Epidemic models have previously been employed by researchers to investigate the spreading dynamics of malware in the Internet. Most studies have generally ignored spatial deployment characteristics of nodes which are critical for a realistic analysis in wireless sensor networks. We consider random and localized attack strategies by malware that may be introduced by an adversary into a network with either completely random or clustered sensor deployment patterns. Results demonstrate that sensor networks face serious security threats, particularly in cases where sensors are deployed in clusters and when malware can carry out attacks to random targets. We recommend possible defense measures based on simple topology control that might slow down the spread of malware across the network and allow necessary measures to be taken for containing the spread when malware employs a localized attack strategy. Presented analysis has a significant impact on network security and defense industry since it provides an insight into potential threats to information and surveillance infrastructure consisting of wireless sensing devices.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"55 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":"130098803","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 particular, we present a grammar hierarchy for identifying \"cooking activity\" from low-level location measurements in an assisted living application.

Our experiments also demonstrate that substantial data interpretation can take place at the node level, allowing the network to operate on compact symbolic representations.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"76 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":"125492536","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}

While dense random deployments satisfy coverage and sensing requirements, constructing dense networks of sensor nodes poses economical constraints as well as the problem of redundancy. We provide an analytical framework for estimating the redundancy in a random deployment of nodes without the need of location information of nodes. We use an information theoretic approach to estimate the redundancy in a randomly deployed wireless sensor network and provide the Cramer-Rao bound on the error in estimating the redundancy in a wireless sensor network. We illustrate this redundancy estimation approach and calculate the bounds on the error in estimating the redundancy for a wireless sensor network with 1-redundancy. We also analytically show the interdependence between redundancy and network lifetime for random deployment.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"710 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":"116122893","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}

It is therefore extremely important to develop driver assistance systems that are centered on the driver. In this regards, various state of the art methods such as multi data sensor fusion techniques are applied on various types of physical sensors such as 3D cameras, ultrasounds, sonar and infrared. However, sensor data alone are always uncertain to some extent due to noise and possible sensor failures. Also the driver, alone, is uncertain because of several parameters such as tiredness and drowsiness. In this paper we show the importance of providing a novel hybrid data fusion algorithm using both physical sensors and the driver's senses, as a supplementary data fusion system while driving. In this article, we use a fuzzy logic controller to manage and fuse the gathered data so take better action than individual driver or sensor fusion.","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":"131199258","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 beacon enabled mode QoS is supported by using guaranteed time slots(GTS). However maximum number of GTS node cannot exceed seven, and the number is not sufficient for wireless sensor network which have high node density. In this paper, we present QoS support mechanism in beacon enabled mode using CSMA/CA back-off time. Our algorithm have compatibility with IEEE 802.15.4 Standard, which means that there is no need to change hardware to support QoS on existing network.

The antennas are based on the well- known Yagi-Uda antenna and the principal difference between them is on the printed dipole design; in only one face of the substrate or in both faces. The design has been performed by using an in house developed code based on FDTD algorithm. In the design process, we have focused on the optimization of the bandwidth and the directivity. Finally, some prototypes with different number of dipoles have been fabricated and measured. The good agreement between simulated and experimental results demonstrates the validity of the simulations. The radiation parameters show the potentiality of these antennas for increasing the distance of communication in wireless networks.","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":"125112173","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}

Wireless sensor networks (WSN) appear as a key enabler for this sort of functionality, being able to obtain the required information and transmitting it to concentrator nodes. However, there are different sensor platforms, usually not compatible among them and, under specific conditions, considering the advantages of each one, it might be sensible using more than one of them within the same application. This paper describes the design and implementation of a framework for WSN (WSN adaptation framework, WAF), which offers a generic API able to manage subjacent heterogeneous sensor platforms, thus allowing a homogenous usage of their functionalities, especially from the service developer perspective, who does not longer need to worry about the primitives specific to the different platforms. Furthermore, the paper shows two illustrative examples on the usage of the generic API.","PeriodicalId":161788,"journal":{"name":"2007 International Conference on Sensor Technologies and Applications (SENSORCOMM 2007)","volume":"63 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":"116240610","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 first approach uses a training session and the position is based on Neuronal Networks using the training measurements. The second approach uses triangulation model with some fixed access points, but taking into account wall losses.
