Design and Evaluation of Ad Hoc Routing Protocol: (ISTE Consignment)

Design and Evaluation of Ad Hoc Routing Protocol examines ad hoc communications between vehicles in a road environment. In this context, the book questions the sustainability of communications-dependent driver assistance services in areas where no communications infrastructure is operational. Starting with an ad hoc routing protocol proposed by the authors, this book presents a methodology from its design to its evaluation. It presents the functional requirements-based design approach and offers analyses to help us understand how the protocol functions, its properties and its performance in relation to target applications. This book is primarily aimed at beginners in the fields of protocol engineering, ad hoc networks or intelligent transport systems, but also provides specialists with an original perspective on the scientific literature in these fields. In particular, it offers concrete tools to help them develop their own methods for designing and evaluating communications protocols.
