A Method of Improving WSN Localization Algorithms Based on Hopsize Deviation
نویسندگان
چکیده
This paper analyzes the DV-HOP algorithm which is a range-free localization algorithm. We improve this algorithm by revising the hop-size. In our method, uniform distribution model and secondary reference nodes are introduced to localize the unknown nodes. In addition, the hop-size of the nearest hop is used during the estimation of the distances between the beacon nodes to the unknown nodes. Simulation results show that this improved algorithm could achieve higher localization accuracy compared with original method. Copyright © 2014 IFSA Publishing, S. L.

On improving APIT algorithm for better localization in WSN
In Wireless Sensor Networks (WSNs), localization algorithms could be range-based or range-free. The Approximate Point in Triangle (APIT) is a range-free approach. We propose modification of the APIT algorithm and refer as modified-APIT. We select suitable triangles with appropriate distance between anchors to reduce PIT test errors (edge effect and non-uniform placement of neighbours) in APIT a...
