This book focuses on performance analysis of two routing protocols belonging to the basic categories (reactive, proactive) in mobile ad hoc networks. The book analyses the network performance over real-time variable bit rate traffic based on OLSR and AODV protocols belonging to basic categories reactive and proactive. Moreover, the book is about the impact of various mobility models on routing protocols described previously. Thereafter, it contributes in making choices of models and parameters to support real-time communications. Finally, we suggest a novel approach through Fuzzy logic to analyse and caculate the optimal delay and optimal throughput.
