This book constitutes the refereed proceedings of the 7th International Conference on Ad-Hoc, Mobile, and Wireless Networks, ADHOC-NOW 2008, held in Sophia-Antipolis, France, September 2008. The 40 revised full papers and the 15 poster presentations were carefully reviewed and selected from 110 submissions. The papers deal with advances in Ad-Hoc networks, i.e. wireless, self-organizing systems formed by co-operating nodes within communication range of each other that form temporary networks. Their topology is dynamic, decentralized, ever changing and the nodes may move around arbitrarily.
