Realistic performance estimators are difficult to obtain due to the diversity of overlay concepts and their complex dependence on the global Internet topology that withstands straightforward simulations or measurements. We contribute a simple analytic model for the expected delay distribution. Parametrized by realistic measurement values, this should serve as a first order estimator for quantifying the delay penalties in a global-scale hybrid multicast packet distribution. We diagnose a strong dependence on hop counts and proximity awareness for the overlay multicast approach in use with promising results for most efficient schemes.","PeriodicalId":181045,"journal":{"name":"Co-Next Student Workshop '09","volume":"50 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116763180","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 date, QoS and QoE research has however mainly been carried out in an isolated manner. Their exact correlation consequently remains unclear. Using a collaborative multi-platform game as case study, we intend to investigate this relationship and hope to bridge the divide that currently exists between social, user-oriented research and technically-oriented application development by formulating recommendations and guidelines. To implement the QoS and QoE optimizations, we will rely on the NIProxy, a network proxy equipped with network traffic shaping and service provision functionality.","PeriodicalId":181045,"journal":{"name":"Co-Next Student Workshop '09","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122044526","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}

Several incentive schemes have been proposed to enforce non-willing peers to cooperate. But we find it of great interest to see how physically constrained, with respect to resources, peers can be supported by a streaming application. In this paper we investigate how free-riders, namely non-contributing peers, can be served in a peer-to-peer streaming system. We examine different prioritization schemes that are used by high contributing peers to prioritize other contributing peers over free-riders and show that as the level of prioritization increases, contributing peers receive higher quality but the average quality drops. To avoid this, we propose an incentive mechanism that encourages contributing peers to upload to free-riders so that the average quality experienced by the peers in the overlay is maximized.","PeriodicalId":181045,"journal":{"name":"Co-Next Student Workshop '09","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134275102","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 reduction of state will alleviate this problem. In this paper, we outline a new reduced-state inter-domain forwarding mechanism. We carefully drop portions of the advertised forwarding state using a utility measure for prefixes based on the length of the prefix and the path length to its origin. A deterministic forwarding algorithm uses the resulting partial view. The graph of connections between autonomous systems is shallow, offering many viable paths for data flows, a property we aim to use to achieve minimal detrimental effect on delay and AS path stretch.","PeriodicalId":181045,"journal":{"name":"Co-Next Student Workshop '09","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129225827","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}

More advanced applications also need end-to-end routing, which goes beyond the simple data dissemination and collection mechanisms of early WSNs. The special properties of WSNs -- scarce memory, CPU, and energy resources -- make this a challenge. The Dynamic Address Routing protocol (DART) could be a good candidate for WSN routing, if it were not so prone to link outages.\u0000 In this paper, we propose Scalable Landmark Flooding (SLF), a new routing protocol for large WSNs. It combines ideas from landmark routing, flooding, and dynamic address routing. SLF is robust against link and node outages, requires only little routing state, and generates low maintenance traffic overhead.","PeriodicalId":181045,"journal":{"name":"Co-Next Student Workshop '09","volume":"68 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121652529","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}
