This paper, presents typical routing protocols based on unicast or multicast routing schema selected from the class of similar approaches that can reflect the state of- the-art of research work on mobile ad hoc network routing. Proactive, reactive and hybrid approaches have been used in every of the unicast routing protocol and multicast routing protocol classification. Wireless communication technology has been developed with two primary models ─ one is fix infrastructure based model in which much of the nodes are mobile and connected through fixed backbone nodes using wireless medium. Another model is mobile ad-hoc network. Mobile ad-hoc Networks (MANETs) are comprised of mobile nodes (MNs) that are self-organizing and cooperative to ensure efficient and accurate packet routing between nodes and potentially base stations. There are no specific routers, servers, access points for MANETs. Because of its fast and easy deployment, robustness, and low cost, Typical MANETs applications can be found in the following areas like military applications (a temporary network in the battlefield), search and rescue operations, temporary networks within meeting rooms, airports, vehicle-to-vehicle communication in smart transportation, Personal Area Networks connecting mobile devices like mobile phones, laptops, smart watches, and other wearable computers etc.
