Mobile ad-hoc network is widely used in various communications due to its easier deployment and cost effectiveness. In recent technological advancement, Manet is used in all types of environment including pervasive computing, Internet of Things, military applications, Disaster recoveries, Vehicle tracking etc. In Manets, the research is going on in the field of Routing such as Hierarchical routing, Zone based routing, Distance based routing etc. Manets in case of sensitive networks has to face the challenge of security and in many cases the existing protocol is enhanced with security using cryptographic techniques. In recent researches, Soft computing techniques like Genetic Algorithm, Fuzzy logic, Neural Networks are employed in Manets in every area of research. We propose an attempt to survey the applications of soft computing techniques in Manet and in particular Artificial Neural Network learning technique. Since Soft computing techniques are efficient for solving complex problems, our focus is towards this survey approach in Manets.
