Using Geo-location method for lost node in location based services

The “geo-location” or “location-based services” is an authentication driven system that gives a strong layer in field of lost node localization and that limits the access of information content to specified locations or times with respective to lost node. Yet, the difficulty arises with the GPS related services makes it impractical to incorporate GPS in all the mobile nodes (MN) and subject to availability of GPS signals. The physical location of a particular user or network node at any instant in time is uniquely characterized by a location signature with trace its exact location. These location signature obtain from location node, where several analyst have described how the use of location information can make approach more secured. According to our empirical study the approach can meet the confidentiality, substantiate, clarity, accessibility and practicability of localization of lost node issues in Geo-location authentication systems.
