An Enhanced Cooperative Localization Strategy for Emergency-WSN

Various fields use wireless sensor networks, including disaster management, industrial security, wildlife tracking, and the military. The location of the Node is crucial for many tasks. Numerous issues with location management exist, including the number of anchors, energy use, and location accuracy. Most current location management techniques increase the sensor node’s location accuracy by employing multiple anchors, more bandwidth, energy, and computation space. A significant loss of energy and time occurred to determine the positioning of each sensor node. Estimating the locations of every sensor in a sensor network in many applications is unnecessary. An official description, design, and implementation of a cooperative localization algorithm are presented in this paper. Instead of locating the entire network in WSNs, there is a need to locate only a specific set of sensors. The network becomes unfussy when only a few sensors do event detection, a few are mobile, and only a few are recently attached. This protocol’s primary objectives are to increase location accuracy with fewer anchors by using virtual anchor concepts and to calculate the coordinates using new trilateration techniques.
