Nio-Mora","doi":"10.1109/NGI.2008.38","DOIUrl":"https://doi.org/10.1109/NGI.2008.38","url":null,"abstract":"This paper addresses a system model where multiple heterogeneous mobile users share a common wireless channel to a base station, extending work of Koole et al. (2001) which considered the corresponding homogeneous-user case. The channel's bandwidth is to be dynamically allocated to different users, based on partial information on their connectivity status. During each time slot, a user may or may not be connected to the base station, where the Gilbert-Elliott model is assumed that a user's connectivity evolves as a two-state (on-off) Markov chain. Transmitting from/to a user reveals its true connectivity status, while those of other users are only partially known by tracking their probabilities of being connected. The goal is to design a tractable dynamic channel allocation policy that comes close to maximizing the infinite-horizon discounted or long-run average value of the through put minus transmission costs. The paper exploits a restless bandit problem formulation drawing on and extending to the Partially Observed Markov Decision Process (POMDP) setting the powerful indexation theory introduced by Whittle (1988) and developed by the author, to obtain a new dynamic priority-index policy that is readily implementable. Computational results are presented showing that the proposed policy can substantially outperform the conventional greedy policy in instances with two heterogeneous users.","PeriodicalId":182496,"journal":{"name":"2008 Next Generation Internet Networks","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128800026","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 enhanced distributed channel access (EDCA) is probably the most promising subset of such mechanisms, and it is already implemented in a huge number of Network Cards. In this paper we present an algorithm for the provisioning of QoS in EDCA WLANs. The algorithm is based on monitoring and reactive configuration of EDCA mechanisms in scenarios where voice over IP (VoIP) and best effort (BE) applications concurrently access the wireless channel. Results obtained in a real test-bed prove the effectiveness of the algorithm both in protecting VoIP communications and in providing minimal quality levels and fairness to BE applications.","PeriodicalId":182496,"journal":{"name":"2008 Next Generation Internet Networks","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134338396","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}

However, despite of their diffusion, the analysis of tele- traffic generated by these applications in real-time environment remains an open issue. In this paper we look at analytical and simulation models, which can be used for quantifying volumes of P2P teletraffic at the network layer, to ease still existing difficulties associated with monitoring such teletraffic. We present an event-driven simulator, able to simulate P2P teletraffic both at the application and network layers in large overlay networks (we have successfully tested it in networks used by up to 500,000 peers). The simulation model was developed for studying the impact that P2P systems have on the network layer performance. We studied also the application layer dynamics by looking at time evolution of file-downloading processes and at the offered load generated in such networks. We report the results of several simulation scenarios, in which we focused on the consequences such teletraffic has on the Internet access link of an enterprise network.","PeriodicalId":182496,"journal":{"name":"2008 Next Generation Internet Networks","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115676524","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}

In addition, with a large number of users demanding experimental resources and lack of space and time for deploying more hardware, fair resource sharing among independent co-existing experiments is important. We study the proposed approaches to wireless virtualization with a focus on schemes conserving wireless channels rather than nodes. Our detailed comparison reveals that while experiments sharing a channel by space separation achieve better efficiency than those relying on time separation of a channel, the isolation between experiments in both cases is comparable. We propose and implement a policy manager to alleviate the isolation problem and suggest scenarios in which either of the schemes would provide a suitable virtualization solution.","PeriodicalId":182496,"journal":{"name":"2008 Next Generation Internet Networks","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128173380","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}
