The expansion in information technology and the need for large scale communication infrastructures has triggered the area of Wireless Sensor Networks (WSNs). Network is a collection of wireless nodes these are communicates with each other without using any offered infrastructure, access point or centralized administration. Wireless sensor networks may consist of hundreds or even up to thousands of small dense devices, equipped with sensors (e.g. acoustic, seismic or image), that form a wireless network. Each sensor node in the network collects information from its surroundings and sends it to a base station, either from source sensor node to destination sensor node, i.e. multi-hop, or directly to the base station. This paper presents performance comparison of four popular wireless sensor network routing protocols i.e. Dynamic Source Routing (DSR), Optimized Link State Routing (OLSR), Fisheye State Routing Protocol (FSR) and Location - Aided Routing (LAR) in variation of nodes and random waypoint mobility. We used well known network simulator QualNet 5.0 from scalable networks to evaluate the performance analysis of above protocols. The metrics used for performance analysis of End to End delay (s), Average Jitter (s), Power consumption in receive mode, transmit mode, idle mode and battery consumption.
