Since these missions are deployed in environments where replenishing resources, such as smart phone batteries, is hard, it is necessary to maximize the lifespan of the mission while also maintaining its real-time quality of service (QoS) requirements. To address these requirements, this paper presents a deployment framework called Smart Deploy, which integrates bin packing heuristics with evolutionary algorithms to produce near-optimal deployment solutions that are computationally inexpensive to compute for maximizing the lifespan of smart phone-based mission critical applications. The paper evaluates the merits of deployments produced by Smart Deploy for a search-and-rescue mission comprising a heterogeneous mix of smart phones by integrating a worst-fit bin packing heuristic with particle swarm optimization and genetic algorithm. Results of our experiments indicate that the missions deployed using Smart Deploy have a lifespan that is 20% to 162% greater than those deployed using just the bin packing heuristic or evolutionary algorithms. Although Smart Deploy is slightly slower than the other algorithms, the slower speed is acceptable for offline computations of deployment.","PeriodicalId":431231,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116893343","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}

These devices are typically connected to backend systems via the mobile phone network with their corresponding data services. Today's network protocols are optimized for reliable transfer of voice traffic, however, available bandwidth and latency for data traffic may vary significantly with location and motion speed of a mobile device. Within this paper, we report on experiences from our eHealth project \"Fontane\", where real-time streaming data from electrocardiographic devices has to be transferred from patient's home to doctors at a telemedicine center. In order to deal with varying bandwidth and transmission characteristics on the radio link, we propose a predictive model that allows for pro-active application reconfiguration in order to adapt to anticipated bandwidth variations. Our model is being integrated into a self-adaptive middleware for mobile communication. We present our initial study on network bandwidth estimation, which reveals that the measurement of the available bandwidth using standard end-to-end methods does not work well for mobile cellular networks due to a fairly high number of interference factors in wireless environments. We therefore propose a multilevel forecast model to better predict the network bandwidth of the immediate future.","PeriodicalId":431231,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123118673","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}

However, robot application developers using robot components must invest non-trivial amount of time and effort applying fault tolerance techniques into their robot applications. Despite the need for a common, framework-level fault management, the majority of existing robot software frameworks has failed to provide systematic fault management features. In this paper, we propose a fault management method to detect, diagnose, isolate and recover faults based on the OPRoS software framework. The proposed method provides a collective, framework-level management for commonly encountered robot software faults, thereby reducing the application developers' efforts while enhancing the robot system reliability. To verify the effectiveness of the proposed approach, we have implemented a prototype reconnaissance robot using OPRoS components and injected different types of faults. The results of the experiments have shown that our approach effectively detects, diagnoses, and recovers component faults using the software framework.","PeriodicalId":431231,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130236846","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 adoption of standards, such as IP multicast, has facilitated this. IP multicast also enables recovering some of the advantages of the broadcast medium when using IP in tactical environments. However, the traditional Quality of Service (QoS) approaches for IP multicast fall short of satisfying the stringent QoS requirements in tactical environments, which typically have single-hop, line-of-sight connections. The reasons for this are (1) QoS in IP networks, frequently based on Differentiated Services, relies on routers to enforce the priorities which typically don't exist in tactical networks, and (2) QoS for tactical users needs to be enforced at the information level, not the packet level where the loss or delay of a single packet can invalidate an entire object of information. We present strategies for QoS management for IP multicast in tactical environments that provides information and user-level QoS and addresses the specific challenges of tactical radios (such as the lack of reliable capacity information). We present our solutions in the context of a tactical information broker that provides beyond line-of-sight information management in a theater of operations.","PeriodicalId":431231,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing","volume":"127 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121492884","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}

Traditionally, the WCET of a program is estimated assuming availability of the program's binary which is disassembled to reconstruct the program, and in some cases its source code to derive useful high-level execution information. However, in certain scenarios the program's owner requires that the binary of the program not be reverse-engineered to protect intellectual property, and in extreme situations, the program's binary is not available for the analysis, in which case it is substituted by program-execution traces. In this paper we show that we can obtain WCET estimates for programs based on runtime-generated or owner-provided time-stamped execution traces and without the need to access the source code or reverse-engineer the binaries of the programs. We show that we can provide very accurate WCET estimations using both integer linear programming (ILP) and constraint logic programming (CLP). Our method generates safe and tight WCET estimations for all the benchmarks used in the evaluation.","PeriodicalId":431231,"journal":{"name":"2011 14th IEEE International Symposium on Object/Component/Service-Oriented Real-Time Distributed Computing","volume":"201 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121896996","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}
