However, this connectivity also makes IoMT vulnerable to cyberattacks such as DoS and Delay attacks , posing risks to patient safety, data security, and public trust. Early detection of these attacks is crucial to prevent harm to patients and system malfunctions. In this paper, we address the detection and mitigation of DoS and Delay attacks in the IoMT using machine learning techniques. To achieve this objective, we constructed an IoMT network scenario using Omnet++ and recorded network traffic data. Subsequently, we utilized this data to train a set of common machine learning algorithms. Additionally, we proposed an Enhanced Random Forest Classifier for Achieving the Best Execution Time (ERF-ABE), which aims to achieve high accuracy and sensitivity as well as low execution time for detecting these types of attacks in IoMT networks. This classifier combines the strengths of random forests with optimization techniques to enhance performance. Based on the results, the execution time has been reduced by implementing ERF-ABE, while maintaining high levels of accuracy and sensitivity.  \nKeywords-IoMT; DDoS attack; Delay Attack; Logistic Regression; Random Forest; Decision Tress; Stochastic Gradient Distance; Naive Bayes.  \nI. INTRODUCTION  \nA cyberattack in the IoMT is a malicious attempt to compromise the security and integrity of medical devices and systems that are connected to the internet. IoMT devices include a wide range of medical equipment and wearable devices, such as pacemakers, insulin pumps, blood glucose monitors, and fitness trackers [1] .  \nA cyberattack in IoMT can have severe consequences, including patient harm, loss of sensitive data, financial losses, and damage to public trust. Therefore, it is critical to implement strong cybersecurity measures to protect IoMT devices and systems from potential threats.  \nA DoS attack includes flooding a system or network with traffic or requests, causing the system to slow down or stop  \nworking entirely. This type of attack can be dangerous in IoMTif it causes a medical device or system to malfunction, potentially putting the patient's health at risk. For example, if a pacemaker is targeted by a DoS attack, it could stop working altogether, which could be life threatening for the patient.  \nA delay attack involves altering the timing of data transmissions between IoMT devices and networks. This can lead to delays in critical information, which could be detrimental to patient care. For example, a delay in transmitting data from a blood glucose monitor to a healthcare provider could result in apatient's blood sugar levels going unmonitored for an extended period, potentially causing harm.  \nDetecting and mitigating DDoS (Distributed Denial of Service) and Delay Attacks is crucial for ensuring the availability and reliability of online services.
