Among different mobile location estimation methods, the one which estimates the location of mobile stations with reference to the wave propagation model is drawing much attention on the grounds that it is applicable to different kinds of cellular network. However the estimation accuracy of the signal propagation model deteriorates as the distance between the mobile station and the receiving base station increases. In view of this, we have designed a new location estimation approach which has divided the location estimation into two phases, the data collection phase and the location estimation phase. In this paper, we report our study of the new location estimation approach. We tested the approach with real life data collected from a major mobile operator of Hong Kong. Results show that the new location estimation approach has improved the existing statistical signal propagation model by 30.94%. This improvement can be further enhanced if more data are collected","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"77 7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122081758","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 trying to ensure the survivability of these components, we enable a mission-critical application to detect malicious codes in a component downloaded from a remote location and recover the original functionality of the compromised component. In our work, we use digital signatures to ensure the integrity of software components in a large distributed system. By detecting unauthorized add-ons to the original components we can ensure that only legitimate software components are allowed to execute in a protected software environment. We also explore techniques to recover the original functionality of the component under attack by removing the affected portion from the component.

Sensors gather information sensed for an event in the physical world and send them to actors. Actors perform appropriate actions on actuation devices by making a decision on receipt of sensed information from sensors. Sensors are low cost, low powered devices with limited energy, computation, and wireless communication capabilities. Sensors may not only stop by fault but also suffer from arbitrary faults. Furthermore, wireless communication is less reliable due to noise and shortage of power of sensors. Reliable real time communication among sensors, actors, and actuation devices, is required in WSAN applications. We newly propose a multi-actor/multi-sensor (MAMS) model. In addition, multiple actors may perform actions on receipt of sensed information. Multiple redundant execution of an action on each device has to be prevented and conflicting actions on each device from multiple actors have to be serialized. In this paper, we discuss how to make WSAN reliable and available and how to reliably and non-redundantly perform actions with realtime constraints.","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"40 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128361442","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}

Although many detection systems have been proposed so far, most of them can detect only part of alteration. Some detection systems use canaries to detect alteration. However, if an execution code has bugs that enable attackers to read data in memory, the system could be bypassed by attackers who can guess canaries. To overcome the problems, we propose a system using alteration of data. Our proposed system detects illegal alteration with verifier for vulnerable data. Verifier is made before vulnerable data could be altered by attackers, and verifier is checked when the program uses the vulnerable data. Part of verifier is stored in kernel area to prevent attackers from reading data in user memory. Our approach can detect illegal alteration of arbitrary data in user memory. Our proposed system, moreover, does not have the problem systems using canaries have.","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128412745","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 a SQL manner, our information system GenoMEDIA addresses the problem of integrating heterogeneous data-bases and software utilities within a generic distributed platform. Lysa increases the GenoMEDIA SQL interface by adding an interactive collaborative graphical environment. Upon a usual query on biological database, gigabytes of data could be returned to the users. The aim of Lysa, through the databall concept, a certain kind of data introspection and collaborative engine, is to allow groups of users to make semantic links in these huge amounts of data. The main point of this paper is the collaborative framework written for Lysa. This framework allows multiple users to work upon the same shared biological data. This was written in order to add the capabilities and the knowledge of multiple users in order to extract information of the huge mass of data coming from biological databases.","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"44 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129663621","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}

This new technological context implies revisiting common network algorithms. When considering an multi-sector antenna uncommon with an uncommon high switch delay, packets have to be efficiently scheduled on beams at the MAC layer level, in order to improve the network capacity. We consider two optimization criteria: the network throughput and the maximum delay of packets. This paper proposes and studies a MAC scheduler, FIFO TBW, efficiently reducing the overhead due to beam switching delays.

Although one of the key issues for iSCSI is a security measure to access remote storage over IP networks, this is not necessarily established yet. iSCSI can employ IPsec that offers a function of strong encryption. However, the IPsec encryption processing degrades throughput of storage access and increases its CPU load. In addition, it is difficult to execute encryption processing efficiently, because IPsec layer is located in a lower-level. In this paper, we implemented a middleware system of executing encryption processing in the upper-layer for the communication using iSCSI securely and effectively. Moreover, we simulated the idea of optimization of encryption processing and evaluated its performance by running parallel processes in a long-latency network. As a result, optimization method of encryption processing is more efficient than that of IPsec in a long-latency network","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127150774","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 concept of capabilities, which requires that sources must acquire tokens prior to sending data, has been successfully applied on an end-to-end base to protect end systems. In this paper, we propose edge-based capabilities (EC), an architecture that prevents DDoS attacks and malware spread at the edge. EC introduces a novel network element termed gate. The gate controls IP packets that have previously been authenticated by an end-to-end mechanism. Authenticated traffic carries a session-specific tag in the IP header. Packets with valid tags are forwarded by the gate whereas traffic without or with wrong tags is treated with low priority or even dropped. EC achieves efficiency and scalability by defining a single lock against which tags are compared, removing the need to store per-flow information in the gate. Compared to related proposals, EC is easy to deploy as the gate can be added incrementally and EC requires only a single network element to be added at the edge","PeriodicalId":185969,"journal":{"name":"20th International Conference on Advanced Information Networking and Applications - Volume 1 (AINA'06)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-04-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130550549","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}
