Intelligent routing protocols became an important scheme to enhance the performance of the routing in Mobile Ad-Hoc Networks (MANETs) also to obtain an efficient operation of these networks by ensuring fast route discovery , fast connectivity , low delay and overhead . This Book presents a novel scheme for MANETs routing protocol known as an Intelligent Ant sense routing protocol (INTANTSENSE). This protocol utilizes a behavior studies of "ants" in nature known as ant colony optimization to perform optimal routing activities . An ant routing concept is a new scheme for routing inspired by the behavior of real ants used in this study. The new protocol (INTANTSENSE) designed and simulated in real MANET environment across a personal area network with IEEE 802.15.4 WPAN and after analysis it displays a satisfactory performances they are optimal path routing, fast route discovery and effective routing failure handling.
