Special Section on Optimization algorithms for Industry 4.0
Industry 4.0 is a term coined to signify the dramatic changes and revolution occurring in manufacturing process by leveraging the services of cyber-physical systems. The driving forces behind industry 4.0 revolution are big data analytics, simulation, robotics, Internet of Things (IoT), system integration both horizontally and vertically, Cloud and other forms of distributed computing paradigms, cyber security, augmented reality and additive manufacturing. Gone are the days where there was a stiff competition between companies in terms of the product manufactured. The trend has shifted in such a way that competing companies are measured or ranked based on how well they have embraced the above technologies into their manufacturing process and adapted to the evolving changes across these areas. In simple terms Industry 4.0 can be termed as computerization of Industry 3.0. Industry 4.0 provides a perfect platform in identifying business opportunities and identifying the key areas and features that may cater to these new and exciting opportunities.
Several aspects need to be considered while developing an optimized approach. It must also be noted that adapting to these technologies alone is not sufficient and by adapting to these technologies there should be a significant impact to the manufacturing process on a positive front. Most of these technologies are new and hence most of the approaches and algorithms used across these technologies are also naïve. In other words the mere adapting of these technologies into the manufacturing process alone will not yield better results, the focus should also be directed towards how these raw concepts, approaches and algorithms can be optimized to produce better results. Another aspect that needs to be considered during optimization is to have an eye on the futuristic evolutions and changes that might impact the current process. Also, the optimized algorithms should be aimed at providing robust, secure and stable and consistent results over a manufacturing period. Another aspect that needs to be contemplated is the scalability and portability of the algorithm in terms of features and volume of data that it can handle. The real challenge for several researchers is to enhance and optimize these existing approaches by considering all these aspects.
This special section provides a platform to share original ideas related to optimizing algorithms pertaining to several technologies that are driving forces for Industry 4.0. Also new ideas and approaches that enhance the performance of existing algorithms and any complexity reduction techniques which lead to performance enhancements can be shared.

Special Issue on "Novel techniques for managing and processing information in the Web, Mobile, and IoT technology era"
The World Wide Web, once a single interconnection of static, physically distributed content passively accessed by human users through personal computers, is constantly evolving. During the explosion of Web-based social networks the Web evolved into an environment allowing millions of users worldwide to interact and collaborate in the creation of user-generated content within many virtual communities. In this line, Web 2.0 is the umbrella term used to encompass several developments which followed, namely social networking sites and social media sites (e.g., Facebook), blogs, wikis, folksonomies (e.g. Flickr), video sharing sites (e.g., YouTube), Web applications ("apps"), collaborative platforms, and mashup applications. Many technologies such as HTML 5, CSS3, AJAX and client-side scripting helped to bring these ideas into practice.
Moreover, the current Web can be seen as an evolutionary step from the Web 2.0 in that access to content is nowadays ubiquitous, and content itself is far more heavy and heterogeneous than ever. First, ubiquitous access has been mainly pushed by the inception of mobile computing and mobile devices; in fact reports show that by 2020 the number of mobile device users will be about 70% of the global population. Second, served and published Web content is not only those following traditional interchange formats (text, images, video) but also e.g. executable code/Web APIs (e.g. Mashape.com, ProgrammableWeb.com), from which new applications can be built and in turn published back to the Web. The recent notion of "Web of objects", which find its root in Web-accesible IoT applications, promotes the interconnection of hardware elements capable of producing huge amounts of sensor data.
Moreover, the role of Web application end users and Web developer/designers is nowadays somewhat blurry, due to modern Web technologies that greatly simplify the creation/deployment of rich Web sites and mobile applications that might consume Web-accesible services and data. In addition, the advent of Semantic Web technologies pave the way to the creation of intelligent applications, and thus the tandem human user-browser is no longer the only way to take advantage of Web content.
In this context, the huge and heterogeneous nature of today’s Web content, in addition to the different sources of clients exploiting it (regular users, developers, automated applications) calls for advanced information processing and management techniques to answer the following research questions: how to extract and learn valuable information from existing Web content? how can different Web sources be fused/aggregated to produce new, consistent information? How to ensure scalability in light of huge sources of Web data? In short, novel approaches and techniques are needed to address the increasing complexity of the Web that is coming and the applications therein. We solicit high-quality papers proposing solutions and approaches to cope with these problems.

Special Issue on 5G Radio Access Network Design and Optimization
5G mobile systems are expected to support highly dynamic traffic and stringent delay requirements. Pervasive deployment of a large number of low-power small base stations
(BSs) with possibly overlapped radiation ranges appears to be the most viable solution to meet the requirements. C-RAN is promised to serve in such a scenario by centralizing the baseband units (BBUs) of the BSs into a common BBU pool, while leaving the remote radio units (RRUs) geographically distributed over a wide area for providing radio transmission/reception functions. The centralization of the baseband processing functions shall provide remarkable benefits in terms of resource sharing and most importantly, a seamless inter-BBU collaboration for interference mitigation. The antennas, with all the radio-frequency functionalities and minimal local processing, are hosted at the RRUs, while modulation/demodulation and precoding/decoding are performed at the BBUs.
A tremendous amount of research works regarding the 5G C-RAN design, modelling, and optimization has been reported in the past a few years. However, there are still a number of open issues to be addressed, including the design of front-hauls, the C-RAN backbone interconnections, and the indoor distribution system, etc., which are crucial in supporting the rich and heterogeneous mobile services in the future 5G networks.
The SI is positioned to serving as a platform of gathering a number of researchers in the area of 5G C-RAN design and operation to present their the most state-of-the-art contributions to the related topics, which include but not limited to:
1. CPRI function split schemes and performance evaluation
2. C-RAN designs for emerging applications and service requirements (e.g., IoT, V2x, massive MIMO, and URLLC)
3. C-RAN designs for indoor distributed systems
4. C-RAN for supporting 5G indoor/outdoor positioning systems
