【Abstract】In the past decade, blockchain has successfully shown its significance in providing a secure platform for two-way exchange of data. Similar to this, the Software Defined Wireless Body Area Networks (SDWBAN) have grown more popular since they make network administration a simpler process. Healthcare administration services can be substantially improved by integrating SDWBANs with medical facilities. However, sharing sensitive information among multiple stakeholders in the healthcare sector is challenging due to several issues, including confidentiality and integrity. Hence, it is important to address the variety of limitations in the traditional SDWBAN technique when exchanging highly private data. Here, an innovative model is proposed for secure data sharing in the SDWBAN. In the SDWBAN model, blockchain is employed to secure sensitive information. Next, the access control for the blockchain model is offered by considering the New Consensus Algorithm based on the Optimal Members and President Election (NCA-OMPE) procedure. In this phase, required members are selected optimally using Upgraded Candidate Position-based Magnificent Frigatebird Optimization (UCP-MFO) by considering various objective functions like efficiency, scalability and Transaction Processing System (TPS). Next, the president is elected by the optimal members and also the current optimal members stand for the next presidential election. Further, the Elliptical Curve Cryptography (HECC) technique is employed to encrypt the data presented in the blockchain while data-sharing procedures are performed. Finally, several validations are employed in the proposed approach with various conventional techniques to verify its performance. Here, the designed approach has an encryption time of 0.90 (s) and a decryption time of 0.62 (s) in terms of block size as 20. Thus, the overall performance outcomes showed that the proposed approach's superior performance, thus it helps to allow faster data transfer with better security, when dealing with high-dimensional healthcare data. Also, it enables a better data sharing process for minimizing unauthorized access and attacks.
