ot only technologies, but also methodologies are evolving and changing the shape of network planning. This second part of this Feature Topic focuses on the technological side concerning wireless networks and the emerging methodologies to handle traffic uncertainty. The article “Vehicular Cloud Networking: Architecture and Design Principles” by Lee et al. sets out an architecture for networking and computation in a vehicular environment. The manifold applications that are enabled find broad interest, especially in the automotive and logistics industry. We deem the design principles proposed by the authors to be a helpful basis for research and development in the area. Boiardi et al. address, in “Planning for Energy Aware Wireless Networks,” the modeling and optimization of wireless networks aiming at energy efficiency. This aim is not only of high importance for greening these networks, but can also have a direct cost impact for operators. The authors show an approach by which energy-aware network planning can help achieve this aim. The article “Flow Level Models for Capacity Planning and Management in Interference-Coupled Wireless Data Networks” by Fehske et al. addresses capacity modeling of cellular networks. The growing adoption of mobile devices as well as higher per-device bit rates demands careful planning and management of capacity to ensure service quality levels. The authors propose facilitating flow-level models exploiting the dynamicity of traffic. In “Traffic Uncertainty Models in Network Planning,” Yang and Kuipers give an overview of and a toolset for modeling traffic uncertainty, which is an important issue in network planning given that traffic demands practically always differ from previous forecasts. Besides the offline and online models, we hold the future work directions to be indicative of upcoming research in the area. Bauschert et al., in “Network Planning under Demand Uncertainty with Robust Optimization,” also deal with uncertainty, focusing on the optimization and procedural aspects involved. The proposed use of robust optimization is emerging as a formidable means to address various complex network planning problems, and the article provides a great starting point for this approach.
