Wireless networks are nowadays considered a founding part of the global communications and computing infrastructure that we broadly refer to as “the Internet”. Their inherent ability to support users on the move and to seamlessly interface with a variety of communications-enabled devices has opened up a number of novel research areas, including, e.g., Internetof-Things and pervasive computing environments. At the same time, their use as de facto standard for accessing Web-based services is becoming more and more relevant with the introduction of LTE/LTE-Advanced technologies for cellular networks. In this perspective, the ability to model wireless networks at the system level and to optimise their internal functioning in various operational conditions is becoming a key factor for ensuring that the innovation pace in wireless networks technologies can be maintained. This Special Issue of MONET contains four articles, representing extended versions of papers presented at WiOpt 2009. The 2009 edition of WiOpt represented the 7th edition of the series of Symposia on Modelling and Optimization in Mobile, Ad Hoc, Wireless Networks. The symposium took place in Seoul in June 2009
