Sensor node localization is considered to be one of the most critical issues in a Wireless Sensor Network (WSN). The objective of localization is determination of physical co-ordinates of a group of sensor nodes. The location information plays a vital role for coverage, deployment of sensor nodes and rescue operations. Many applications such as routing and target tracking are all location dependent. This paper aims at determining the location of the sensor nodes with high precision. The initial part of this work is carried out by localizing the nodes using Mobile Anchor Positioning (MAP), a range-free localization method.
