Abstract

Recently, wireless transmission of medical data of the patients in heterogeneous networks evoked keen interest among researchers. However, the challenges such as efficient utilization of the frequency spectrum, increase in the lifetime of the devices are considered to be the most important issues nowadays. In this project, while considering the above mentioned challenges for an efficient use of medical devices among the patients, design of cognitive radio network has been incorporated, along with the Hospital Management System. The proposed paper developed a new algorithm/network called Bio Cog—for the implementation of the cognitive networks for transmitting the medical data, which uses efficient frequency spectrum allocation method. The energy efficiency has been achieved by incorporating new algorithm (D2V algorithm) in cognitive networks. The proposed system uses the principle of novel spectrum sensing techniques in the wireless cognitive radio networks. In this research, heterogeneous network has been taken into account by working with different wireless technologies such as XBee, Wi-Fi and Bluetooth and accordingly, different frequency bands are allocated. When the spectrum is sensed by the designed hardware, it decides on allotting the vacant band to the specified users. All users are connected with temperature sensors whose temperature is measured continuously based on which the users are given priority in allotting the spectrum. Thus the hardware can be used in medical applications and tested for one such application called Hospital Management System which is developed and implemented in this work. The hardware has been designed to implement the Dynamic Distance Vector Algorithm (D2VA) in which the distance plays an important role in deciding the threshold range for sensing.
