Obstacle based Range-Free Localization-Error Estimation for WSN

The projected paper considers a range-free localization protocols for the wireless sensor networks that highlights the localization irrationality problem in presence of obstruction. Here in our proposed research work the mobile anchor node is assumed to have the evidence of their position where an interaction protocol is considered. The proposed enables the presence of relay nodes with the beacon signals for the better optimization techniques by using the coordination ordinary sensor nodes and mobile anchor nodes simultaneously. The impediment consequence in the form of obstacle were studied with the transmission irregularities with the radical change algorithm for computation the localization errors in the range free localization. The significance of the current work considers the diversification of Sensor network topology. The performance analysis executed in various scenarios and our model was compared with DV-Hop, APIT, ROCRSSI, and Amorphous techniques. A simulation result in comparison with the existing system projected outperforms for minimizing localization error even in presence of obstacle.
