SHAKTI — Secured and highly adaptive knowledge base tracking information system using android platform

Abstract

In the present day scenario security of people is a big issue. Moreover natural disasters occur very often nowadays. In this respect there should be some mechanism by which any person falling into a crisis, can inform about the emergency situation to other person(s) of her choice to seek help. This paper presents a system which deals with the issue of emergency and crisis situations. The system enables a fully automated location tracking mechanism by which a user's present location can be tracked. The system allows dynamic switching between different location tracking strategies of the Android platform depending upon the prevailing conditions. The tracked locations are periodically updated to server or sent to emergency contact numbers as and when required. We present an algorithm to minimize the energy consumption of the system for location tracking and show significant reduction of power consumption by as much as 93.4% (approx).
