The ever-increasing need for higher data rates in multimedia services and applications leads to stringent requirements on the bit rate/km2 that next-generation cellular wireless networks are expected to deliver. This increasing trend has urged mobile operators to examine new ways for improving their coverage and boosting their network capacities. A promising approach to this challenge is the dense deployment of short range, low-power and low-cost base stations or access points in conjunction with the macrocellular network, as well as relays, distributed antennas and radio remote heads. However, the CAPital and OPerating EXpenditures (CAPEX and OPEX) of such heterogeneous networks increase with the increasing number of nodes. The solution to this problem is the deployment of Self-Organizing NETworks (SONETs). SONETs represent a novel paradigm based on the deployment of networks with self-organized functionalities. There are significant technical problems that need to be addressed for the successful deployment and operation of SONETs. In particular, time-, frequency- and spatial-domain interference management is a fundamental issue. To deal with increasing peak data demands, SONETs design should be self-organized based on interference/load/congestion levels, dynamically adapting their transmissions and using smart traffic offloading strategies onto licensed/unlicensed bands. The IEEE International Workshop on Self-Organizing NETworks (SONETs) offers an excellent opportunity for academic and industrial researchers to spread and share the latest results and understandings for rendering wireless networks more efficient in terms of capacity, coverage, Quality-of-Service performance and energy consumption.

Wireless operators continue to address the increase in wireless resources requested by mobile users. Recently various approaches to that problem have been investigated, one of which assumes the introduction of dedicated small cells, where the considered small geographical area is served by low-range access points (or small base stations) creating a heterogeneous deployment where multiple small cell types coexist, such as picocells, microcells, metrocells, femtocells or WiFi zones. These deployments allow significant capacity enhancements and better coverage conditions that can be particularly beneficial for enhancing the bit rates of the users that are located at the edges of the macrocells. Such advanced topologies composed by multiple cell sizes and involving the combination of different radio access technologies are usually known as heterogeneous networks, or simply as HetNets. Standardization bodies have considered HetNets to be a promising technology for the next generation cellular networks because of their many attractive features and benefits to both network operators and consumers. However, the practical deployment of HetNets still poses some critical issues and challenges, such as the requirement of efficient interference coordination mechanisms to ensure that the mutual interference between different cells is kept below acceptable limits. This workshop aims to address various aspects of interference management and design issues in future heterogeneous networks.

Device-to-device (D2D) communications underlaid on wireless cellular networks is viewed as a key technology for providing seamless, high-quality wireless access in next-generation wireless systems. The D2D concept is built around the idea of allowing the wireless devices to communicate with one another via direct D2D links over both the licensed and unlicensed spectrum. Unlike traditional short-range D2D technologies such as Bluetooth or Zigbee, D2D over cellular is expected to provide high capacity and guaranteed QoS over long ranges. D2D is also expected to lead to novel wireless applications such as proximity services and public safety communications. Indeed, D2D is seen as a key feature of 5G wireless systems. However, reaping the benefits of D2D requires handling several challenges, such as interference management, self-organization, network discovery and resource allocation, among others.  The goal of this workshop is to bring together academic and industrial researchers to identify and discuss technical challenges and recent results related to D2D and public safety communications. Topics of interest are diverse and include, but are not limited to, the following: resource allocation, neighbor discovery, energy efficiency and multi-hop communications in D2D, mobility, traffic and channel modeling in D2D and public safety communication, game theoretic D2D models, interference management and localization in D2D, experimental results on D2D performance in proximity services and public safety scenarios, and applications of D2D in public safety communications and adjunct domains.

The Internet of Things (IoT) is a novel design paradigm envisioned as a network of billions or trillions of machines communicating with one another and rapidly gaining global attention from academia, industry and government. IoT is recognized as one of the most important areas of the future Internet, enabling ubiquitous computing among global networked machines and physical objects. Equipped with auto identification devices such as RFID tags, in addition to sensors, actuators and machine-to-machine (M2M) devices, IoT has applications in a wide variety of areas: smart grid, e-health, intelligent transportation and logistics. The IEEE WCNC 2014 International Workshop on the Internet of Things Communications and Technologies follows the steps of the successful IEEE WiMob 2013 IoT workshop. It aims to provide a forum that brings together researchers from academia and practitioners from industry, as well as standardization bodies and government, to meet and exchange ideas on recent research and future directions for the IoT. The technical discussion focuses on the communications aspects and key enabling technologies for IoT, especially M2M communications and networking, RFID technology and Near Field Communications (NFC).

With the rapid proliferation of advanced wireless communication technologies and services, wireless communications are now facing many emerging challenges, including spectrum demand and network capacity limitations. The subscriber base has grown dramatically, and the world’s economy and society are increasingly dependent on wireless communications. The challenge of this workshop is to identify decisive requirements and user expectations, system concept paradigm shifts, key radio technology enablers, promising research directions and potential regulatory issues that will play an important role in shaping future Wireless Networks in the era beyond 2020.

The workshop is organized by the Wireless World Research Forum (WWRF). WWRF’s goal is to encourage global research that will achieve unbounded communications to address key societal challenges for the future. The term “Wireless World” is used in a broad sense to address the support of innovation and business, social inclusion and infrastructural challenges. This will be achieved by creating a range of new technological capabilities from wide-area networks to short-range communications, machine-to-machine communications, sensor networks, wireless broadband access technologies and optical networking, along with increasing intelligence and virtualization in networks. This will support a dependable future Internet of people, knowledge and things and the development of a service universe.

This workshop explores novel concepts for flexibly centralized radio access networks using cloud processing based on open IT platforms, allowing for a high-quality experience for mobile access to cloud processing resources and services, and providing for a future network evolution focused on energy efficiency and cost effectiveness. In fact, all future innovative network solutions will be conceived and deployed with a long-term perspective of sustainability, both in terms of energy consumption of the mobile network (and related interoperability with terminals) and cost efficiency of the different deployment and management options. This requires new concepts for the design, operation, and optimization of radio access networks, backhaul networks, operation and management algorithms and architectural elements, tightly integrating mobile networks and cloud processing. This workshop addresses technologies across PHY, MAC and network layer. It covers technologies that translate the cloud-computing paradigm to the radio access and backhaul network, and analyzes all the network evolutions from the energy efficiency perspective. It studies the requirements, constraints and implications for mobile communication networks, as well as the potential relationship with the offered service, from both an academic and industrial point of view.
