Reliable VANETbased services require dynamic resource management due to limited and often fluctuating network connectivity of VANETs that stem from the wireless and mobile nature of vehicleto-vehicle (V2V) communications. To address these needs, a collaboration with Road-Side Units (RSU) have been proposed to complement V2V communication by providing event and data brokering capability in the form of Vehicle-to-Infrastructure (V2I) communications. Deploying RSUs involves upfront investment and maintenance costs, and hence solutions are needed that maximize the benefit of RSUs by placing them effectively in accordance to existing and projected traffic density, and the types of services planned for VANETs. To address these challenges, this paper proposes a novel Voronoi diagram-based algorithm for the effective placement of RSUs using packet delay and loss as a criteria. This approach has two-fold advantages: a significant reduction in the number of RSUs required to cover a geographic region, and increase in the logical coverage area of each RSU irrespective of the dynamic vehicular traffic conditions thereby improving reliability of communications. This algorithm has been evaluated in the context of a road network and traffic conditions for an urban area. When compared with other baseline placement algorithms, communication reliability stemming from our Voronoi diagram-based placement algorithm results in less packet delay and lesser packet loss both of which are important to realize the different VANET-based services.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116598622","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}

Regardless of the type of information, users may collaborate amongst their peers, deliver company organizational updates to a large group of people, and document research. Researchers at the Air Force Research Labs Discovery Lab, a year round research and STEM internship program, have set precedence for using the virtual world for these applications. The Discovery Lab focuses research on engineering problems that are relevant to the United States Air Force, and has two major components: the physical Discovery Lab, and the Virtual Discovery Center. The Virtual Discovery Center uses the open source 3D application server, called OpenSimulator, and has acted as a capstone for the organization. The Virtual Discovery Center is home for much of the Discovery Lab's collaboration, innovation, and research documentation. Researchers may meet and discuss via voice and text, and may share graphics to report project accomplishments. Since at times the Discovery Lab hosts more than one hundred researchers and collaborators, the virtual world serves as a medium for delivering important programmatic updates, as well as holding virtual group meetings. The Virtual Discovery Center is additionally used for research, professional training, and data visualization by utilizing the virtual worlds unique 3D object building and scripting techniques. The methods used by the Discovery Lab are proposed as an effective system for provoking collaboration and the exchange of information.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114848186","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 motivating scenario is an emergency evacuation by a transport convoy of unmanned ground vehicles (UGVs) that have to traverse, in shortest time, an unknown terrain. In the experiments the operator commands, in minimal time, a group of rovers through a maze. The efficiency of performing such tasks depends on both, the levels of robots' autonomy, and the ability of the operator to command and control the team. The paper extends the classic framework of levels of autonomy (LOA), to levels/hierarchy of autonomy characteristic of Groups (G-LOA), and uses it to determine new strategies for control. An UGVoriented command language (UGVL) is defined, and a mapping is performed from the human-friendly gesture-based HMRI into the UGVL. The UGVL is used to control a team of 3 robots, exploring the efficiency of different G-LOA; specifically, by (a) controlling each robot individually through the maze, (b) controlling a leader and cloning its controls to followers, and (c) controlling the entire group. Not surprisingly, commands at increased G-LOA lead to a faster traverse, yet a number of aspects are worth discussing in this context.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128120700","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 designed to handle the challenges that arise in hybrid distributed infrastructures. It does so by implementing a number of software components that select and manage storage, computation and network resources in order to meet the Quality of Service levels desired by the user. One advantage our our system that has facilitated its adoption by CineGrid, an interdisciplinary community focused on the digital cinema domain, is that it shields the end user from the details of the IT infrastructure and allows users from different member organizations to use any resource available in the community. The dynamic nature of the infrastructure makes it susceptible to bottlenecks and our prototype focuses on determining I/O hotspots. At the core of the system lie resource descriptions based on semantic web ontologies that provide information about the existing resources. By using them, the resource selection process is optimized and in line with the application's estimated demands. In this work we focus on the I/O performance as a bottleneck type. We show how HybridFlow can be used in the typical scenario of a video processing pipeline to identify bottlenecks and work towards achieving the desired QoS levels while keeping resource utilization optimal.","PeriodicalId":256633,"journal":{"name":"2013 International Conference on Collaboration Technologies and Systems (CTS)","volume":"92 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-05-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124653899","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}
