In recent years mobile ad-hoc networks (MANET) become very popular and useful for communication. MANET is a collection of wireless mobile hosts forming a temporary network without the aid of any centralized administration or standard support services. This network has the advantage of being able to be setup and deployed anywhere and anytime because of it's simple infrastructure setup. This book, review the MANET and recent routing protocols for efficient communication. Then it investigates the current and existing security issues associated with the ad-hoc wireless routing protocols and exposes any slack amongst them in order to lighten possible problem domains in this field of wireless mobile networks.
