Routing is an important function in MANETs. Performance of various Proactive, Reactive and Hybride Routing Protocol have been studied, analyzed and evaluated through the simulations in Network Simulator-2. Early work in routing mainly focussed on providing efficient mechanisms for finding paths in dynamic networks. Security issues were not taken into consideration. Interestingly, designing adequate security schemes for these innovative networks is very challenging. The objective of writing this book are (i) To make the readers aware of the fundamentals of Mobile Ad hoc Networks and its...
