Recently, the internet-of-things (IoT) has emerged as a new paradigm with an ever-increasing number of things to be connected to the internet. Different from the conventional paradigms, in the IoT the data computing scheme is needed to efficiently collect and offer data to provide sensing service. However, the existing data computing schemes are unfriendly which lack the integrated and incentive consideration to reduce the cost of data collection and encourage more participants for cooperation. Therefore, in this paper we propose a utility-based data computing scheme which allows vehicles to collect mobile data in the urban area, in order to provide sensing service in the IoT. First, we present an integrated architecture by introducing roadside buffers where each buffer can have a sink node to collect sensor data from vehicles. Next, by considering both the time cost and power cost during the data collection, we make the analysis of utilities in data computing process. Then, with a bargaining game to model the interaction among participants, a utility based data computing scheme is proposed with incentives where the optimal price can be determined for sensing service. Finally, extensive simulation experiments prove that the proposed scheme can efficiently improve the sensing service in IoT with a low cost.

The data computing process is utilized in various areas such as autonomous driving. Autonomous vehicles are intended to detect and track nearby moving objects avoiding collisions and to navigate in complex situations, such as heavy traffic and dense pedestrian areas. Therefore, object tracking is the core technology in the environment perception systems of autonomous vehicles and requires the monitoring of surrounding objects and the prediction of the moving states of objects in real time. In this paper, a multiple object tracking method based on light detection and ranging (LiDAR) data is proposed by using a Kalman filter and data computing process. We suppose that the movements of the tracking objects are captured consecutively as frames;thus, model-based detection and tracking of dynamic objects are possible. A Kalman filter is applied for predicting posterior state of tracking object based on anterior state of the tracking object. State denotes the positions, shapes, and sizes of objects. By computing the likelihood probability between predicted tracking objects and clusters which registered from tracking objects, the data association process of the tracking objects can be generated. Experimental results showed enhanced object tracking performance in a dynamic environment. The average matching probability of the tracking object was greater than 92.9%.

Fault-tolerance is a significant property for distributed and parallel computing systems. An emerging trend of Big data computing is to combine MPI and MapReduce technologies in a single framework. The distinctive state model in this kind of frameworks brings challenges to designing an efficient and transparent fault-tolerance mechanism. In this paper, a state model analysis method is proposed for uniformly modeling independent MPI, MapReduce and MPI-based MapReduce data computing frameworks. Based on this analysis, a library-level fault-tolerance mechanism with global persistent state model is proposed;a data-staging and routine-sharing based checkpoint approach is designed within this mechanism. The proposed mechanism has been implemented in dataMPI, a communication library supporting MPI-based MapReduce data computing applications. The experiments show that it can transparently enable fault-tolerance for applications. Taking TeraSort as an example, it introduces only 6.8% time overhead and 11% space overhead. For a failure-resume execution, it has a 10%-32% performance advantage compared with the naive checkpoint solutions based on local or parallel storages. The proposed mechanism also provides superior performance and resource utilization compared with Hadoop for both fault-free and failure-resume executions.

Since the release of blockchain technology back in 2008, a huge number of blockchain-based systems have been developed. As of Sep'22, there are at least 1, 000 blockchain systems ready to be used, with at least four types of networks: public, private, hybrid, and consortium. With the many options you can choose from, a valid question arises: How can we choose a system that fits best with our needs? The purpose of Blockchain Pedia is to help users make the best decision in choosing the right blockchain system, giving the possibility to see the differences between multiple options. The application is designed for anyone who wants to build a project based on blockchain technology, giving recommendations based on the needs of the developer. © 2023 The Authors.

The context of smart cities and cloud computing is essential to understanding the broader landscape in which security challenges and privacy perspectives play pivotal roles in enhancing the quality of life for the residents in smart cities. Smart cities use information and communication technologies (ICT) to optimize resource efficiency. They leverage data, sensors, and connectivity to improve various aspects of urban living, including transportation, energy usage, public services, and sustainability. Cloud computing is an integral part of the infrastructure of smart cities that enables the collection, storage, analysis, and sharing of data and services. This research paper indicates many factors and challenges in the development of cloud-enabled smart city areas and provides potential recommendations. A guideline for future studies on this research topic has also been provided to serve the comparative analysis of the various findings and results. © 2023 IEEE.

For passive bistatic radar (PBR), it is convenient to use software method to realise the signal processing. However, because of the huge amount of data computing, it is difficult to achieve the real-time signal processing by software method only with server that uses CPU for calculation. To solve the problem, the PBR signal processing method with multi-CPUs based on pipeline processing is studied. The key point of the method is to improve the parallelism of the signal processing algorithm and to use all the CPU cores efficiently for parallel computing. The whole PBR signal processing is divided into several steps, such as clutter cancellation, correlation processing, CFAR detection and so on, and each step employs different CPU resources that contain many cores. The data processed in each steps is also divided into several pieces to fully use all the CPU cores. At last, the signal processing in software for digital television terrestrial broadcasting (DTTB) signal is achieved based on the method. The experiment is carried out to verify the method. In the experiment, the whole signal processing time for DTTB signal is much less than the time of signal to be processed, and the signal processing output is continuous.

Ocean observation plays an essential role in ocean exploration. Ocean science is entering into big data era with the exponentially growth of information technology and advances in ocean observatories. Ocean observatories are collections of platforms capable of carrying sensors to sample the ocean over appropriate spatiotemporal scales. data collected by these platforms help answer a range of fundamental and applied research questions. Many countries are spending considerable amount of resources on ocean observing programs for various purposes. Given the huge volume, diverse types, sustained measurement, and potential uses of ocean observing data, it is a typical kind of big data, namely marine big data. The traditional data-centric infrastructure is insufficient to deal with new challenges arising in ocean science. New distributed, large-scale modern infrastructure backbone is urgently required. This paper discusses some possible strategies to solve marine big data challenges in the phases of data storage, data computing, and analysis. Some applications in physics, chemistry, geology, and biology illustrate the significant uses of marine big data. Finally, we highlight some challenges and key issues in marine big data.

Developing IoT, data computing and Cloud computing software requires different programming skills and different programming languages. This cause a problem for many companies and researchers that need to hires many programmers to develop a complete solution. The problem is related directly to the financial cost and the development time which are very important factors to many research projects. In this paper we present and propose the PWCT visual programming tool for developing IoT, data computing and Cloud computing Applications and Systems without writing textual code directly. Using PWCT increase productivity and provide researchers with one visual programming tool to develop different solutions.
