Wireless sensor networks are intended to have large number of sensor nodes which are widely deployed in a distributed environment. Steep increase in number of nodes, which is a deviant to WSN eventually, affects the communication capability of the network as it raises the scalability issue. This at any instance may destabilize network throughput which leads to network failure. Therefore, fault-tolerant protocol is desperately needed to stabilize the dexterity of network. In this paper, the authors have examined the two prominent routing protocols DSDV and AODV which has been the inception for evolution of numerous routing protocols for wireless network environments.
