Of late, the use of Mobile Ad-hoc Network (MANET) is gaining momentum in military and commercial applications. Due to some unique characteristics of MANET, it is important that appropriate network and transport layer protocols be deployed to effectively maintain such network. Despite that many MANET routing protocols and TCP variants have been developed in recent years, current literature reveals only a limited number of studies on their performance. More specifically, very few researches hitherto had been attempted to realistically evaluating their performance. This book, therefore, has contemplated four routing protocols along with three existing TCP variants in order to assess their performance in a few realistic MANET scenarios, which eventually help better understand their comparative merits and suitability for deployment under different network scenarios. In this context, it presents a description on aspects related to the task of MANET modeling and experimental designs. The book is targeted not only to the students and researchers working with MANET, but also to the practitioner-engineers who design ad-hoc network models in real life applications.
