New routing algorithms are being developed to reduce power consumption, effective utilization of resources and best route to a specific destination, to name a few, in wireless mobile ad hoc network. To simulate the algorithm, interaction between the different layers of the OSI, the link available and furthermore, employing a suitable propagation model in a wireless environment, the use of network simulators do eliminate irrelevant issues pertaining to the actual work which is testing the algorithm. This paper presents the development of the simulation program to test a new routing protocol called quadrant-based directional routing protocol (Q-DIR). Q-DIR uses exact location of nodes based on Cartesian-coordinate system to restrict the broadcast region to only a quadrant where the destination node and source node are located.
