Evaluating the performance of WCDMA wireless networks is important because it allows determining the types of applications that can be supported on such networks. BER of an average multi-hop route directly affects the ability of wireless network to support applications requiring a specific BER, for a given node transmission power and node spatial density. Given this feature, destination node can estimate stability of routes and can select the best and more stable route. Therefore we can reduce the delay and jitter of sending data packets. In this work, an attempt has been made to compare the performance of two prominent on demand reactive routing protocols and one proactive routing protocol for WCDMA scheme & these protocols are DSR, DSDV & AODV protocols. DSR and AODV is a reactive gateway discovery algorithm whereas DSDV comes under proactive category. A WCDMA scheme connects by gateway only when it is needed. our simulation results for all the three protocols based on metrics such as packet delivery rate, throughput, routing overhead and average end to end delay by using NS-2 simulator.
