Nature is a great inspiration source for solving different kinds of problems. It provides some efficient ways to solve real world optimization problems. This book illustrates the study on some swarm intelligence based naturally inspired algorithms and describes how the foraging behavior of ants, swarm of birds, honey bees and bacteria are used in solving the optimization problems Ad Hoc Networks. It also includes evaluation on the performance of bio-inspired hybrid algorithms in the field of Mobile Ad Hoc Networks. The evaluation result shows the efficiency of bio-inspired hybrid algorithms...
