Abstract—This paper proposes the Geographic Multicast Fermat Point (GMFP) architecture with an Inside Relay Node (IRN). We use Fermat Point architecture to find the relay Fermat Point node to reduce the distance between received nodes. We also use the Energy-Efficient Beaconless Geographic Routing (EBGR) method to effectively find the optimal relay node position and reduce energy consumption between source nodes and Fermat Points, so that packets are forwarded for all relay nodes. Simulation results show that total energy consumption of GMFP architecture with an IRN outperforms that of GMFP architecture, thereby extending the system lifetime.
