In this context, many Virtual Network Embedding algorithms have been introduced in literature so far. This paper discusses an open source framework for the evaluation of such algorithms. The paper describes features provided by the framework, how to use the framework for evaluating these algorithms, and how to extend the software with respect to novel algorithms and simulation scenarios. Lessons learned are presented, describing how the software evolved towards a mature and highly extensible simulation framework.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123320773","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 simulation results demonstrate that system based on STBC-MGDM achieves better performance than that only employing MGDM in current systems.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126933506","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}

We model, at flow level, the way a finite population of users with heterogeneous access rates and traffic demands shares the capacity of this common backhaul link. We then evaluate several practically interesting use cases, focusing particularly on the performance of users subscribing to recent FTTH offers in which the user access rates may be of the same order of magnitude as the backhaul link capacity. We show that, despite such high access rates, reasonable performance can be achieved as long as the total offered traffic is well below the backhaul link capacity. The obtained performance results are used to derive simple dimensioning guidelines for backhaul networks.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115704468","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}

When the packets of a traffic flow originating from a source node are relayed by intermediate nodes (relay nodes), competition between the nodes on the multi-hop routing path incurs transmission delays from the carrier sensing mechanism, as well as packet drops and retransmissions due to hidden terminals. Owing to this complicated interaction between nodes, problems in the throughput performance analysis of multi-hop networks have not been fully resolved. In this paper, we propose an optimization approach to compute the throughput at each individual link in addition to the end-to-end throughput in an IEEE 802.11 DCF-based multi-hop wireless network. To this end, we first analyze a multi-hop chain topology with a single flow by taking into account transmission collisions from hidden terminals, and then formulate the optimization problem to obtain the end-to-end throughput performance of multi-hop networks. Through extensive ns-2 simulations, we then show that the proposed approach accurately predicts the throughput performance obtained by the simulations, within a discrepancy of less than 10-12 % in the worst case scenario under a variety of chain and cross topologies.","PeriodicalId":410892,"journal":{"name":"2014 16th International Telecommunications Network Strategy and Planning Symposium (Networks)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2014-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129240915","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}
