These networks are made of tiny nodes which are becoming future of many applications where sensor networks are deployed in hostile environments. The deployment nature where sensor networks are prone to physical interaction with environment and resource limitations raises some serious questions to secure these nodes against adversaries. The traditional security measures are not enough to overcome these weaknesses. To address the special security needs of tiny sensor nodes and sensor networks as a whole we introduce a security framework. In our framework we emphasize on three areas: (1) cluster formation (2) secure key management scheme, and (3) a secure routing algorithm. Our security analysis shows that the framework presented in this paper meets the unique security needs of sensor networks.","PeriodicalId":264517,"journal":{"name":"Proceedings of the 2006 IEEE Sensors Applications Symposium, 2006.","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122044877","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}

Currently, there is no UML model for CEDS (component electronic datasheets). This paper describes our seminal work for the development of a CEDS prototype. We define a partial UML model for CEDS and proceed to implement it in Gensym G2 software. An object oriented approach towards CEDS will allow development engineers shorter development times and operations and ground staff ease of maintenance. device. We attempt to define Component Electronic Datasheet (CEDS) prototypes for ISHMs. By allowing CEDS to become an entity within the ISHM framework, standards could be created to help understand the components involved in an ISHM. For our problem, we consider five objects. They include an accumulator, hydraulic main pump, indicating thermometer, air bleed valve and pressure line filter. In this paper, we propose an object oriented approach to the development of CEDS for the above mentioned five objects.

The requirements and processes to implement ISHM capability are unique in that a credible capability is initially implemented at a low level, and it evolves to achieve higher levels by incremental augmentation.

The approach will describe core ingredients (e.g. technologies, architectures, etc.) and when and how ISHM capabilities may be implemented. A specific architecture/taxonomy/ontology will be described, as well as a prototype software environment that supports development of ISHM capability.

{"title":"Liquid hydrogen sensor considerations for space exploration","authors":"M. Moran","doi":"10.1109/SAS.2006.1634265","DOIUrl":"https://doi.org/10.1109/SAS.2006.1634265","url":null,"abstract":"Abstract The on-orbit management of liquid hydrogen planned for the return to the moon will introduce new considerations not encountered in previous missions. This paper identifies critical liquid hydrogen sensing needs from the perspective of reliable on-orbit cryogenic fluid management, and contrasts the fun-damental differences in fluid and thermodynamic behavior for ground-based versus on-orbit conditions. Opportunities for advanced sensor development and implementation are explored in the context of critical Exploration Architecture operations such as on-orbit storage, docking, and trans-lunar injection burn. Key sensing needs relative to these operations are also examined, including: liquid/vapor detection, thermo-dynamic condition monitoring, mass gauging, and leak detec-tion. Finally, operational aspects of an integrated system health management approach are discussed to highlight the potential impact on mission success. Introduction The recent unveiling of NASA’s Exploration Architecture reveals a scenario that will mark a first in space operations: the extended storage and handling of large quantities of liquid hydrogen on-orbit. The closest precedent has been much shorter coast periods of Centaur upper stages for some mis-sions (e.g., 33 min for the Mars Reconnaissance Orbiter (ref. 1). The on-orbit management of liquid hydrogen planned for the return to the moon will introduce new and critical con-siderations not encountered in previous missions. Figure 1 provides a conceptual operations timeline for the earth-to-orbit phase of the mission (refs. 2 and 3). First, the Cargo Launch Vehicle (CaLV) delivers the Lunar Surface Access Module (LSAM) and the Earth Departure Stage (EDS) to low earth orbit (LEO). The Crew Exploration Vehicle (CEV) is delivered to LEO next on a separate Crew Launch Vehicle (CLV). Finally, the CEV, LSAM, and EDS rendez-vous on-orbit and begin the trans-lunar injection burn. The elapsed time between the CaLV lift-off and the dock-ing of the CEV, LSAM, and EDS could be from hours to days depending on a variety of factors including mission planning, pre-launch anomalies, and weather conditions. During this period the liquid hydrogen/liquid oxygen departure stage is subjected to a low-gravity orbital environment that poses unique challenges for liquid hydrogen system management. Similar low-gravity cryogenic fluid management challenges result from the operational need for a fueled CEV/SM (service module) to remain at the International Space Station (ISS) for periods up to six months, with the capability to leave the ISS within minutes (ref. 4). From a commercial space perspective, NASA Administra-tor Michael Griffin has consistently stated his interest in pro-moting private sector development of space transportation elements such as earth-orbiting fuel depots (ref. 5). These depots could replenish space vehicles bound to the moon or Mars with liquid hydrogen and other required propellants that typically make up half t","PeriodicalId":264517,"journal":{"name":"Proceedings of the 2006 IEEE Sensors Applications Symposium, 2006.","volume":"39 4","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-06-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114113502","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 study carried out respiratory rate measurements using a sensor belt with a high-resolution accelerometer (capacitive MEMS) and an EMFit (electret film) pressure sensor. Results obtained from tests on 10 subjects showed that both sensors are feasible for respiratory rate measurement; the reliability of the MEMS was 90%, while that of the EMFit was 90- 100%.
