However, the lack of configurable and measurable properties in current decentralised pub-sub services introduces the issue of limited customisation. This shortcoming leads to the inability to meet different requirements needed by various application domains. In this paper, we address the challenge of supporting configurable properties in an overlay-oriented pub-sub scheme for decentralised networks. We use the measurable feature produced by the configurable properties to develop a mathematical model to analyse the behaviour of the pub-sub scheme with respect to important input factors such as distributions of subscriptions and events. These input factors ultimately affect the widely regarded performance requirement. Finally, we demonstrate the feasibility of our scheme and the validity of the derived model with a series of simulations.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129477704","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 this paper, a high-speed pipeline designed for TCAM-based forwarding engines is presented, and its buffer analysis model is also given, then, the buffer requirement of the forwarding engine is analyzed under two conditions: the forwarding rate is not less than and less than the input rate. Our analysis results and experiments both show that, the proposed forwarding pipeline is of high performance, and just one pipeline can easily deal with the data transfer rate of 30 Gb/s or even higher; the pipelined forwarding engine only need to buffer a several packets, then the loss rate will be an acceptable value or even zero, further increasing the buffer size will have little effect on reducing the loss rate.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133671497","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}

Therefore, these applications need an efficient design that allow them to simultaneously tackle these two requirements. Although several proposals have focused on the software architectures for these systems, no proposals have focused on the computer systems supporting them. In this paper, we analyze the computer architectures used in the literature to support virtual environments. Also, we propose a distributed computer architecture efficient enough to support simulations of thousand of autonomous agents. This proposal consists of a cluster of computers in order to improve flexibility and robustness, as well as a hierarchical software architecture that efficiently provides consistency. Performance evaluation results show that the trade-off between flexibility and consistency allows to efficiently manage thousands of autonomous agents.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"2001 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133030683","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 proposed scheme adjusts contention window sizes by considering the contributions of each traffic instead of each node on the network contention rate. There have been research efforts to improve IEEE 802.11 EDCF. However, these approaches have some limitations in that they do not consider that how much each AC traffic affects the packet collision rate. We propose a novel scheme based on traffic flow named T-EDCF. The difference between T-EDCF and existing schemes is that the former considers traffic categories' effects on the throughput, jitter, and delay of a node. When there are a lot of flow and nodes in WLAN, T- EDCF outperforms other schemes proposed for enhancing the IEEE 802. lie.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124745620","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}

These two supplementary operations enable the mobile user ubiquitous mobility. However, in case of failed location update, a significant consequence is the obsolete location identity in the network databases and thereafter the incapability in establishing the valid route for the potential call connection, which will seriously degrade the network quality-of-service (QoS). This issue is not theoretically studied in the literature. In this paper, we perform a quantitative analysis of the location management effect on QoS in the wireless networks. The metrics call blocking probability and the average number of blocked calls are introduced to reflect the QoS. For the sake of general applicability, the performance metrics are formulated with the relaxed tele-traffic parameters. Namely, the call inter-arrival time, cell residence time, location area residence time and location update inter-arrival time follow a general probability density function. The formulae are additionally specified in the static and several dynamic location management mechanisms. Numerical examples are presented to show the interaction between the performance metrics and location management schemes. The discussions on the sensitivity of tele-parameters are also given.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127802989","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}

Takizawa","doi":"10.1109/AINA.2007.124","DOIUrl":"https://doi.org/10.1109/AINA.2007.124","url":null,"abstract":"In information systems, processes have to be scheduled to share a limited amount of resource objects like memory and CPU with other processes. In database systems, conflicting access requests from multiple transactions have to be serialized. There are various ways to order multiple conflicting access requests like FIFO and timestamp ordering (TO) schemes. For example, an object is exclusively used by each transaction in locking protocols. In scheduling algorithms, highly prioritized processes are performed before lower ones. Thus, it is critical to discuss which access request should be performed before another. In this paper, we postulate that an access request issued by a more significant subject for a more significant purpose should be performed prior to less significant access requests. In the role-based access control model, a role is a set of access rights, which shows a job function in an enterprise. A subject is first granted a role from another subject. Only a subject granted a role can issue an access request in the role. In this paper, the significancy of subject and purpose is defined in terms of roles and authorization relations. Here, there are two views, subject-oriented (SO) and purpose-oriented (PO) views to order transactions. A method issued by a subject with more significant roles should be performed before another conflicting method issued by a less significant subject in the SO view. A transaction issued by a subject is associated with a subset of roles granted to the subject, which is named purpose. A method with a more significant purpose should be performed before another method in the PO view. In this paper, we discuss how to combine the SO and PO views into a unique SPO view to order conflicting access requests.","PeriodicalId":361109,"journal":{"name":"21st International Conference on Advanced Information Networking and Applications (AINA '07)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129766894","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}

Furthermore, this paper proposes and implements a double-buffered communication model to improve communication speed keeping independence from each processor model on the system.
