Performance analysis of Greedy Perimeter Stateless Routing (GPSR) in MANET environment using OMNeT++ for multimedia data communication

MANET has become one of the staple structures of wireless communications and multimedia in the modem era with increasing demand for its services and infrastructure-less nature thatmake every day work a whole lot easier and it uses its well-known and well-used routing protocol suchas GPSR. However, throughout the years, there is a lack of thorough research made on the basic aspectsand performance of GPSR. Even though there are a handful of research papers that has GPSR as the focus of research, however, the testing and experimentation were not too diverse in terms of network performance metrics measured and also the simulation scenarios. This problem leads to limited understanding of the GPSR protocol, thus also limiting the scientific study contribution of the protocol. This research simulated the performance analysis of GPSR in MANET environments, using a network simulator tool called OMNeT++. Simulation results of the GPSR protocol indicate that GPSR has remarkable performance in terms of its average jitter, average end-to-end delay, average throughput, which indicates a good performance when GPSR is routing multimedia data. Besides that, Packet Delivery Fraction (PDF) and also Normalized Routing Load (NRL) is also at optimal results when simulated in various MANET scenarios. For the future work, simulation of GPSR with additional MANET scenarios and network performance parameters can be carried out and different network simulator tool such as Ns-3 can be used in order to gain deeper understanding of the GPSR protocol and to validate or verify the findings of this research.
