Now -a-days health problems has been a major concern and monitoring the patients has become a significant part of various healthcare services. If the vital signals such as blood pressure, ECG, pulse and blood oxygenation of patients are disseminated to the physicians or doctors in real time then the likelihood of saving the patient’s life considerably increases. Thus in this paper VANET technology has been exploited to collect data from the patients and transmit it to the final destination. Here, a hop scheduled data dissemination algorithm has been proposed to disseminate huge amount of medical data to hospitals. Prior to transmission, the medical data are encoded with transmission frequency using polynomial function to allow efficient transmission. Simulations are carried out to analyze the effectiveness of the proposed approach.
