Mobile Ad Hoc network is rapidly developing research area, one of the open question in this area is secure data inside the network. Encryption algorithms play a main role in information security systems. On the other side, those algorithms consume a significant amount of computing resources such as CPU time, memory, and battery power. This paper provides evaluation of three of the common encryption...
Nowadays Spark has been widely adopted as a sharp blade in solving big data problems by pipelining tasks of jobs on each node of cluster. In order to improve cluster resource utilization, lots of Spark performance-tuning advices have been proposed both by Spark and researchers. However, we notice that most of these advices focus tuning configuration items in isolation without considering job characteristics...
With the prevalence of cloud storage, more and more users store their files in cloud storage. There are a large number of duplicate files in the cloud storage, which makes file deduplication important for saving the storage space. After analyzing the features of cloud files, this paper proposes a new file deduplication method based on differential bloom filter. Besides utilizing application aw are...
The emergence of TV two-dimensional code not only makes the traditional TV media and new media to connect more closely, but also achieves the “mobile - television - network” direct interaction, greatly promoting the trend of media convergence. This paper, basing on the two-dimensional code generation techniques - PHP QR code, uses the MVC framework and Open API technology to design and complete the...
The existing opinion mining method based on adverbs about Chinese comments has lower precision rate and recall rate. For this problem, this paper redefined the narrow opinion word, and proposed an improved algorithm of Chinese comments opinion mining based on adverbs: In the extraction process of the feature words and opinion words based on adverbs increased conjunctions and negative words judgment;...
