College of Science for Women, University of Babylon discussed a master dissertation on determining locations in wireless sensor networks based on graph theory and received signal strength indicator methods by the postgraduate student, Mrs. Zainab Iyad Hamidi.

The dissertation aimed at presenting an innovative approach to localize node coordinates within WSN networks, this approach uses graphs and Received Signal Strength Index (RSSI) measurements to estimate the distances between each sensor node and its neighboring nodes in the target field and the central sink node Sink collects information to create the network graph and estimate the exact locations of nodes.

The dissertation highlighted that obtaining accurate information about the location of nodes is essential for many wireless sensor network (WSN) applications, including location-based routing, tracking systems, dynamic networks and health monitoring systems.

The dissertation reviewed the effectiveness of this approach and enhancing location accuracy while reducing errors compared to the existing data.
