Abstract: Security in MANET has been a challenging task ever since the wireless networks came into existence. A number of works have been developed to accomplish this task. Jamming attacks can severely interfere with the normal operation of wireless networks and, consequently, mechanisms are needed that can cope with jamming attacks. This paper introduced the effect of jammer in Mobile Ad Hoc Network and presented how routing protocols can improve the performance of network in terms of some parameters. MANET Routing protocols taken in this study are OLSR ( Proactive routing protocol), DSR (Reactive routing protocol), TORA and GRP (Hybrid Routing Protocol). This study was done using OPNET Modeler (v14.5) in terms of number of scenarios’ parameters for HTTP application such as (Delay, Throughput, Data dropped, traffic received and sent). The results showed that Jammers would reduce the performance by increasing delay and data dropped and decreasing throughput. MANET routing protocols could improve system performance by increasing throughput and data dropped at the expense of increasing delay.
