There are two key concepts in this paper. The first is the implementation of a hardware-assisted timestamping technique that timestamps on-the-fly the inbound/outbound frames. With this technique and using a low-cost communication protocol, it is achieved an accuracy of hundreds of nanoseconds in a point-to-point scheme. The second concept will use the logical tree created by the spanning tree protocol (STP) to spread the synchronization along the multihop network in a link-by-link basis. This novel concept eliminates the hierarchical structure of most of the synchronization protocols to create a flat synchronization scheme.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116498870","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}

Streaming multicasting applications in particular seems to benefit most from the P2P approach.

In this work we explore the generalization to push/pull protocols, where each peer can dynamically push or pull, playing alternately on short time frames, the role of parent or child.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126007691","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}

Human altruistic behavior is an important factor determining the feasibility of such a system. In this paper, we study the impact of different distributions of altruism on the throughput and delay of mobile social communication system. We evaluate the system performance using four experimental human mobility traces with uniform and community-biased traffic patterns. We found that mobile social networks are very robust to the distributions of altruism due to the nature of multiple paths. We further confirm the results by simulations on two popular social network models. To the best of our knowledge, this is the first complete study of the impact of altruism on mobile social networks, including the impact of topologies and traffic patterns.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130879326","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 protocol has the advantage of working either in current IP networks or new networking frameworks like the ANA framework. Our protocol consists of a distributed filtering process associated to a dynamic optimization process that selects the best content matching a client request at a given time. The performance evaluation of the protocol presented a satisfactory behavior in IP networks, while the implementation done using the ANA prototype allowed to adapt our protocol to a new autonomic framework that we hope, will be one of the leading autonomic framework of the future generation networks. However, we have a lot of work to do. We are working on a Java prototype to be deployed in platforms like Planetlab and Onelab in order to test its performance in a large-scale IP infrastructures. We are also working on the deployment of the implemented prototype in an ANA testbed and the execution some scenarios that could help us to prove its autonomic features.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130812728","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}

Now, with the opening up of the spectrum at 60GHz, it has become possible to design WLANs that can meet the goal of Gbps/user connectivity. This paper examines several unique design challenges brought about because of the physical characteristics of this frequency band. We show that antenna geometry has a significant impact on throughput. Geometric SDMA algorithms are developed that yield an almost linear scaling of throughput with the number of users yielding 800Mbps/user on average. We then explore the challenge of providing coverage in dead spots using the novel idea of passive reflectors. Finally, we examine the issue of power control and how the room geometry can be exploited to reduce the average energy/bit. The results presented are based on detailed PHY layer simulations of the 60GHz system including accurate 3D beam patterns formed by the antennas.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"22 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125007774","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, access from mobile devices is hampered by low bandwidth and small screen size. In this paper, we address these issues by manipulating two key elements of lecture videodisplayed slides and laser pointer gestures. Displayed slides need to be very crisp compared to background content. Fortunately, the needed data is available from the presentation slides, and we describe a method for splicing them into the video on the client side, increasing fidelity, and reducing bandwidth needs. This operation removes laser pointer gestures, which are often lost due to compression, and are hard to see on the small screens of mobile regardless. But these gestures are part of what makes watching lecture video different than simply looking at the slides. Hence we interpret the laser pointer gestures as we analyze the videos, creating representations that can be transmitted at a low cost. These representations can then be iconified on the client side and displayed clearly.","PeriodicalId":252414,"journal":{"name":"IEEE INFOCOM Workshops 2009","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125833020","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}
