Customers like to watch a variety of entertainment content of their choice and at their convenience. Serving this ever-increasing base of on-demand viewers requires careful provisioning by the providers to accommodate for both scale and interactivity. In this paper, we examine long-term usage patterns of hundreds of thousands of consumers of a nationwide IPTV service, and confirm that viewers are indeed migrating to what is called “time-shifted” viewing of television programming and movies using digital video recorders or on-demand viewing. We also examine the impact of such user's interactive control of their viewing experience using “stream control” functions (e.g., fast-forward, rewind, skip, replay, etc.) Through careful measurements on an IPTV server, we compute the load due to video streaming and handling these stream control events. We then extrapolate from these micro-benchmark measurements to predict the processing load imposed by users that would resort to using a “network-based” DVR capability if such a service were offered. We use both detailed trace-driven simulations and a simple operational-analysis based model to predict the capacity requirements of the server complex in a video-hub office to serve a large population of customers (e.g., a densely populated city like Mumbai). We provide insights on the number of requests serviced by the server, the average time to service these requests and the response time as perceived by the client.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126379783","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}

Integrating MANETs to infrastructure-based networks (wired or wireless) allows network coverage to be extended to regions where infrastructure deployment is sparse or nonexistent as well as a way to cope with intermittent connectivity. However, to date there are no comprehensive solutions that integrate MANETs to infrastructure-based networks. In this paper, we introduce a message delivery framework, MeDeHa++ that is able to bridge together infrastructure-based and infrastructure-less networks. Through extensive simulations, we demonstrate the benefits of MeDeHa++, especially in terms of the extended coverage it provides as well as its ability to cope with arbitrarily long-lived connectivity disruptions. Another important contribution of this work is to deploy and evaluate our message delivery framework on a real network testbed as well as conduct experiments in “hybrid” scenarios running partly on simulation and partly on real nodes.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130453261","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 fill this void, we present a new architecture for mobile testbeds called CrowdLab. CrowdLab allows researchers to run guest virtual machines on volunteer mobile nodes and ensures efficient use of testbed resources through a new dual-mode networking abstraction and a weakly-consistent, replicated state store called a site directory. We have implemented two CrowdLab prototypes, one for x86 laptops and one for ARM-based Nokia N810 Internet Tablets, and evaluated them using power measurements, micro-benchmarks, and trace-driven emulation. Our evaluation demonstrates that handheld users can contribute 2.5 hours per day to CrowdLab and still have over 12.5 hours of idle time remaining. In addition, emulated mobility-trace replays show that CrowdLab's fault-tolerance mechanisms allow experiments to run uninterrupted, even in the face of high churn rates.","PeriodicalId":302678,"journal":{"name":"2011 Third International Conference on Communication Systems and Networks (COMSNETS 2011)","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130767193","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}
