The advancement in communication technology and the need for large-scale communication infrastructures has triggered the era of Wireless Sensor Networks (WSNs). In this Project we are analyzing the performance of Proactive, Reactive and Hybrid routing protocols on robust conditions to check the Quality of Service (QoS) metrics like Packet Delivery Ratio, Throughput, end to end delay and Jitter in the Wireless Sensor Networks. Multipath fading heavily contributes to the unreliability of wireless links; the impact of fading on wireless sensor networks is considerable. In this paper focus is given on studying the performance evaluation of various routing protocols using Qualnet simulator 7.1.4. The performance of the proactive, reactive and hybrid protocols are analyzed with different nodes over gaussian fading channel. The metrics used for the performance evaluation include jitter, throughput, packet delivery ratio and average end to end delay.
