In Mobile ad-hoc networks (MANET) with high number of nodes and high mobility the routing of packets is a difficult task. In this paper, we are reviewing different geographic routing protocols as geographic routing are efficient for highly mobile nodes and made the communication scalable. Different protocols compared are The Distance Routing Effect Algorithm (DREAM), Location Aided Routing (LAR) Calculation, Greedy Perimeter Stateless Routing(GPSR) as of late new convention comes which is exceedingly proficient is the Adaptive position update (APU) strategy and further the improved APU strategy and on the basis of performance metrics the protocols are compared and reveals that the Improved APU strategy gives the high packet delivery ratio, lower delay and low energy consumption.
