The book "Mobile Ad-hoc Networks" provides a comprehensive introduction to the world of mobile ad-hoc networks (MANET). These networks are characterized by their dynamic, self-organizing, and self-configuring nature, allowing a group of mobile nodes to communicate directly with one another without relying on a fixed communication infrastructure or central management. The author, Mohamad T. Sultan, explains how routing works and the associated protocols responsible for transmitting information between the nodes. Additionally, the applications of MANET and the security-related challenges associated with these networks are discussed. This technical book is aimed at readers who wish to develop a deeper understanding of the technology and challenges of mobile ad-hoc networks.
