Over last year the rapid growth in wireless network application has encouraged to improve the network service performance. MANETs have become very popular due to growing popularity of mobile device. This network does not have certain topology i.e. it has infrastructure less network. Because of its frequent topology changes and routing overhead, routing protocol in MANET has become one of the challenging issues. Many routing protocols have been proposed so far. Performance of these protocols has been tested for general traffic under CBR traffic with varying network condition. CBR traffic does not reflect the complex nature of traffic in real applications and these traffic scenarios are more representatives of network loads placed on a real world MANETs. In this paper we conducted number of simulation in order to evaluate the performance of four routing protocols OLSR, AODV, LAR1, ZRP for CBR traffic in terms of packet delivery ratio, throughput, jitter, end-to-delay in realistic condition. Various network scenarios are considered like effect of varying node and effect of varying in pause time. The simulations are carried out in Qualnet simulator6.1.
