In this method, the scenario of each entity (node) is specified in a SMIL-like language. A specification of the total system (service specification) is described as a set of all users' SMIL-like scenarios and control scenarios specifying the interaction between entities. For a given service specification, network topology, link capacity and required bandwidth for each media-object, a set of protocol entity specifications (protocol specification) is automatically derived. The derived protocol entity specifications includes (1) the behavior of each node, (2) communication among other nodes, and (3) each object's transmission path. We have been developing an execution engine for the SMIL-like language which supports dynamic QoS controls and user interaction.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129868119","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}

Solutions for the problem are required to guarantee the mutual exclusive use of a resource, and avoid deadlock and starvation. Coteries are an efficient communication structure for solving mutual exclusion problem which is a special case of the distributed resource allocation problem. An extension of coterie called local coterie was proposed, to solve the distributed resource allocation problem, in a previous research. However, the method for constructing a local coterie proposed in the previous research is not so effective to construct efficient and robust local coteries. We propose a new method for constructing a local coterie that is more efficient due to the smaller size of a quorum and more robust to network failures due to bigger number of quorums than existing ones. Then, we show an algorithm using a local coterie to solve the distributed resource allocation problem. The algorithm guarantees the mutual exclusive access to a resource, deadlock-free, and starvation-free. Moreover, we discuss the message complexity of the algorithm.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126775667","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}

Our proposed QoS routing scheme gives a priority to multimedia traffic prone to block and differentiates network links into four classes based on link state information. Links have the different weights according to their classes and type of traffic transferred. We select the path with the minimum weight sum of links on the path. We also consider the observed blocking probability to reduce the frequency of the QoS state exchanges and supplement the out-of-date QoS information since the QoS state update results in the network overhead. Through the comparison between other existing schemes and ours, we show that our scheme with its low overhead and comparable performance is a better alternative to QoS routing schemes.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131647644","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 CSMA/ARI protocol allows active stations to contend/reserve channel capacity by sending requests during a successful ongoing frame transmission. To avoid corrupting the ongoing frame, for shorter frames, we scarify the precision of error detection by allocating a partial cyclic redundancy check (CRC) field for contention. The performance of the proposed protocol is studied by simulation and compared with the CSMA/CD and CSMA/RI with MAC delay, and channel utilization. Simulation results demonstrate that CSMA/ARI always offers better performance than CSMA/CD and CSMA/RI.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"47 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132383621","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}

Indeed, in cellular networks the trend is to have a smaller cells to meet the growing number of communication services. The smaller the cells, the more important is the third dimension because this model is more efficient. So, it is better to take the height into account. For instance, to create a cellular network in a building, it makes no sense to have a planar cellular network. It would be better to have antennas placed in the three dimensions. This paper presents some explanations about the reason why hexagons tessellation are used in the theory of cellular networks.

How to provide high quality, convenient, and personalized services to users are the important issues for Internet service providers to keep customers connected to their Web sites. The directory is an important part of Internet technology used to support such needs. It exists in a multitude of applications ranging from operating systems, asset management systems, security systems, etc. Furthermore, The Gartner Group, a market research firm, predicts that 40% to 90% of new software and hardware will be directory related products, at end of the period 2001 to 2003. In the directory industry, we can divide products into 3 fields: directory server, management system, and directory application. The management system is one of the important parts of directory services. The directory management system is focused on non-Web-based systems. While directory services are applied on Internet services, it is necessary to provide a Web-based management interface. This interface will provide the advantages of ubiquity, cross platform, thin client, and reduced TCO (total cost of ownership). We proposed and implemented a Web-based lightweight directory access protocol (LDAP) management architecture to provide such benefits and to manage multiple LDAP servers. We used the standard protocol and popular software of Internet technology usually used to build the system, so the system is easy to be ported and minimized the changes of the original system. In addition, we also considered the security factors while designing and constructing the system.","PeriodicalId":332734,"journal":{"name":"Proceedings 15th International Conference on Information Networking","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2001-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128777754","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}

Its autonomy and asynchronous message delivery handle this case in a more efficient and reliable manner compared with unicasting, which is a sender-based message transfer protocol like ours. Of course, we must pay for the creation, migration, and management of it. However, we have justified the employment of our messenger agent by proving the profit from it to overcome the cost.
