The article presents the discussion on meaning or semantics of the data. Topics include advancements in artificial intelligence (AI) providing a powerful tool for solving fundamental problems in semantic communications; and semantic communications in emerging wireless networks such as virtual reality and autonomous driving.

The article reports that In contrast to the Shannon paradigm whose underlying principle is to guarantee the correct reception of each single transmitted packet regardless of its meaning, semantic communication is concerned with the problem of how transmitted symbols convey a desired meaning to the destination, as well as how effectively the received meaning affects the action in a desired way.

Verification of theoretical analysis is a vital step in the development of an application or a protocol for wireless networks. Most proposals are evaluated through mathematical analysis followed by either simulation or experimental validation campaigns. In this article, we analyze a large set of statistics in articles published (674 papers in total) in the top representative ad hoc and wireless sensor networks related conferences (i.e., ACM/ IEEE IPSN, ACM MobiCom, ACM MobiHoc, and ACM SenSys) during the period 2008?2013. We focus on the evaluation methodologies provided by researchers. More specifically, our goal is to explore the role of simulators and testbeds in the theoretical analysis of a model throughout the protocol development procedure. We show that there is a tendency for more and more researchers to rely on custom or open testbeds in order to evaluate the performance of their proposals. Simulators indeed fail to reproduce actual environmental conditions of deployed systems. Experimentation with real hardware allows our research community to mind the gaps between simulation and real deployment. Still, as the experimental apFproach through custom testbeds results in a low reproducibility level (i.e., 16.5 percent), we investigate to what extent such performance evaluation methods will be able to bridge those gaps. We finally discuss experimental testbeds and their potential to replace simulators as the cornerstone of performance evaluation procedures. [ABSTRACT FROM PUBLISHER]

In order to deal with the challenges and opportunities presented by the mobile Internet, this paper proposes a new Internet-oriented mobile network architecture, dubbed i-Net, for fifth generation (5G) mobile communication systems. Based on direct communications established between the base stations (BSs), i-Net can implement local data routing for mobile data traffic, which adapts to increased service localization for the mobile Internet. We first present the network architecture and main technical features, i.e., inter-connection, integration, and intelligence. Then the key techniques are discussed to show their potential in improving the network efficiency of i-Net. Field trials for inter-BS direct communications to implement cooperative multipoint oPeration (CoMP) in i-Net are carried out to demonstrate the feasibility of i-Net. It is expected that i-Net can provide a good quality of experience for end users through the efficient integration of the multi-BS, multi-band, and multi-radio-access-technology (RAT) radio resources in 5G.

5G, the mobile communication technology for beyond 2020, will provide access to information and the sharing of data anywhere and anytime for anyone and anything. This paper describes the current status of the processes moving toward 5G, or "IMT for 2020 and beyond," in ITU-R. We also provide a view of 5G opportunities, challenges, requirements and technical solutions. [ABSTRACT FROM PUBLISHER]

The large growth in mobile broadband traffic, wide support of Wireless Local Area Network (WLAN) technology in mobile devices, and the desire of operators to provide services anywhere at any time, have led to a need to integrate WLANs with the 3rd Generation Partnership Project (3GPP) Evolved Packet Core (EPC). This paper starts with a description of an architecture that 3GPP has defined to achieve this. It describes how a mobile device can set up an IP connection over WLAN routed via EPC without imposing new requirements on the mobile device. It also describes how more advanced features that do impose new requirements on the mobile device can be supported in an incremental fashion. [ABSTRACT FROM PUBLISHER]

In this paper, we examine upcoming 5G networks where the support of D2D communication is expected to be a key asset for operators and users alike. First, we argue the need to functionally integrate D2D and infrastructure-to-device (I2D) modes. Next, we address practical issues such as integrated resource scheduling of D2D communication within heterogeneous networks, proposing an extension of the proportional fairness algorithm that we call multi-modal proportional fairness (MMPF). We evaluate the impact of D2D in a two-tier scenario combining macroand micro-coverage, finding that although I2D retains a clear edge for general-purpose downloading, D2D is an appealing solution for localized transfers as well as for viral content.

Beyond-3G (B3G) systems have been envisaged as an evolution and convdergence of mobile/wireless communication systems and IP technologies to offer a multitude of services over a variety of access technologies. To fulfill the vision, it is necessary to understand the requirements with respect to the support of heterogeneity in network accesses, communication services, mobility, user devices, and so on. Besides, it is equally important to promote the necessary research in networking technology by providing a guiding framework of research areas and technical issues with priority. The new architectures and technologies will have to address the fundamental assumptions and requirements that govern the design. All these issues are being tackled by the Cooperative Network working group (CoNet) of WWRF; the group is working on a series of white papers outlining B3G visions and roadmap, architectural principles, research challenges, and candidate approaches. This article outlines the CoNet concept, architectural principles, and guidelines for research into cooperative networks assuming that the B3G systems will be built over generic IP networking technologies. The article also presents the key research challenges, research framework, and major network components and technologies. The key points are that the system should be layered on demand, encourage reuse of independent modularized functional blocks, support multiple services and service creation, ensure consistent end-to-end connectivity across different access technologies, and cooperate in terms of net- work control, operations, and maintenance. The architecture shall include the endpoints of communications as part of the communications system, and should provide a secure and trusted environment in which network functions are performed; the network should self-organize dynamically. Additionally, the article presents the IST WSI architecture proposed to CoNet as a reference model along with some approaches to the outlined research challenges. Finally, this study selects three important network components and technologies (i.e., mobility management, multiple access, and moving networks) in order to provide with answers and possible solutions the research challenges presented in earlier sections.

This is Part 2 of a Feature Topic (FT) series covering the convergence of communications, caching, and computing for next generation wireless mobile networks. The design and engineering philosophy of modern wireless networks is witnessing a fundamental shift from being "connection-centric" to being "content-centric". This FT aims to provide a comprehensive overview of recent progress in the theoretical foundation, architectural advances, modeling/analytics, protocol engineering, and prototyping of content-centric mobile networks. The response to our Call for Papers was overwhelming, with a total of 54 articles submitted by leading researchers and practitioners from around the world. Following a rigorous review process, Part 1 of this FT series, containing 12 articles, appeared in the August issue of IEEE Communications Magazine. The following additional six papers are selected to be included in Part 2 of the series. [ABSTRACT FROM PUBLISHER]
