Our work is motivated by the fact that when small parts of networks incur emergencies according to a heavy-tailed distribution, the structure of the network under resource constraints results in the entire system behaving in a heavy-tailed manner. To address this, metrics other than average-case need to be used. We achieve robust location strategies by including risk metrics that account for tail behavior and not average performance alone. Because of the exponentially large solution space for locating K ambulances in N locations on the network, our approach is based on an efficient algorithm that allows for optimizing based on these risk metrics. We show that optimizing based on risk measures can account for spatiotemporal patterns and prevent the extent of delay cascades that are typically seen in heavy-tailed arrival distributions. From our computational results based on data from a large Asian city, we show that planning with some robustness metrics as targets leads to solutions that perform well in heavy-tailed demand scenarios.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129303792","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 service providers require access to a wide range of personal data, which are often sensitive. In this paper, we propose a lightweight privacy-preserving trust model based on the observation that a large class of applications can be provisioned based on simple threshold detection. The key issue we address in this work is how to minimize privacy loss in the presence of untrusted service providers so that providers are prevented from disclosing information to third parties for secondary uses. Our work can be considered as a lightweight approach to functional encryption (FE) for privacy-preservation. The main algorithm in the proposed model is a uniformization scheme that uses a combination of sensor aliases to hide the identity of the sensing source and per-function initialization vector to reveal information only to relevant service providers. We have implemented a prototype of the proposed scheme on TelsoB, thereby demonstrating the feasibility of the proposed scheme on resource-constrained devices.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116262880","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}

Managing these signal control systems at their optimal performance has been an important research focus in traffic engineering. However, various optimization techniques and algorithms developed for adaptive signal control are less effective for real-time implementation in non-lane following heterogeneous road traffic due to the following possible reasons: erroneous demand estimation, time-expensive computations, or uncertainty of getting optimal solutions. Rather, these models work efficiently for homogeneous lane-following traffic where demand predictions are accurate. This work proposes an optimization model that minimizes the total average control delay and finds the optimal green times without any explicit demand prediction for heterogeneous non-lane following road traffic. The proposed solution approach finds the optimal green times and the cycle time in real-time, and the obtained solutions are adaptive to traffic fluctuations. Simulation results show significant reduction in the average control delay and average queue length as compared to vehicle actuated (VA) system and a real-time reinforcement learning model (RLM) for non-lane following heterogeneous traffic.","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"14 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124275555","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}

Developments in computing, signal processing and communication technologies have resulted in new diagnostic instruments with better precision and connectivity with computing machines, communication gadgets and databases. However, many of these technical marvels are young by age and not yet available to all potential users at affordable cost. Among the various vital biomedical signals that can be collected non-invasively, ECG, PPG, SpO2 and PCG collected simultaneously, can help in examining electrical (ECG) and mechanical (PCG) functioning of heart, efficiency of lungs (SpO2) and condition of arteries (PPG). This promises to give a composite overview of the whole cardiovascular system non-invasively. We propose to develop a portable multi-parameter, non-invasive biomedical signal acquisition system (which can monitor, store and communicate the above mentioned four biomedical signals) for regular telemonitoring of patients especially with cardiovascular complaints. The device will be easy to use and can be operated by a paramedical staff with minimal training. It will be low-cost, so that a large population can be covered using multiple portable units. The gathered physiological data can be sent to the monitoring station and depending on the condition of the patient, further instructions can be issued from there. We also propose to analyze the different signals gathered and find correlation present in them which can lead to a better understanding of the whole cardiovascular system and assist doctors in early diagnosis of crucial symptoms. As an initial step towards that, Blood pressure (BP) and Heart rate (HR) is monitored using the gathered ECG and PPG signals from the device. The reliability of the device for BP and HR monitoring is estimated by comparing it with a clinically proven professional automatic digital BP monitor (OMRON HBP1300).","PeriodicalId":185861,"journal":{"name":"2016 8th International Conference on Communication Systems and Networks (COMSNETS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131392350","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}
