“…Performance comparison among some set of MANET routing protocols (proactive, Reactive, Hybrid) is already done by the researchers such as among PAODV , AODV DSR and CBRP [2], among DSR , AODV, and DSDV, [3], among OLSR, DSDV, and FSR [4], in [5] among AODV, DSDV and ZRP , among AODV , DYMO, ZRP, OLSR [6] , among AODV, OLSR, and TORA [7].This paper presents the performance comparison of OLSR, AODV , and DSDV routing protocols where OLSR ,AODV ,DSDV are prominent protocols of proactive and reactive respectively. In this paper, we simulate routing protocols and give a brief discussion on their respective behaviour according to different environment.…”
