## 5 Conclusions and Future Direction  
The attaining of good health facility and security of electronic medical records is the most demanding need for mankind, and thus, the WHO emphasized on the fundamental rights of human beings to attain quality healthcare. In recent times, the healthcare system is experiencing transference from a traditional approach to a modernized patient-oriented approach. In a modernized patient-oriented approach, the implementation of the information technology for the exchange of patients' personal data with ease of communication is in the interest of an individual's health through telemonitoring and telemedicine systems. Keeping in view all associated advantages, telemonitoring has been recognized as a promising area of research by using the latest tools to transform raw data into useful data. In WBAN, avoiding overheating of the nodes and energy preservation are the two most vital features need to consider for the stability of WBAN. Considering the unique essence of WBAN along with the routing and security issues, a blockchain-enabled routing protocol ATEAR and its improved version Enhanced ATEAR is presented in this work. To testify the significance of the presented protocol, several experiments on the basis of temperature, energy, latency, and throughput are carried out. The results generated from the simulations are compared with the existing routing technique MRRP. The results show a better performance of ATEAR and Enhanced ATEAR than MRRP, TARA, and SHR. The demonstrated results show the temperature rise and energy depletion in MRRP is impracticable for WBAN. Moreover, the proposed blockchain-enabled WBAN platform is based on the network and resolve the existing challenges of WBAN, i.e., scalability, identity, and data security.

Table 5: Resource use analysis of proposed system. Temperature and energy, on the other hand, didn't cause any damage to the tissues due to the fact that the threshold always lies within the threshold. Additionally, the overall performance of the enhanced ATEAR is improved due to energy harvesting and temperature thresholding. The throughput is also considerably improved in the proposed work than in MRRP, TARA, and SHR due to the even distribution of energy and temperature The presented protocols are for fixed implanted sensors with no mobility. Regarding our future work, we are planning to extend the proposed protocol to deal with the different body postures, i.e., the postural movement of the body will be considered along with the maintained temperature and energy of the network.
