Applying Multidimensional Scaling Method to Determine Spatial Coordinates of WSN Nodes

Abstract

Nowadays, wireless sensor networks (WSNs) are widely used for developing the Internet of Things applications, which provide services such as sensor data collection or monitor, actuator management. In some cases, there are many sensor nodes deployed randomly in the network. In this paper, we consider determining the coordinates of unknown nodes based on the multidimensional scaling method while assuming that the distances between nodes are estimated on the server. However, there are also data gaps about these distances. The article discusses a method for reducing the number of computations required to estimate the distances between nodes.
