We focus on the network capacity that can be measured by the critical value of phase transition from free flow to congestion. Here we address influence of the topology on the dynamics of traffic delivery for small-world networks, taking into account the average degree, the average clustering coefficient, and the information-processing capacity of individual nodes. Simulation results show that the critical value is obviously different for different small world network structures, and the critical value increases as the average degree increases. Moreover, compared to the influence of the average degree on traffic delivery, the influence of the average clustering coefficient on traffic delivery is less important role.","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123904760","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 deterministic phase function and stochastic modulation function is applied. The sum of all sub-paths forms the output signal.

Traditional packet loss evaluation criteria are not sufficient to describe characteristics of losses: the loss rate is too simple while traditional loss episodes sometimes are not stable due to the randomness of loss events. In this paper, we propose an extended loss episode approach, merged loss episode based on the traditional definition, to estimate the network condition. Also we presented the corresponding algorithm for calculation. Simulation results show that compared with traditional loss episodes, the merged version could be more stable and effective to measure network performance on loss issues.","PeriodicalId":177679,"journal":{"name":"2009 International Conference on Communication Software and Networks","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-02-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114470583","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}
