Nowadays, the advanced technologies of wireless communication significantly increase the attention on Mobile Ad Hoc Network (MANET). This paper aims to improve the routing performance of the large scale and high mobility MANETs. Several routing protocols have been suggested to the MANET and classified as topology and location based protocols. In order to discover and maintain the routes to the destination, topology based protocols require the complete network topology information periodically. Owing to the large number of nodes with recurrent topology changes, it is hard to provide accurate topology information. Large scalability and high mobility factors make vulnerable performance over topology based routing. The routing performance can be enhanced with the aid of location based stateless routing. However, location based routing has to resolve issues such as routing overhead, the duplicate relay, and the packet loss in a void area. To overcome these issues, we propose the Location Based Directional Routing Protocol (LBDR) based on the stateless routing. In the proposed LBDR, the routing overhead is reduced using the Standardized Advance Scheme (SADV). The SADV decides optimal neighbors based on the distance and stability metrics. Together with the Greedy forwarding, the Replica Bound technique (RBT) reduces the duplicate packet transmission over the stateless communication. To overcome the void handling problem, the new idea is coupled with the void handling scheme; it assigns the higher priority forwarding member as the trigger node leads to packet loss reduction. Therefore, it provides a location based solution to the impacts of the network with large scalability and high mobility. The NS2 based simulation results reveal that the LBDR achieves better scalability and efficiency for a large scale and a high mobility network.
