Recent advances in cutting-edge wireless communication and computing te- nologies have paved the way for the proliferation of ubiquitous infrastructure and infrastructureless wireless networks. These emerging networks are enabling a broad spectrum of applications ranging from critical infrastructure prot- tion and security, to environment monitoring, health care, and quality of life. The need to deal with the complexity and rami?cations of the ever-growing mobile users and services, however, is intensifying the interest in the devel- ment of sound fundamental principles, novel algorithmic approaches, rigorous and repeatable design methodologies, and systematic evaluation frameworks for next-generation wireless networks. The Third International Conference on Wireless Algorithms, Systems and Applications (WASA) was held in Dallas, TX, USA during October 26-28. The objective of WASA is to address the research and development e?orts of va- ous issues in the area of algorithms, systems and applications for current and next-generationinfrastructureandinfrastructurelesswirelessnetworks. Thec- ference is structured to provide a forum for researchers and practitioners, from the academic, industrial, and governmental sectors, with a unique opportunity to discussandexpresstheirviews onthe currenttrends, challenges, andstate-- the-artsolutionsaddressingvariousissuesrelatedtocurrentandnext-generation wireless networks. Following a rigorous review process, the Program Committee selected an outstanding set of 35 papers for publication in the proceedings and oral presentations at the conference. The program of WASA 2008 also included three keynote talks by Lionel Ni, Ty Znati, and Jie Wu along with 15 invited paper
