WMNs are increasingly being used in urban areas, metropolitan and municipal area networks for deployment of medical, transport, surveillance systems, etc. The good performance and operability of WMNs largely depends on placement of mesh routers nodes in the geographical area to achieve network connectivity and stability. Therefore, optimal placement of router nodes in WMNs is a main issue in deployment of WMNs. In this work we propose and evaluate local search methods for placement of mesh routers in WMNs with a two fold objective: maximizing the size of the giant component in the network and user coverage. Given a grid area where to distribute a given number of mesh router nodes, which can have different radio coverage, and a number of fixed clients a priori distributed in the given area, local search methods explore different local movements and incrementally improve the quality of the router nodes placement in terms of network connectivity and user coverage. We have experimentally evaluated the considered local search methods through a benchmark of generated instances varying from small to large size. In the instances, different distributions of mesh clients (Uniform, Normal, Exponential and Weibull) are considered aiming to evaluate the quality of achieved solutions for different client distributions. Although local search methods can be stuck in local optima, the experimental evaluation showed their good performance; local search methods could thus be applied as a first choice for optimizing network connectivity and user coverage in WMNs.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123956283","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}

On one hand, current available WSN management tools are either application specific, or platform specific, thus suffering from the lack of reusability in heterogeneous WSNs management environment. On the other hand, to develop a new WSN management system for heterogeneous WSNs from scratch is time consuming and may not be feasible. In this paper, motivated by such a challenge, we propose a novel WSN management system architecture targeted for heterogeneous WSNs (H-WSNMS). By introducing the concept of Virtual Command Set, H-WSNMS decouples management functions for specific WSN applications from the individual WSN platforms. Therefore, H-WSNMS facilitates the reuse of each individual WSN’s preliminary management command service as much as possible, and at the same time, presents to users a unified management interface across multiple WSNs. We demonstrate H-WSNMS architecture though design and implementation of a prototype system.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126672018","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}

There is a gap between today’s personal health records (PHRs) and what patients say they want and need from this electronic tool for managing their health information. Current barriers to PHR adoption among patients include cost, concerns that information is not protected or private, inconvenience, design shortcomings, and the inability to share information across organizations. We propose a novel architecture to bridge the gap based on Privacy Preserving Portable Health Record(P3HR), a device that incorporates a smart card into a USB flash drive which provides encrypted flash memory for secure mobile data storage. The salient features of the proposed Privacy Preserving Portable Health Record (P3HR) include: strong multifactor authentication using biometrics, public key infrastructure to verify the credentials of the applicants, SSL based authentication protocol suite for authorization and secure online updates, local backup to store patient data which ensures that the patient will have access to data in case of P3HR theft, lost device, hardware failure, software failure or a Computer virus.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"25 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114235611","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 majority of solutions proposed in the related literature to enable pervasive computing involves specific platforms and rigid architectures that are tightly bound with their target applications and services. This approach suffers from having to introduce new context-aware applications, thus limiting deployment in existing configurations. Nevertheless, the notion of pervasive computing calls for solutions to be tailored to user needs and not conversely. In this paper we introduce a framework that enables systems to become pervasive in a transparent manner, handling context monitoring and ubiquitous communications issues behind the scenes without affecting existing applications. Pervasive behavior is guaranteed by adapting systems based on monitored context information and guiding their re-configuration. We present the architecture of our proposed framework and discuss application scenarios, while considering evaluation aspects.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"53 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134018991","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 addition, we consider that non-verbal communication such as eye-to-eye contact and gesture play an important role. In order to realize realistic communication between remote places, the display of video image in remote site with the large-scale screen is effective. However, the video image by wide-area display using a projector and large screen is low-resolution, and sufficient presence is not obtained. In this paper, we have constructed tele-immersive environment with scalable tiled displays wall and study on the possibility of realistic communication. We have implemented an application to display high-resolution real video streaming, and realized to display by setting parallel transmission video images captured by 2 sets of cameras on tiled displays wall in remote place. Moreover, we have proposed the technique for automatic switching of transmission video in remote communication by the estimation of face direction from participant’s video with image-recognition technique in order to realize effective remote communication method between multi-point remote sites.","PeriodicalId":312802,"journal":{"name":"2009 International Conference on Network-Based Information Systems","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116963115","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}
