MPDV-HOP:An Improved Localization Algorithm for Wireless Sensor Networks
Authors: ,
Abstract: In wireless sensor network applications,location information of sensor nodes is critical in the life of the entire network.It is a hot issues to design localization algorithm with higher accuracy and lower cost.In this paper,we propose an improved DV-Hop localization algorithm that improves the localization accuracy.The method is based on the traditional DV-HOP, the average hop distance calculation method is further improved and optimized, in the positioning results are looking for optimization of optimal solution, solution here mainly adopts the latest bat algorithm for optimization problems. The experiment result shows that the more the existing positioning methods,MPDV-HOP can effectively improve the average hop distance estimation,and reduce the positioning error.
