Abstract: A network topology is the design of connections which includes nodes and links. When the nodes change their positions, the topology either increases or decreases and hence methods for obtaining the maps that preserves the topology from the virtual coordinates is presented. Firstly Received Signal Strength(RSS) technique which relies on frequency parameter for distance calculation between the nodes is presented. Next another approach known as Location Aware Routing Technique (LART) which relies on latitudinal and longitudinal values for the distance estimation is presented. Lastly the proposed approach of DALD (Distance based Attack Localization and Detection) which is a counter measure to restore/ preserve the network region and a methodology to overcome the disadvantages of the existing frequency based approaches is implemented. The proposed T&S mapping (Track and Sector) based user check maintains a record of the communicating nodes which tracks the sector in which the node lays. It improves the communication by avoiding hidden node problem which distorts the mapping co-ordinates and other malicious access in the network path. Besides, the AOD (Angle Of Deviation) improves the accuracy of detection and localization based on angular presence verification on each and every transmission, allowing secure nodes to communicate, minimizing the anonymous distortions in the network mapping.
