The main objective of this paper is to design and implement a reliable system to protect women from being harassed by providing last mile connectivity even in situations where the mobile phones are out of cellular coverage. In this paper we have developed a prototype for women safety by using radio identification based cognitive radio, GSM/CDMA mobile communication and global positioning system (GPS). The system will identify the location through GPS when a women activates her mobile phone either by a click or press of a button for few seconds before she outrages any incident and sends a message comprising the location URL to the registered contacts and also a recorded call message on the first registered contact to help the women in dangerous situations. The unique feature of this system is that it continuously sends message for every two minutes till the application is stopped. Continuous location tracking information via SMS helps to find the location of the victim quickly and rescue them safely. Extensive simulation work is done using NS2 simulator to validate the performance of the system.
