An implementation of Ad-hoc On-demand Distance Vector (AODV) protocol, already made available by National Institute of Standards and Technology (NIST) to facilitate researchers, is used as a benchmark to compare our findings. This book may also be useful for young researchers who want to work with the OPNET modeler for conducting simulations. This book is based on a research idea which exploits the relative mobility of nodes in mobile ad-hoc networks (MANET) for the enhancement of overall throughput of the network. The hypothesis is proved using simulations in the OPNET modeler, a tool built for the purpose. Packet formats of AODV protocol are altered to facilitate the required algorithms. Source code of work done during our research is available for furthering our ideas and may be requested through an email to Idrees@pucit.edu.pk.
