The Primary Task of a Wireless Sensor Networks (Wsns) Is to Sense Theenvironment Around,
Sends the Information Back. the Sensor Nodes Need to Be of Lesssize, Low on Power Consumption Which
Substantially Constrained the Computational Capacityof These Nodes. So any Computational Task
Involving These Nodes Must Be Very Powerefficient So That the Duration of the Deployment Can Be
Increased. In This Paper, We Focus on the Estimating the Position of Unknownsensors Along Higher
Accuracy Lower Power Consumption Using the Information Fromanchor Nodes. It Is As Yet A
Troublesome Issue to Locate a Precise Efficient Node Locationcomputation Algorithm Under Sensor
Networks. This Paper Presents the Literature Review on Dynamicdistance Vector-Hop (Dv-Hop) Method
For Sensor Node Localization to Processing Computing Node Location Along Better Precision Less
Localization Error.
