In this work, we conjecture that the voice latency constraints between Immersive VoIP users would vary according to their virtual world distance of separation. As verified in our subjective listening tests, this conjecture is more realistic than fixed latency constraint, in terms of user perceptual experience and network feasibility. Empowered by the Bandwidth Reduced server assignment algorithm, the proposed two-hop distributed server architecture achieves a better balance between access bandwidth cost and voice latency when compared against the central server and the peer-to-peer architectures. The two-hop architecture targets the challenging scenario where there lacks clear correlations between the virtual world and the underlying physical network. In addition, we have also investigated the necessary frequency to execute the server assignment solutions to mitigate sensitivity to virtual world mobility.","PeriodicalId":131548,"journal":{"name":"2007 15th IEEE International Conference on Networks","volume":"267 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115997932","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}

Clients initially query a well-known master server for a list of currently registered game servers, and then sequentially probe each game server in the order they were returned by the master server. The starting and stopping of clients over time creates a 24-hour cycle of 'background noise' (probe traffic) impacting on registered game servers, independent of a given server's actual popularity with players. Based on over 10 million probe packets from two topologically distinct Wolfenstein enemy territory servers in 2006, this paper shows that probe arrivals are uncorrelated and exhibit exponentially distributed inter-probe intervals during both busiest and least-busy hours of the 24-hour cycle. A modified Laplace curve is then shown to be a reasonable estimator of lambda for the exponentially distributed probe arrivals during any hour of the day. The ability to easily synthesise probe traffic patterns will augment existing approaches to modeling the IP traffic loads experienced by game servers and network devices attached to game servers.","PeriodicalId":131548,"journal":{"name":"2007 15th IEEE International Conference on Networks","volume":"258 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116021178","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 focuses on analyzing the impact of specific type of mobility characteristic, namely user mobility patterns. We base our analysis on opportunistic temporal-pairing access network (OPAN), an opportunistic content distribution framework that utilizes both pairings between nodes and infrastructure-based wireless network. Focusing our study to explore the impact of peak hour traffic (i.e. due to human mobility patterns involving routines and schedules) and hence node density (clustering) on opportunistic content distribution paradigm, we introduce two models based on a rail public transportation model, namely random train model and peak hour train model. Our simulation results show that peak hour traffic increases the downlink traffic (i.e. uses more downlink capacity) in OPAN however provides faster diffusion time for nodes to download content. Our simulation results further suggests that mobility patterns with high node clustering is more beneficial for content distribution in mobile opportunistic networks due to higher chance of forming direct pairing between nodes.","PeriodicalId":131548,"journal":{"name":"2007 15th IEEE International Conference on Networks","volume":"214 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116396202","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}

Despite the fast expansion of WLANs in various environments, quality of service (QoS) issues for multimedia applications in WLANs are not yet resolved. Multimedia applications contain traffic that are sensitive to delay and jitter and therefore a best-effort protocol such as the legacy IEEE 802.11 is not suitable. The 802.11e protocol provides prioritization and classification of traffic to offer better QoS for real-time services. However, it leaves the design and implementation of many important optimization features to vendors. In this paper we introduce a mechanism to improve the delay and jitter of real-time traffic in WLAN nodes supporting multimedia applications. In our proposed mechanism, we segregate voice and video traffic from the best-effort traffic. We create a scheduler that schedules the access of real-time traffic and non real-time traffic to the medium with centralized polling and distributed contention respectively. We show that our proposed protocol performs better in terms of delay and jitter than the legacy 802.11 and 802.11e in a scenario where all wireless nodes carry multimedia traffic simultaneously.","PeriodicalId":131548,"journal":{"name":"2007 15th IEEE International Conference on Networks","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123532829","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}
