goal is to minimize the total cost while satisfying the desired coverage requirement. We develop analytical methods to derive the expected coverage of a single sensor as well as the joint coverage for a given number of homogenous and heterogenous camera sensors. Following this we propose an adaptive sensor deployment strategy based on our analytical method. We then evaluate the expected cost of our deployment strategy by deriving expressions for the number of deployments and the number of sensors deployed during each deployment as a function of the probability distributions of joint coverage by sensors. Finally, we carry out simulation studies to validate the analytical results and to demonstrate that our strategy leads to near optimal numbers of sensors and deployments and hence the overall cost of deployment.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125145089","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}

A session information distribution system that distributes the available session information to all potential receivers must be scalable and work with low latency.

This system distributes the session information to the Internet users effectively, and can limit information distribution to specified users by labeling. We evaluated the actual implementation on the PlanetLab and OpenDHT to measure the session information distribution delay and retrieval time. The experimental results have shown that the session agent can distribute session information to the entire Internet with good scalability and end-users can retrieve the information with low latency.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114574592","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, higher level protocols typically have no way to determine the cause of packet loss, and generally make assumptions about the source of packet failure that may be incorrect. Accurate information about the source of packet loss could be valuable information to an upper layer. In addition, collisions and fades adversely affect SNR estimation algorithms, which are also useful for higher level protocols. We propose a physical layer algorithm that can both isolate the cause of packet loss, be it noise, collision or fade, and accurately determine the actual SNR regardless if the packet has been corrupted by collision or fade.","PeriodicalId":410930,"journal":{"name":"2008 IEEE Globecom Workshops","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114699736","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}
