However, how to utilize UAVs in highly dynamic vehicular networks is not well studied yet challenging with limited UAV energy and storage capacity. In this paper, considering the vehicle mobility and content requests, we study the problem of proactive content placement, trajectory design, and content delivery for cache-enabled UAV. This problem is formulated as an optimization problem aiming at maximizing the overall network throughput improvement under the UAV energy constraint, which is non-convex and difficult to solve. To tackle this problem, we propose an efficient algorithm with a two-layered structure. First, given a content placement strategy, we devise a time-based graph decomposition method to jointly optimize the content delivery and trajectory design. Next, with the optimized content delivery and trajectory, we then leverage the particle swarm optimization (PSO) algorithm to further optimize the content placement. Numerical results show that the proposed scheme can efficiently solve the joint optimization problem and adapt to the dynamic network conditions.","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"191 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133362463","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 similarity between two genomic data records can be measured by the edit distance, which has significant applications in disease diagnosis and treatment. At the same time, due to the limited storage and computational resources at the local data owner, a typical solution for the edit distance computation is to outsource the genomic data to a powerful cloud. However, as the genomic data are sensitive and the cloud server is not fully trusted, there are privacy considerations during the edit distance computation. Apart from data privacy, efficiency also needs to be taken into consideration. In order to deal with the privacy and efficiency issues, in this paper, we propose an efficient and privacy-preserving edit distance computation scheme for a single data owner and single cloud server scenario. In specific, we first design an index technique to reduce the computational cost and communication overhead of the genomic data outsourcing, and introduce a fast edit distance computation technique to speed up the edit distance query. Then, we propose an efficient and privacy-preserving edit distance computation scheme by deploying the homomorphic encryption technique, which can well preserve the private information including genomic data records and edit distances. Besides, security analysis shows that the proposed scheme is privacy-preserving and performance evaluation validates the efficiency of the proposed scheme.","PeriodicalId":108635,"journal":{"name":"2019 11th International Conference on Wireless Communications and Signal Processing (WCSP)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123054842","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}
