Assuring Reliability of Localization Accuracy in Anchor-free Mobile Localization
نویسندگان
چکیده
Anchor-free localization algorithms do not depend on the existence of anchor objects. Since no anchor objects are required, the localization algorithm still can be applied in such problem as difficulty in distribution of anchor objects. In anchor-free localization problem, majority of the solutions need a specific requirement in order to achieve a high accuracy in their localization. In a real environment, it is difficult to maintain such environment. In this paper, we proposed the Distance Sequence for Mobile Localization (DSML) algorithm in order to estimate the position of sensor nodes based on the Receive Signal Strength (RSS) measurements. We exploit the relation of measured distance sequences and mobile beacon’s route to assure the reliability of the localization. We observed that about 89% of selected sensor nodes have improved for about 59% their localization error averagely.

متن کاملOn 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...
