Cooperative Driving

With the rapid development of information and communication technology, future intelligent transportation systems will exhibit a trend of cooperative driving of connected vehicles. Platooning is an important application technique for cooperative driving. Herein, optimized car-following models for platoon control based on intervehicle communication technology are proposed. On the basis of existing indicators, a series of evaluation methods for platoon safety, stability, and energy consumption is constructed. Numerical simulations are used to compare the effects of three traditional models and their optimized counterparts on the car-following process. Moreover, the influence of homogenous and heterogeneous attributes on the platoon is analyzed. The optimized model proposed in this paper can improve the stability and safety of vehicle following and reduce the total fuel consumption. The simulation results show that a homogenous platoon can enhance the overall stability of the platoon and that the desired safety margin (DSM) model is better suited for heterogeneous platoon control than the other two models. This paper provides a practical method for the design and systematic evaluation of a platoon control strategy, which is one of the key focuses in the connected and autonomous vehicle industry.

Because of rapid development of wireless communication technology, there is an increasing adoption of mobile advertising, such as location based advertising (LBA). To what extent can LBA improve advertising effectiveness is an important topic in the field of wireless communication technology research. Most researches quantify long term impacts of advertisings by VAR (Vector Autoregressive) model. However, compared to VAR model, VECM (Vector Error Correction Model) is a better method in that it allows one to estimate both a long-term equilibrium relationship and a short-term dynamic error correction process. In this study, we employ VECM to explore LBA’s (Location Based Advertising) and PUA’s (Pop-up Advertising) sales impact in both short and long terms. The developed VECM reveals that LBA’s sales impact is about more than2 times as big as PUA’s in short dynamic term and nearly 6 times bigger than PUA’s in long equilibrium term. These findings add to advertising and VECM literatures. These results can give managers more confident to apply wireless communication technology to advertising.

Definition Of

With the rapid development and application of medical sensor networks, the security has become a big challenge to be resolved. Trust mechanism as a method of “soft security” has been proposed to guarantee the network security. Trust models to compute the trustworthiness of single node and each path are constructed, respectively, in this paper. For the trust relationship between nodes, trust value in every interval is quantified based on Bayesian inference. A node estimates the parameters of prior distribution by using the collected recommendation information and obtains the posterior distribution combined with direct interactions. Further, the weights of trust values are allocated through using the ordered weighted vector twice and overall trust degree is represented. With the associated properties of Tsallis entropy, the definition of path Tsallis entropy is put forward, which can comprehensively measure the uncertainty of each path. Then a method to calculate the credibility of each path is derived. The simulation results show that the proposed models can correctly reflect the dynamic of node behavior, quickly identify the malicious attacks, and effectively avoid such path containing low-trust nodes so as to enhance the robustness.

Over the years, the rise of digital economy has confused countries in their efforts to tax foreign companies without physically presence within their jurisdiction. One of the potential tax revenues that have not been optimally digging comes from the digital sector. The digital economy sector has enormous potential along with the rapid development of information and communication technology, especially the internet. This digital economy market is dominated by internet-based services commonly called Over The Top (OTT) services and is filled with global content owned by foreign companies. This article argues the provisions of taxation for foreign OTT lending providers in England, Australia, India, and Japan. This research used a qualitative non-case study approach. This study outlines the strengths and weaknesses of each alternative.

With the rapid development of communication technology, modern communication technology has been widely penetrated into modern national defense, science and technology, people's life and other fields, and has become a means to provide high-quality and seamless information communication between people and machines. With the rapid development of computer technology and the Internet, the traditional program-controlled switching technology has come to an end, and the soft-switch network based on IP technology and packet switching has gradually replaced the program-controlled switching network based on circuit switching and become the mainstream of today's communication network world. The rapid development of VOIP telephony reduces the cost of domestic and international long-distance telephony, benefiting consumers. Digital mobile communication expands channel capacity, improves service quality and promotes the rapid development of this industry. Based on the secondary development of the open source FreeSWITCH software, this paper develops a VOIP voice system based on IP technology to meet different user needs intelligently [1].

With IoT era, development raises several significant research questions in terms of system architecture, design and improvement. For example; the requirement of virtual resource utilization and storage capacity necessitates making IoT applications smarter; therefore, integrate the IoT concept with cloud computing will play an important role. This is crucial because of very large amounts of data that IoT is expected to generate. The Cloud of Things (CoT) is used to connect heterogeneous physical things to the virtual domain of the cloud. Despite its numerous advantages, there are many research challenges with utilization of CoT that needs additional consideration. These include high complexity, efficiency, improving reliability, and security. This chapter introduces CoT, its features, the applications that use CoT. CoT, like all other networked functions, is vulnerable to security attacks. The security risks for CoT are listed and described. The security requirements for CoT are identified and solutions are proposed to address the various attacks on CoT and its components.
