Wireless Sensor Networks has its own importance in different contexts of life such as tracking, monitoring etc. Network Localization is an essential requirement for different wireless sensor network realistic applications. Pilgrim Tracking is one of the realistic application. Tracking large number of people is very difficult process during the season time. The wireless sensor network can be used in such a situation. Localization refers to the self organizing of the sensor nodes with their known positions. This paper presents an efficient modified triangulation algorithm for localization technique which can be used to find the position of the pilgrim having a sensor node in hand. It is fast and simple for implementation in wireless sensor networks for pilgrim tracking. Received Signal Strength Indicator is measured using triangulation method and the mappings of these signals are done to get the estimated position of the unknown node. Positioning is an important factor to find or track the sensor node. Received Signal Strength Indicator from different sensor nodes are compared for estimating the position of the node.
