Abstract
The increasing demand for wireless services and the scarcity of the available electromagnetic spectrum necessitate aggressive spatial reuse of frequency bands, which makes interference the main performance-limiting factor in current and future wireless systems. Interference critically depends on the location of the concurrent transmitters, i.e., the network geometry. As a result, space is rapidly becoming the critical resource, and a key issue in the design of efficient network architectures is space management, in terms of infrastructure placement, channel access, and choice of transmission technology.

Until recently, these problems were mostly addressed using large-scale simulations, which are expensive and only provide limited insight. As a powerful alternative, we describe an analytical approach to wireless network modeling, analysis, and design based on stochastic geometry. The key idea is to model the locations of the terminals as a stochastic process and calculate distributions of the relevant network metrics over ensembles of network configurations.

We illustrate this approach using examples in cellular, heterogeneous, device-to-device, cognitive, and vehicular networks and demonstrate how it helps overcome challenges posed by the QoS and QoE demands for current and novel services in next-generation networks.
