Every sensor node is essential to know their location in the sensor network, even in the presence of malicious adversaries. In that the energy conservation and scalability are critical issues in wireless sensor network. In existing algorithm combines iterative gradient descent with selective pruning of inconsistent measurements to achieve high localization and it can track the mobile nodes with small localization error when nodes are moving slowly. Localization is determining the geographical location of each node in the system.
