It is widely acknowledged that Smart Cities will drive sustainable economic growth in the next years and ICT represents one of the enabling factors for their actual implementation. The problem of efficiently supporting applications and services for Smart Cities in complex, distributed and diverse environments has been and is continuing to be the subject of intense research investigation. Wireless and Mobile Technologies play an essential role in the new and challenging scenario of Smart Cities. The main purpose of the WiMobCity Workshop is to bring together researchers/academics/developers in the field of Smart Cities (and in particular on the related topics of Wireless and Mobile communication technologies and networking) in order to share new findings, exchange ideas, discuss research challenges and report latest research efforts that cover a variety of topics including, but not limited to: Communication technologies, architectures and wireless/mobile protocols (WiFi / LTE / 4G) Radio Frequency Identification (RFID), Near Field Communication (NFC) and Wireless Sensor Networks (WSNs) communication technologies Machine-to-Machine (M2M) communications Quality of Service (QoS) / Quality of Experience (QoE) mechanisms Green and energy efficient technologies Security and privacy communication issues for Smart Cities Data management and access methods (cloud, crowdsourcing, etc.) Pervasive Internet of Things (IoT) and mobile computing Innovative applications and services for sustainable cities Business models, billing approaches and new services for Smart Cities Smart Cities deployments, platforms, test-beds and field trials Standardization activities for Smart Cities
