In medical telemetry networks, cognitive radio technology is mostly used to avoid licensed spectrum underutilization and by providing access to unlicensed spectrum users without causing interference to primary users, this concept is widely used in development of smart hospitals and smart cities. In medical telemetry networks frequency spectrum concept is used for providing treatment to patients who are far away from hospitals. In cognitive radios, spectrum sensing concept is used in which energy detection method is mostly used because it is simple to implement. While measuring health care environments using cognitive radios probability detection, false alarm probability and threshold parameters are calculated. In this paper for identifying spectrum holes in spectrum sensing using energy detection, distributed diffusion non-negative least mean square algorithm is proposed. It gives better results compared to energy detection concept alone in terms of probability detection converged earlier. If number of nodes are increasing probability detection is decreased from one and move towards left and its SNR is around 1.5-2 dB with proposed method. Hence simulation results give better results in terms of sensing ability while measuring patient condition.

This essay examines the intersections of class, technology, and disability manifest within The King's Speech. It argues that the film obfuscates modern scientific and critical understanding of communication disorders by rendering stuttering as a moral failure rather than by attempting to understand it as a socially constructed condition contingent upon established societal and temporal norms. The essay identifies the social codes enforcing correct and eloquent speech that create a political and social climate for "compulsory fluency"—the socially imperative verbal facility promoted as necessary to participate in public life. Crucially and somewhat ironically, with its emphasis on the nobility of the title character, the film sublimates an inherent tension between media technology and the lingering social stigma surrounding disability. The King's Speech thus situates compulsory fluency as an essential component of modern kingship. By reading the film's strategic deployment of radio technology alongside its troubled representation of class and his fraught invocation of Shakespeare's Hamlet, the essay reads attitudes towards vocal disability within the context of royalty, patriarchy, and national identity. Ultimately, the essay locates The King's Speech as a film whose image of modern kingship grounds itself upon a notion of imperial authority as technologically constructed but ultimately disabled by a national fantasy of historical wholeness in the fabricated kinship between a monarch and his people.
