WiOpt 2013, 11th International Symposium on Modeling and Optimization in Mobile, Ad Hoc, and Wireless Networks, intends to bring together researchers and practitioners working on modeling and optimization of wireless network design and operations. It welcomes original, high-quality works on different perspectives, including performance analysis and simulation, algorithms and protocol design, optimization theory and application, information theoretic analysis including capacity scaling, for all forms of wireless networks: cellular, metropolitan, ad hoc, delay-tolerant, mesh, sensor networks as well as any combination of these. Contributions to the symposium should improve the state-of-the-art in design, analysis, dimensioning and operations of wireless network by providing insights into theoretical aspects as well as providing practical methods and tools. All forms of wireless networks are of interest: from cellular wide-area and local-area networks to dense and sparse ad-hoc networks; domain specific vehicular, public-transport and personal-area networks as well as application-specific sensor networks. Technical papers describing original, previously unpublished research, not currently under review by another conference are solicited.
