Abstract—This article considers the joint problem of packetscheduling and self-localization in an underwater acoustic sensornetwork with randomly distributed nodes. In terms of packetscheduling, our goal is to minimize the localization time, andto do so we consider two packet transmission schemes, namelya collision-free scheme (CFS), and a collision-tolerant scheme(CTS). The required localization time is formulated for…

Cloud based machine-to-machine (M2M) communications have emerged to achieve ubiquitous and autonomous data transportation for future daily life in the cyber-physical world. In light of the need of network characterizations, we analyze the connected M2M network in the machine swarm of geometric random graph topology, including degree distribution, network diameter, and average distance (i.e., hops).…

Shared Authority Based Privacy-PreservingAuthentication Protocol in Cloud ComputingHong Liu, Student Member, IEEE, Huansheng Ning, Senior Member, IEEE,Qingxu Xiong, Member, IEEE, and Laurence T. Yang, Member, IEEEAbstract—Cloud computing is an emerging data interactive paradigm to realize users’ data remotely stored in an online cloudserver. Cloud services provide great conveniences for the users to enjoy the on-demand…

Large organizations need rigorous security tools for analyzing potential vulnerabilities in their networks. However, managing large-scale networks with complex configurations is technically challenging. For example, organizational networks are usually dynamic with frequent configuration changes. These changes may include changes in the availability and connectivity of hosts and other devices, and services added to or removed…

—A data discovery and dissemination protocol for wireless sensor networks (WSNs) is responsible for updatingconfiguration parameters of, and distributing management commands to, the sensor nodes. All existing data discovery anddissemination protocols suffer from two drawbacks. First, they are based on the centralized approach; only the base station candistribute data items. Such an approach is not…

Abstract—We propose employing receiver cooperation in centralizedtopology control to improve energy efficiency as well asnetwork connectivity. The idea of transmitter cooperation hasbeen widely considered in topology control to improve networkconnectivity or energy efficiency. However, receiver cooperationhas not previously been considered in topology control. In particular,we show that we can improve both connectivity and energy efficiencyif…

Abstract—Social networks have been recently employed as asource of information for event detection, with particular referenceto road traffic congestion and car accidents. In this paper, wepresent a real-time monitoring system for traffic event detectionfrom Twitter stream analysis. The system fetches tweets fromTwitter according to several search criteria; processes tweets, byapplying text mining techniques; and finally…

REAL-TIME BIG DATA ANALYTICAL ARCHITECTURE FOR REMOTE SENSING APPLICATION ABSTRACT: In today’s era, there is a great deal added to real-time remote sensing Big Data than it seems at first, and extracting the useful information in an efficient manner leads a system toward a major computational challenges, such as to analyze, aggregate, and store, where…

Cloud storage such as Dropbox and Bitcasa is one of the most popular cloud services. Currently, with the prevalence of mobile cloud computing, users can even collaboratively edit the newest version of documents and synchronize the newest files on their smart mobile devices. A remarkable feature of current cloud storage is its virtually infinite storage.…

An initiative data prefetching scheme on the storage servers in distributed file systems for cloud computing. In this prefetching technique, the client machines are not substantially involved in the process of data prefetching, but the storage servers can directly prefetch the data after analyzing the history of disk I/O access events, and then send the…

With the increasing volume of images users share through social sites, maintaining privacy has become a major problem, as demonstrated by a recent wave of publicized incidents where users inadvertently shared personal information. In light of these incidents, the need of tools to help users control access to their shared content is apparent. Toward addressing…

Asthma is one of the most prevalent and costly chronic conditions in the United States which cannot be cured. However accurate and timely surveillance data could allow for timely and targeted interventions at the community or individual level. Current national asthma disease surveillance systems can have data availability lags of up to two weeks. Rapid…
