In recent years, the capabilities of contemporary mobile devices have been improving a lot. These capabilities, such as significant computational resources, multiple communication radios, various sensor modules, and high level programming languages, enable mobile devices to form mobile cyber-physical system (CPS) in our daily lives. Mobile CPS integrates distributed sensing with computing and ubiquitous connectivity of Internet. Also, mobile CPS coordinates computational, virtual, and physical

Thus, mobile CPS could provide a convenient and economical platform that facilitates sophisticated and ubiquitous intelligent applications between humans and the surrounding physical world. Mobile CPS could find applicability in multiple areas and disciplines, including (but not limited to) (1) mobile intelligent robots and robotics systems, making use of multiple smart sensors, mobile devices, intelligent service, cloud robots, and so on, to improve efficiency and scalability in processing of complex tasks that are impossible under local resource constraints in different application areas; (2) intelligent transportation systems, for example, leveraging sensing, computing, and communication capabilities with control vehicles in the physical world to deal with the challenges of safe (e.g., decreasing time latency of reaction in traffic accidents), efficient, and green transportations; and (3) smart living technologies, for example, smart city, environmental monitoring, healthcare systems, and smart grid, which improve intelligence, convenience, operational safety, and green energy of human society. The purpose of this special issue aims to involve multidiscipline research contributions of unpublished research on the recent methodologies, innovations, and experimental validations regarding mobile CPS, so as to facilitate the real-world deployment of such systems in the future. In this special issue on mobile CPS, we have invited a few papers that achieve such goal. The paper "Sliding Window Based Feature Extraction and Traffic Clustering for Green Mobile Cyber-Physical Systems" focuses on a green mobile cyber-physical system to ensure network coverage and to reduce the total energy consumption, which proposes a feature extraction method using sliding window to extract the distribution feature of mobile user equipment (UE). Furthermore, traffic clustering analysis and corresponding optimized control strategy are presented for the rapid control of base stations. Experimental results demonstrate the superior performance of the proposed method in terms of UE coverage compared with the grid method. The paper "An Anonymous Access Authentication Scheme Based on Proxy Ring Signature for CPS-WMNs" proposes a novel anonymous access authentication scheme based on proxy ring signature to address the anonymous access authentication issue for CPS-Wireless Mesh Network (CPS-WMN). In the scheme, a hierarchical authentication architecture is presented firstly. Then, intergroup and intragroup anonymous mutual authentication are carried out through proxy ring signature mechanism and certificateless signature mechanism, respectively. A formal security proof with SVO logic and simulation results demonstrate the security and the performance of the proposed scheme.
