This paper presents a literature review on WSN networks, in which the capacity of network nodes is limited with respect to energy supply, restricted computational capacity and communication bandwidth. WSN is a complex set of applications, link technologies, communication protocols, traffic flows and routing algorithms. Simulation is a predominant technique used to study and analyze the performance of a wireless senor network design. To prolong the lifetime of these sensor nodes, designing efficient routing protocols are critical. Basically, the Routing protocols for wireless sensor networks are responsible for maintaining the routes in the network which ensures reliable multi-hop communication. To address this issue, in this paper, various protocols like AODV (Ad-hoc on-demand distance vector routing), DSDV (Destination-Sequenced Distance-Vector Routing) and ZRP (Zone Routing Protocol) are discussed along with various comparative parameters like Throughput, Packet Loss Ratio, End to End Delay and Dropped Packets. The performance of these protocols varies depending on the simulation environment. It will be analyzed in two ways. Firstly, by varying nodes within a margin of 10 to 100 nodes. Another way is by keeping the number of nodes constant and varying the speed of nodes from 10 m/s to 90 m/s.
