Abstract

Objective: This paper deals with the proposed Dynamic DV-Hop technique for wireless sensor node localization is used for the computing node location with better accuracy and less localization error. Method: DV-Hop is simply an algorithm of the range-free localization which can help us getting estimation by using the hop-distance. Since there is very low location accuracy found in DV-Hop localization algorithm. By figure-out the DV-Hop problem so it is essential improving the DVHop algorithm, a newly and the communication ranges. This method requires no extra supplementary estimated model is propounded by considering the relations in between the node-hop distance hardware support. However, this method can be instrumented in a distributed manner. Findings: The simulation work show that the proposed scheme decreases the total communication cost than the normal DV-Hop algorithm so in the proposed Dynamic DV-Hop method it represents less localization errors which is established by the graphs. In the present study, proposed scheme provides efficient energy utilization and management during the Dynamic DV-Hop localization method. Application/Improvement: The research work concludes by stating that very low location accuracy found in DV-Hop algorithm but this issue can be improved by proposed Dynamic DV-Hop algorithm and efficient energy utilization and management is performed.
