Nevertheless, they are facing many problems in terms of resource storage capabilities and communications. So, Mobile Cloud Computing (MCC) has emerged as a new paradigm to overcome these limitations by integrating Cloud Computing into the mobile environment. Adopting this paradigm raises several challenges, particularly with regard to the performance and the correctness. On the one hand, attaining the optimal performance in MCC is not a trivial task due to the variety of often conflicting objectives. On the other hand, because of the complexity of the studied applications, their modeling is more prone to errors on the part of the designers. In this paper, we present a background on MCC including definition, advantages and applications. We also provide a survey of the proposed approaches in the literature focusing on the performance and the verification in MCC systems. Then, we show a comparative study of the existing solutions based on some criteria. Finally, we identify the main research issues and we suggest some directions for future research.","PeriodicalId":363800,"journal":{"name":"2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC)","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115696080","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}

GPS and WLAN are widely used technologies in recent smartphones for positioning and communication, respectively. However, both GPS and WLAN have serious energy consumption problem. For large scale tracking systems, where tracked people are supposed to move in groups, the continuous usage of the individual smartphones GPS and WiFi is not an energy efficient solution. In this work, we propose a cooperative approach that exploits the coexistence of of multiple communication interfaces (WiFi and Bluetooth) in recent smartphones where nearby smartphones are cooperatively grouped to form a cluster. A cluster is a network of one dynamically selected cluster head and regular members that communicate locally via Bluetooth. The cluster head is responsible of positioning and sharing positioning information with the rest of cluster members. It, also, acts as a gateway between its regular members and the server. We present a clustering approach according to the available energy and the energy cost. Our approach doesnt require any modifications in the recent smartphones equipment. We have formulated the clustering construction problem as a mixed integer program using GAMS. The proposed clustering approach has been evaluated via extensive simulation experiments and the obtained results have been compared with the optimal solution which show very close performance.","PeriodicalId":363800,"journal":{"name":"2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC)","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115702555","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}

To achieve full diversity and full data transmission rate, most researchers assumed perfect timing synchronization within the network. However, synchronisation in wireless cooperative relay networks is difficult in real environment due to the distributed nature of cooperative relay nodes. This paper first, deals with designing an efficient distributed space time block coding system to obtain double the full diversity and full data transmission rate for asynchronous cooperative relay networks. The second part deal with developing a low-level computational complexity sub-optimum detection scheme to overcome the imperfect synchronisation issues arising among the relay nodes. The computational complexity level depends only upon the constellation size. Analytical analysis and simulation results show that the double the full diversity with full data transmission rate are achieved. The proposed sub-optimum detection scheme can also effectively eliminate the intersymbol interference induced by the lack of synchronisation between the relay nodes at the destination node.","PeriodicalId":363800,"journal":{"name":"2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114672001","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}

Recently many commercial companies such as SpaceX, OneWeb plan to launch tens of thousands satellites which promotes the scale of satellite networks rapidly. While the scale of the satellite network is still small relatively compared with the terrestrial network. IP-routing ability in satellite network is becoming more and more important for ISTN. Suffering from high topology dynamics, long propagation delay, and onboard processing limitations on satellite networks, routing in ISTN faces many challenges worth analyzing in-depth.This paper builds an IP-based routing usability theoretical analytical model with calculable formula, which formulates different types of networks under a unified framework that accommodates various configurations and characteristics of multiple networks. Moreover, massive experiments based on real satellite motion data are designed and conducted to analyze the routing performance and challenges in ISTN deeply, combining various ground stations, satellite processing ability, number of satellites per orbit, etc. At last, with the analysis of routing usability for ISTN, some instructive conclusions are drawn. Although the number of routing nodes in satellite networks is relatively small compared with terrestrial networks, but the influence is big. With the network scale extending, high topology dynamics makes the IP-based routing performance of ISTN decrease dramatically. Routing usable time in one day period decreases from 23.36h to 2.99h when the number of satellites grows from 60 to 960. To keep routing usability, the number of satellites in space is not the more the better in ISTN. The scale of network and the onboard processing ability should do trade off.","PeriodicalId":363800,"journal":{"name":"2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121086030","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 aim of this technique is to calibrate the camera in order to collect more precise three dimensional data from the images to utilize for robot navigation, three dimensional reconstruction, biomedical, virtual reality and visual surveillance. In camera calibration one of the major issue is to search out the set of image parameters describing the mapping between three dimensional images reference coordinates and two-dimensional images reference coordinates. Currently, MATLAB toolbox and OpenCv are the most popular tools used by the researchers for camera calibration. We utilize the concept of deep learning to recognize the chessboard corners. Our presented technique is a convolutional neural network (CNN) trained on a huge number of chessboard images. The network is trained on different datasets: noisy and with high lens malformation images. The proposed scheme is more accurate than the conventional MATLAB algorithm technique. The presented technique is more accurate against the different sort of ruination present in the training set. Results reaffirmed the correctness and effectiveness of our proposed CNN technique.","PeriodicalId":363800,"journal":{"name":"2019 15th International Wireless Communications & Mobile Computing Conference (IWCMC)","volume":"126 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123665088","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}
