Modern developments in the field of micro-sensor devices have enhanced research and developments in the sensor networks leading to many new protocols are being designed especially for Wireless Sensor Networks (WSNs). Wireless sensor networks with hundreds to thousands of sensor nodes can collect data from different location and transmit the collected data to a particular user, depending on the application and its requirements. These sensor nodes have some constraints due to their limited energy, storage capacity and computing power. Information is routed by various routing protocols from one device to another device. Wireless Sensor Network is a challenging network in which communication between nodes is unpredictable and difficult. This demands the performance analysis of different routing protocols to find out a protocol which more suitable for a particular scenario. This Research will present the performance evaluation of reactive (AODV, DSR) and proactive (DSDV) routing protocols in WSNs by varying parameters like node density, node speed and pause time for TCP and UDP traffic patterns. Under different network scenarios and Mobility models, these routing protocols will compare using widely used performance metrics such as packet loss, end-to-end delay and throughput.
