This book constitutes the refereed proceedings of the First Euro-FGI International Conference on Network Control and Optimization, NET-COOP 2007, held in Avignon, France in June 2007.

The 22 revised full papers presented together with 9 invited lectures were carefully reviewed and selected from a total of 46 submissions. The papers address all current issues in network control and optimization, ranging from performance evaluation and optimization of general stochastic networks to more specific targets such as lower-layer functionalities in mobile networks, routing for computational grids, game theoretic approaches to access control, cooperation, competition and adversary capacities in diverse environments.
