Meng, Srihari Nelakuditi, Song Wang, Romit Roy Choudhury","doi":"10.1109/ICCNC.2015.7069442","DOIUrl":"https://doi.org/10.1109/ICCNC.2015.7069442","url":null,"abstract":"To assist drivers and prevent collisions, we propose a system called OmniView that extends driver's vision in all directions, using cameras of multiple collaborating smartphones in the surrounding vehicles. OmniView provides a driver with a traffic map about the relative positions of surrounding vehicles. Under OmniView, each vehicle detects other vehicles in its view, estimates their relative positions, and broadcasts its local map. Upon reception of a map from another vehicle, a vehicle updates its own map by fusing it with the received map. A key issue faced by OmniView is, how does a vehicle address another vehicle in its map? We propose that a vehicle's image itself could be treated as its address. However, if we include images in each map message, the communication overhead will be high. Towards that end, OmniView resolves a vehicle's image to a small unique ID. With this approach, we demonstrate that it is feasible to develop the OmniView system that produces a traffic map in real-time. Besides, through computer vision techniques and the collaboration between vehicles, OmniView could show the positions of surrounding vehicles with reasonable accuracy on the map. Such a traffic map, even without being displayed to the drivers, can act as the common substrate based on which various alerts can be triggered to avoid accidents.","PeriodicalId":219966,"journal":{"name":"2015 International Conference on Computing, Networking and Communications (ICNC)","volume":"79 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121902071","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 basestation in the system is equipped with multiple distributed antenna units (DAUs) spreading out at different locations in a service area, and they are connected to a central unit (CU) through high-throughput low-latency links such as optical fibers. In the downlink, signals for multiple users are first modulated and precoded at the CU, and are then forwarded to the DAUs, which broadcast the signals to all the users in the system. Each user extracts its own information with a linear filter. The beamforming precoder at the CU and the linear filters at the UEs are jointly designed to minimize the sum mean squared error (MSE) of all the users. The optimum designs are performed under two different power constraints: a constraint on the total power of all DAUs, and constraints on the power consumption of each DAU. Simulation results demonstrate that the performance of the proposed system improve with the number of DAUs and the number of UEs under both power constraints.","PeriodicalId":219966,"journal":{"name":"2015 International Conference on Computing, Networking and Communications (ICNC)","volume":"19 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129109042","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}

Pulmonary Artery Pressure (PAP) and Electrocardiogram (ECG/EKG) are selected as two preliminary physiological signals for this exercise as these two can help diagnose Cardio-Vascular Diseases (CVDs), the major silent killer of modern days. We use a Wireless Body Area Sensor Network to get the physiological data from a user's body and transmit them to a WBAN coordinator. The coordinator compresses received data from the body sensors, modulates it using bi-phase modulation scheme and sends it to a GSM module for remote transmission over existing cellular network. The GSM module receives the data and sends it to a remotely located tiny server for subsequent demodulation and reconstruction of the original signals. We explain details of different techniques used for data compression of this methodology and provide efficient transmission of data considering allowable range of perturbation in the information content in maintaining original characteristics. For the transmission of physiological data, we visualize to have a dedicated channel in upcoming fifth generation mobile technology, as more bandwidth for everybody is anticipated for services like data on demand, and would make 24×7 health-monitoring a reality in the near future. The novelty of our approach lies in the fact that it would enable online, round-the-clock health watch for the cellular system subscribers at very low power consumption by collaborating with the underlying sensor networks.","PeriodicalId":219966,"journal":{"name":"2015 International Conference on Computing, Networking and Communications (ICNC)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131733468","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}

Traditional channel model is a two-dimensional (2-D) channel model, where an elevation angle of each signal path is always assumed to be zero. While such an approach is acceptable for evaluating performance of systems with horizontally placed linear antenna arrays, modeling of elevation angles is necessary when evaluating a massive MIMO or FD-MIMO technology utilizing a 2-D antenna array. In 3GPP, a study has been finalized the details and the following key parameters are takes into account the wireless channel propagation in the elevation direction as well as the azimuth direction; height dependent pathloss generation, correlation of large scale parameters, and statistical distribution of elevation components. This paper discusses spatial channel characteristics of vertical domain as well as horizontal domain under different 2-D active array configuration. Impact on separate and full channel measurement and feedback for horizontal and vertical antennas also discusses. Furthermore, we recommend the design principle of codebook for 2-D active array which impacts on system performance.","PeriodicalId":219966,"journal":{"name":"2015 International Conference on Computing, Networking and Communications (ICNC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-03-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130230960","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}
