From the turn of the new millennium, the decentralisation movement has gained more and more attention. Popular examples, which are given not only from pure technical viewpoint, but also from the user viewpoint, include eBay, Expedia, YouTube, Skype, iPhone, Bluetooth, BitTorrent, Gnutella, various commercial sensor networks motes, SETI@home, etc. The core of the decentralisation movement is the idea of giving more autonomy, more control, and more respect to ordinary users of a computing system, or a network, or a product. With fast growing user body of more fancy cell phones and other mobile devices, the technical trend has been blend into a world-wide cultural fashion. This book discusses all these issues with focus on bootstrapping and routing of the synergised P2P systems over MANETs.
