This paper provides an overview of the Internet of Things (IoT) with emphasis on enabling technologies, protocols, and application issues. The IoT is enabled by the latest developments in RFID, smart sensors, communication technologies, and Internet protocols. The basic premise is to have smart sensors collaborate directly without human involvement to deliver a new class of applications. The current revolution in Internet, mobile, and machine-to-machine (M2M) technologies can be seen as the first phase of the IoT. In the coming years, the IoT is expected to bridge diverse technologies to enable new applications by connecting physical objects together in support of intelligent decision making. This paper starts by providing a horizontal overview of the IoT. Then, we give an overview of some technical details that pertain to the IoT enabling technologies, protocols, and applications. Compared to other survey papers in the field, our objective is to provide a more thorough summary of the most relevant protocols and application issues to enable researchers and application developers to get up to speed quickly on how the different protocols fit together to deliver desired functionalities without having to go through RFCs and the standards specifications. We also provide an overview of some of the key IoT challenges presented in the recent literature and provide a summary of related research work. Moreover, we explore the relation between the IoT and other emerging technologies including big data analytics and cloud and fog computing. We also present the need for better horizontal integration among IoT services. Finally, we present detailed service use-cases to illustrate how the different protocols presented in the paper fit together to deliver desired IoT services.

Internet of Things: A Survey on Enabling Technologies, Protocols, and Applications

Mobile edge computing (MEC) is an emergent architecture where cloud computing services are extended to the edge of networks leveraging mobile base stations. As a promising edge technology, it can be applied to mobile, wireless, and wireline scenarios, using software and hardware platforms, located at the network edge in the vicinity of end-users. MEC provides seamless integration of multiple application service providers and vendors toward mobile subscribers, enterprises, and other vertical segments. It is an important component in the 5G architecture which supports variety of innovative applications and services where ultralow latency is required. This paper is aimed to present a comprehensive survey of relevant research and technological developments in the area of MEC. It provides the definition of MEC, its advantages, architectures, and application areas; where we in particular highlight related research and future directions. Finally, security and privacy issues and related existing solutions are also discussed.

Mobile Edge Computing: A Survey

Intelligent Manufacturing in the Context of Industry 4.0: A Review

There has been significant interest and progress in the field of vehicular ad hoc networks over the last several years. VANETs comprise vehicle-to-vehicle and vehicle-to-infrastructure communications based on wireless local area network technologies. The distinctive set of candidate applications (e.g., collision warning and local traffic information for drivers), resources (licensed spectrum, rechargeable power source), and the environment (e.g., vehicular traffic flow patterns, privacy concerns) make the VANET a unique area of wireless communication. This article gives an overview of the field, providing motivations, challenges, and a snapshot of proposed solutions.

A tutorial survey on vehicular ad hoc networks

Mobile ad hoc networks (MANETs) represent complex distributed systems that comprise wireless mobile nodes that can freely and dynamically self-organize into arbitrary and temporary, ‘‘ad-hoc’’ network topologies, allowing people and devices to seamlessly internetwork in areas with no pre-existing communication infrastructure, e.g., disaster recovery environments. Ad hoc networking concept is not a new one, having been around in various forms for over 20 years. Traditionally, tactical networks have been the only communication networking application that followed the ad hoc paradigm. Recently, the introduction of new technologies such as the Bluetooth, IEEE 802.11 and Hyperlan are helping enable eventual commercial MANET deployments outside the military domain. These recent evolutions have been generating a renewed and growing interest in the research and development of MANET. This paper attempts to provide a comprehensive overview of this dynamic field. It first explains the important role that mobile ad hoc networks play in the evolution of future wireless technologies. Then, it reviews the latest research activities in these areas, including a summary of MANETs characteristics, capabilities, applications, and design constraints. The paper concludes by presenting a set of challenges and problems requiring further research in the future. � 2003 Elsevier B.V. All rights reserved.

Mobile ad hoc networking: imperatives and challenges

Maximum-likelihood (ML) receivers are optimum receivers for MIMO systems, but their complexity grows exponentially with the modulation order of the codeword and the number of spatial layers. The Reduced Complexity ML (R-ML) receivers based on low complexity adaptation of the max-log MAP detector and reduction of searching space are a good compromise to satisfy complexity-performance trade-off. In this paper we investigate physical layer abstraction for singleuser MIMO system with a R-ML receiver performing Parallel Interference Aware (PIA) detection. We develop a light-weight extended Mutual Information Effective SINR Mapping (MIESM) methodology based on look-up tables (LUT), which take the special non-linear nature of the PIA receiver into account. The results show that the proposed LUT-based MIESM abstraction method is as accurate as the direct MIESM abstraction, but at the same time has significantly less computational complexity. It can thus be easily used in performance prediction devices as well as system level simulators.

Phy layer abstraction for SU-MIMO LTE system employing parallel interference-aware detection

The current evolution of the global Internet data traffic shows an increasing demand of video transmissions, which potentially leads to the saturation of mobile networks. To cope with this issue, this paper describes techniques to handle the video traffic load in the last hop, of the communication network, i.e., the wireless access. The general idea is to benefit from a cross-layer architecture for efficient video transport, where multiple wireless access technologies, represented by Wi-Fi and next generation cellular technologies (4G and beyond), interact with the upper layers through an abstract interface. This architecture enables the introduction of enhancements in the LTE-A wireless access: evolved Multimedia Broadcast and Multicast Services (eMBMS) extended with dynamic groupcast communications, video relay at the Packet Data Convergence Protocol (PDCP) level and a smart video frame dropping mechanism to provide mobile users with a satisfactory level of Quality of Experience (QoE). These video-aware mechanisms leverage the abstract interface and allow mobile operators to fine-tune their networks while coping with the upcoming mobile video traffic increase.

Enhancing Video Delivery in the LTE Wireless Access Using Cross-Layer Mechanisms

This paper gives an overview of the French collaborative project SAMU, Advanced Services by Mastering UMTS, dedicated to developing enhanced services for users in a car. For that purpose, complementary research domains have been investigated such as radio resource management, IP over UMTS and the use of software agents. While field trials were planned in the project to validate the outputs of the abovementioned research areas over a UMTS experimental network, the general delay encountered by UMTS manufacturers led the project to investigate alternative experimentation. Hence, a UMTS-TDD software radio platform has been built to show IP based telematics applications over UMTS.

This paper evaluates our work of Scalable Proxy Mobile IPv6 (SPMIPv6) in a Wireless Mesh Network (WMN), which is a promising solution for ubiquitous Internet access and a wide range of applications. The aspects of scalability and signaling cost are evaluated respectively: the scalability is evaluated by numerical analysis while the signaling cost with respect to delay is evaluated by a virtualization-based method. It is shown that the SPMIPv6 extension can scale the network better than the base Proxy Mobile IPv6 (PMIPv6) protocol. The quantitative results are provided to complete our previous qualitative results and to validate the application of SPMIPv6 for WMN.

Evaluation of Scalable Proxy Mobile IPv6 in Wireless Mesh Networks

In recent times, rapid introduction of the Internet of Things (IoT) services in smart environment domain has happened. This has introduced heterogeneous device and data types that lack proper mechanism for joint execution of tasks from an application perspective. In this paper, we propose an integrated indoor environmental monitoring system implemented with a novel IoT framework. It is enabled via fuzzy-based rule schema to resolve the heterogeneity of environmental data in smart home environment. The novel aspect of the framework is that it is developed with a modular repository together with decision-making modules. Our experiments prove this approach to be a viable IoT solution for smart home indoor environment.
