In this way, this paper presents an intelligent sensor network which has been developed as a genetic fuzzy rule-based system. The objectives of the present work include: first, the design of the fuzzy rule-based sensor which incorporates a new inference engine specially designed for the intelligent sensor; and, second, the design of an evolutionary algorithm, which is adapted to the sensor and based on genetic algorithm, in order to evolve the knowledge of the system. The sensor network is composed of a computer and a set of sensors. Two possible implementations of the sensor are presented: the first one includes a fuzzy ruled-based sensor; the second implementation is based on a genetic fuzzy rule-based sensor. The sensor network can incorporate expert knowledge and evolve the knowledge bases. This intelligent sensor has been tested using a sensor which is based on an 8051 microcontroller, and an inference engine which has been designed for this sensor. The evolutionary algorithm has been tested using a simulated system. In conclusion, sensor networks can incorporate fuzzy rule-based system and evolutionary algorithms. The former group allows controlling a system by the knowledge base; the latter allows evolving knowledge bases in order to obtain new knowledge.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131300429","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}

A mixed sensor network is composed of a collection of static and mobile nodes that has sensing, computation, communication, and locomotion capabilities. Sensor mobility can be used to compensate for the lack of sensors and improve network coverage. This paper aims to describe an algorithm called Coin for mixed sensor network deployment in an unknown environment by using a small number of mobile sensors. It allows the network to achieve maximum coverage with minimum energy consumption. Our solution includes distributed schemes for: 1) determining the exact size of a coverage hole; 2) determining the number and locations of mobile sensors for covering a hole; 3) calling mobile sensors. Coin is an extension of CovEN algorithm, from [3]. Our distributed algorithm was implemented and simulated with NS-2 for performance evaluation. Simulation experiments show that our algorithm achieves the best results of coverage percentage.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123020913","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}

Autonomous sensors have a pulsed power consumption profile that causes high voltage drops in high impedance batteries. These voltage drops can make battery voltage go under the specified autonomous sensors' voltage supply range leading to a runtime reduction from the ideal case. In this paper battery-capacitor hybrids are proposed to reduce voltage drops in autonomous sensors. Analytical expressions for the voltage transient behavior and runtime extension under pulsed loads have been presented. Minimal capacitor's value for a determined voltage drop has been also obtained. Experimental results were carried out using two types of loads, a pulsed resistor and a real autonomous sensor. The runtime extensions achieved were 185 % and 169 % respectively. The ideal runtime (assuming no voltage drop) is nearly achieved in both cases, so almost all energy can be extracted.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123400726","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, protocols used in these networks must have little message exchange. This paper investigates the use of a knowledge based approach in analysing protocols and reducing their communication overhead. Such an approach enables us to examine what the nodes come to know through message exchange, and explore other ways of obtaining that knowledge. We apply this analysis to the popular directed diffusion protocol and show that it is possible to reduce message communication without compromising the protocol's performance.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"18 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116435026","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}

We present a micro service component model, entitled muSIC, that abstracts a sensor node as an entity that provides and uses services. This model is realized through the use of the muSIC runtime, a small and efficient message-oriented middleware (MOM) tailored for resource-constrained devices. The muSIC runtime can perform service-paging, a method of storing a service's state to flash memory and restoring it whenever the service is needed. Secondly, we provide a domain-specific language allowing applications to be expressed as a collection of services that run on top of the muSIC runtime and enables a multi-threaded programming model.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"107 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117251657","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 enables a much higher functionality of the mission compared to missions consisting of only a single satellite. The sensors present in each of the satellites in the formation enable sensing of photometric data from outer space. Using optical interferometry, the data from the individual satellite sensors is collected at a designated satellite which requires communication between the satellites, giving rise to a mobile sensor network in space. In order to gain most accurate data, the satellites must be kept in deterministic close relative positions, otherwise, the aggregated data is invalidated. Current control laws to establish reliable formations of satellites face many challenges especially for larger number of satellites. In this paper we present a distributed algorithm to scale current control laws to arbitrarily large satellite formations. This is achieved by a multi-level topology which is based on multiple weighted metrics andean cope even with the case of unpredictable metric values. We substantiate the performance of our algorithm by extensive simulations.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128888383","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}
