These sensor networks rely on the collective power of the separate devices as well as their computational and sensing capabilities to understand “global” environmental states through locally sampled information and local sensor interactions. Due to the locality of the sensor networks, that naturally arises due to the locality of their communications capabilities, a number of interesting connections exist between these networks and geometrical concepts and problems. In this paper we study two simple problems that pertain to the formation of low power and low interference communication patterns in fixed topology sensor networks. We study the problem of using multihop communication links instead of direct ones as well as the problem of forming a communication ring of sensor networks so as to reduce power consumption as well as interference from other nodes. Our focus is on the connection between sensor networks and geometrical concepts, rather than on practicality, so as to highlight their interrelationship.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131696311","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 continuous objects are quite different from the individual objects, such as people, animals, and vehicles in that they are continuously distributed across a region and usually occupy a large area. Accordingly, they are detected and sensed by many sensor nodes, and their sensing data are redundant and highly correlated. Hence, there needs any efficient scheme on collecting and aggregating locally their sensing data and generating the data report. The continuous objects also tend to diffuse, changes in shape, increases the size, even splits into multiple smaller continuous objects, or join together one continuous object. Accordingly, there also need any efficient scheme to manage efficiently the dynamic change of shape of the continuous objects. Therefore, we introduce Dynamic Rectangle Zone-based Collaboration Mechanism for detecting, tracking, and monitoring the continuous objects taking into account the dynamic change of their shape. The proposed mechanism constructs a dynamic rectangle zone included the area occupied by one continuous object. One center node in the zone collects and aggregates the sensing data from sensor nodes which detect the continuous object. The dynamic rectangle zone change newly according to dynamic change of the continuous object and the center node is also altered by another node to minimize the energy consumption for collecting the sensing data. Through simulation results, we also evaluate how environmental factors and control parameters affect the performance of the proposed mechanism.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122108790","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}

As ubiquitous networks will be realized in the near future, downloading large files quickly is also very important on various types of networks. However, if we use the parallel downloading method on dynamic networks, such as ad hoc networks, it will not work well because of high loss rate and delay. To address this issue, we adopt UDP as a transport layer protocol instead of TCP which guarantees perfect in-order delivery unnecessary for file downloading. In our previous paper, a prototype of the parallel downloading method using HTTP over UDP is developed, and it is confirmed that our method outperforms the traditional method which adopts TCP, especially when loss rate is high and delay is large. In this paper, the key feature of the parallel downloading method using HTTP/UDP is evaluated through simple theoretical estimation and some simulation experiments. As a result, it is confirmed that the large division number tends to yield short download time. The proposed method can be an attractive protocol to distribute large files on dynamic networks composed of wireless links.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123332239","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 such systems, the growing complexity of network structure result in need of increasing system reliability. Network reliability modeling and analysis need not only capture the complex dynamic process of network systems, but also need the facilities for applying, understanding and computing. The objective of this paper is to develop a suitable modeling and analysis framework to study the ad-hoc network reliability. Using the mutual transformations of reliability functions between the time-domain and the frequency-domain, we adopt frequency-domain analysis approach to model network reliability. The advantages of the proposed approach over the traditional time-domain approaches include capability to capture higher order moments of system characteristics, scalability to analyze reliability of complex network systems, efficiency in calculation and practicability in computer simulation, etc. Finally, numerical experiment results show the feasibility and efficacy of this approach.","PeriodicalId":342911,"journal":{"name":"2009 International Symposium on Autonomous Decentralized Systems","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132063369","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}
