In recent years, a lot of work has been done in an effort to incorporate Swarm Intelligence (SI) techniques in building an adaptive routing protocol for Mobile Ad Hoc Networks (MANETs). Since centralized approach for routing in MANETs generally lacks in scalability and fault-tolerance, SI techniques provide a natural solution through a distributed approach for the adaptive routing for MANETs. In SI techniques, the captivating features of insects or mammals are correlated with the real world problems to find solutions. Recently, several applications of bio-inspired and nature-inspired algorithms in telecommunications and computer networks have achieved remarkable success. The main aims/objectives of this book, "Mobile Ad Hoc Networks: Bio-Inspired Quality of Service Aware Routing Protocols", are twofold; firstly it clearly distinguishes between principles of traditional routing protocols and SI based routing protocols, while explaining in detail the analogy between MANETs and SI principles. Secondly, it presents the readers with important Quality of Service (QoS) parameters and explains how SI based routing protocols achieves QoS demands of the applications. This book also gives quantitative and qualitative analysis of some of the SI based routing protocols for MANETs.

We put them next to our sleeping babies and give them to our toddlers and children to play with. We use them for work, for entertainment, and for conducting our relationships. But how much do you know about mobile phones and other wireless devices and the radiation they emit? Did you know, for example, that your use of wireless devices can affect your children, your unborn children, and even your chances of conceiving? That wireless radiation has been shown to affect performance, mental health, relationships, and sleep? Or that many world authorities recommend reducing exposure to this radiation? "Smart" families are exposed to wireless radiation from "smart" devices. "Wise" families make informed decisions about using wireless technologies safely. This book, by consumer advocate and educator Lyn McLean, shows you in simple, practical terms what you need know to live wisely in our ever more connected world.
