The system design must combine temporal requirements and considerable uncertainty, together with the ability to swiftly adapt to changing environmental conditions. This paper proposes a robust DRE model that does not require precise system parameters. A multivariable Hinfin controller is developed and provides utilisation and deadline guarantees in an unpredictable environment.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131443194","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}

Since a portable reader has own identifier and secret values associated with each tag, the portable reader can wirelessly communicate with the tag without help of central database. The RFID tag search can be useful to find a lost book among all RFID-tagged books in a library. However, the basic operation for RFID tag search has security and privacy problems. Secure search protocols to solve these problems were firstly discussed by Tan et al. Nonetheless, their protocols donpsilat perfectly solve an illegal tag tracking problem by a reuse attack of a search query and also have an illegal reader tracking problem by revealing the portable reader ID over an insecure channel. In this paper, we propose strong authentication protocol for secure RFID tag search without help of central database which utilizes a block cipher (AES-128) and a timestamp. Our protocol can search a particular tag efficiently, and preserve user privacy against all major attacks.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134557611","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 framework can be applied to address the communication issues in distributed and large-scaled sensor nodes in wireless sensor network application. There are two communication categories under consideration, i.e. intra-nodes and inter-nodes. Due to the potentially higher frequency in the signal propagation within the sensor node, the characteristics of the interconnect among various systems-on-chips cannot be described in the traditionally lumped R, L, C components. We adapt a distributed transmission line model to address such issues and possibly improve the reliability in the intra-nodes communication. Furthermore, based on the bandwidth requirements of each sensor node, the large-scaled senor network is proposed to be transformed into a maze diagram by a user defined threshold bandwidth, so that many existing approaches may be applied to determine the routing paths in the inter-nodes communication to improve the efficiency of the overall network.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130848901","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, increasing environmental constraints and performance requirements has spurred the development of tools to expedite deployment and minimize human intervention. This study extends previous work by the authors in network development and aims at the performance evaluation of applications operating in to-be-deployed networks. We prove that the determination of a ZigBee cluster tree over an underlying network is NP - hard and propose an algorithm for generating tree topology. Based on the proposed algorithm/technologies, an integrated development tool is developed. The capability of the tool is demonstrated by a case study of the system deployed in an office building.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133263234","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}

Several fault tolerance methods have been proposed to improve software reliability. These methods are based on either fault masking such as N-version programming or on fault detection such as in the recovery block method. The success of the recovery block method depends on a high quality of the effective acceptance test, which is sometimes very difficult to achieve. In this paper, we propose a hybrid fault tolerance method called recovery block with backup voting to improve the reliability of the normal recovery block in the case of a weak acceptance test. In the proposed method, a copy of the outcome of each version is stored in a cache memory as backup, and when the recovery block method fails to produce a correct output due to a weak acceptance test, the stored values are used as inputs to a voting method to produce the correct output. A Monte Carlo based simulation method is used to show the reliability improvement in the new proposed hybrid method as well as to show the decreased dependency of the new method on the quality of the acceptance test, which makes the new method more suitable for critical applications where the construction of an effective acceptance test is difficult.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"199 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134480700","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, traditional routing method for ad hoc network is not applicable in these situations. Current approaches for such networks are primarily based on redundant transmissions and single copy direct routing. However, they incur either high overhead due to excessive transmissions or long delays due to the incorrect path choices during forwarding. In this paper, we propose a direction based geographic routing scheme (DIG) for the intermittently connected network. Relying on the geographic location information, the packets are routed in a approximate ideal path to the destination, which significantly reduces the resource required in flooding-based algorithm and lead to decreased delay compared to the direct routing. Theoretical analyzes and simulations show that compared to the epidemic routing and direct routing, DIG provides nearly optimal delay with very low overhead.","PeriodicalId":430277,"journal":{"name":"2008 IEEE/IFIP International Conference on Embedded and Ubiquitous Computing","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124301848","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}
