By 2050, urban population internationally will have increased by 2.8 billion people. Moreover, at the current rate of carbon emissions, global temperatures will have risen by 2℃ from pre-industrial levels. Therefore, there is an urgent need to plan the cities of the future for sustainability. As a major agent for promoting a quality of life compatible with a resource efficient economy, the smart city phenomenon has recently captured the imagination of the academia and the industry alike. Since the Internet of things (IoT) is expected to be a primary driving force for future cities, advanced communication techniques will play a pivotal role in facilitating real-time data acquisition and utilization from distributed sensors. However, future cities will also have to operate within the constraints of the national economy and available power resources. Consequently, the challenges in the realization of smart cities are many and varied, such as low energy consumption requirement, constrained bandwidth and budgetary limitations. In order to overcome these hurdles, it is essential that new concepts and theories for optimizing the network in energy, spectral and monetary terms are presented to achieve a robust environment monitoring and sustainable transportation network, among other provisions. This workshop is aimed at furthering this effort by forging collaborations through the presentation of state-of-the-art research endeavors by scholars from across the globe. The participants will have the opportunity to share their findings with the academic community at large as well as to form collaborations to jointly investigate new aspects of smart cities.
