The Internet of Medical Things (IoMT) is a group of internet-connected medical devices used in e-healthcare for remote patient diagnosis, medical equipment regulation, and tracking of quarantined patients. However, the IoMT faces security and privacy concerns due to the vast amounts of data handled by these devices, which can lead to sensitive personal data being exposed to various attacks. This paper proposes a secure route management strategy using the AODV protocol and a modified lightweight AES encryption approach to protect healthcare data. The approach is demonstrated to be secure against black hole attacks and requires relatively low computation and communication resources. These findings indicate that the proposed paradigm is suitable for deployment in IoMT devices with limited.
