Cognitive Radio for emergency and public safety applications/wireless medical networks.

Cognitive radio, which is also referred to as dynamic spectrum  access technology or agile radios that automatically find and access un-used spectrum across different networks (licensed and un-licensed  including the features of optimization and adaption)  can be beneficial when all source of the communication are affected. Currently some companies are working on implementation of

cognitive radios that will work on TV broadcasting bands in order to use the white space that is not of any use in the frequency spectrum of the TV transmission channel, such type of developments are expected to bring beneficial methodologies and solutions to the problems of public safety and emergency case communications, especially related to interoperability issues[2]. However, wide range of opportunities introduced by the awareness, learning and intelligence features of cognitive radios necessitate the reassessment of opportunities to the public safety and emergency case communications from a more complementary aspect. One aspect can be the development of applications that will lead to communicate, locate and reach victims who are stuck in harassed condition one of them may be psychosocial risks of cardiovascular disease we integrated on-the-body sensors with mobile therapies for "just-in-time" stress management. Breathing visualizations and cognitive reappraisal cues appeared on the cell phone when a wireless ECG detected deviations from an individuals' baseline heart rate variability. Reactions from participants validated this concept and highlighted the need for a broader array of therapies and applications that could be shared within relationships and communities. Now this strategy can be made marvelous if we think of implementing an [4] intelligent software agent whose work is to output the data in audio signal so that the use of the device became more easy. [1]

As we see above a how with the help of cognitive radio the woman can check her mood ,the mechanism behind the whole process is that the woman fixes   A wireless ECG detector on her body near heart which  detects changes in stress levels as measured by deviations in heart rate variability and triggers mobile therapies and as a result she get the result in the audio form. This audio output methodology can be implement on various aspect of our day to day life and during the emergency and public safety applications like in forest fire, hurricane etc. This is like, we are communicating with a device and it is replying what we desire. This can may be consider as a substitute for the apple ‘siri’ but we can’t incorporate it completely as it is not possible to have a data connection everywhere. Adding voice channels to the cognitive radio revolutionaries the whole concept and reform it into an intelligent device. So in this paper we will study how the voice option helps the cognitive radio in order to excavating from the problems of the public safety.
