Modelling a Reliable Multimedia Transmission Approach for Medical Wireless Sensor Networks

ABSTRACT Advancement in wireless and communication technologies has remarkably boosted healthcare services such as Medical WSN. Protecting the patient's health‐related data against malicious activities is also essential. It is mandatory to ensure its dependability and reliability. The reliability of the proposed model in Secure Multimedia Transmission for medical wireless sensor network (IRSMT) system considers the need for authentication and confidentiality in security. Additionally, it enhances the transmission reliability during multimedia data transmission compared to the prevailing methods. To provide reliable multimedia (MM) data transmission, an improved energy‐efficient protocol is considered where the protocol differentiates MM and non‐MM data to enhance routing methodology for MM transmission. The proposed IRSMT enhances adaptability by balancing media quality with prompt delivery and loss tolerance. It is achieved through the anonymous routing method, which maintains the node secrecy using the SHA 256 method. It reduces the probability of data retransmission and provides less processing delay to acquire routing reliability. The simulation results demonstrate the advantages of IRSMT in comparison with the prevailing protocols in performance metrics such as throughput, packet delivery ratio, jitter etc.
