In the next generation of wireless communication systems, there will be a need for the rapid
deployment of independent mobile users. Significant examples include establishing survivable, efficient,
dynamic communication for emergency operations, disaster relief efforts, and military networks. Such
network scenarios cannot rely on centralized and organized connectivity, and can be conceived as
applications of mobile ad hoc networks. A MANET is an autonomous collection of mobile users that
communicate over relatively bandwidth constrained wireless links. Since the nodes are decentralized, where
all network activity including discovering the
The telecommunications industry has seen a rapid boost within the last decade. New realities
and visions of functionalities in various telecommunications networks have brought forward the
concept of next-generation networks (NGNs). The competitions among operators for support-

This book addresses the issues on the development of next generation CDMA technologies and
contains a lot of information on the subject from both the open literature and my own research
activities in the last fifteen years.
Abstract: Stuxnet, a sophisticated virus that damaged Iran's nuclear capability, should be an eye openerfor the world. We can choose to learn something very narrow (how to combat the Stuxnet virus) or wecan choose to focus on the larger goal of thwarting the next type of creative cyber attack. Unfortunately,critical industrial infrastructure is not currently designed with security as a key goal, leaving open multipleavenues for an educated and funded attacker to create massive problems. This tutorial outlines somebasic concepts that engineers and product definers should consider to make sure their new projects stayahead of future threats.
