Abstract : Mobile Ad Hoc Networks (MANETs) are dynamic, infrastructure-less networks where efficient routing is essential for reliable communication. This network used in various areas like medical, education military etc. In MANET number of routing protocols works for reliable and effective communication. Therefore, we perform experiment and study for different routing protocols. In this work we have taken GRP, AODV, DSDV and OLSR routing protocol. The Geography Routing Protocol (GRP) is a hybrid and location based routing protocol that integrates the advantages of proactive DSDV, reactive AODV routing strategies to achieve faster data transmission and lower control overhead. However, its performance can degrade under varying traffic loads. This paper proposed an adaptive enhancement to the GRP routing protocol that dynamically adjusts location of nodes according to network traffic conditions to optimize packet forwarding and reduce routing overhead. The Performance evaluation is carried out using the NS-3 simulator under different traffic of UDP application.

Keywords : MANET, GRP, DSDV, OLSR, AODV, DSR, PDR, NS-3 Simulator.
