  The Internet of Things (IoT) has garnered significant interest in both
research and industry due to its profound impact on human life. The rapid
expansion of IoT technology has ushered in smart healthcare, smart devices,
smart cities, and smart grids. However, the security of IoT devices,
particularly in healthcare, has become a major concern, with recent attacks
revealing serious vulnerabilities. In IoT networks, where connected devices are
susceptible to resource-constraint attacks, such as energy consumption attacks,
security is paramount.
  This paper explores the impact of Distributed Denial of Service (DDoS) and
Fake Access Points (F-APs) attacks on WiFi-enabled smart healthcare devices.
Specifically, it investigates how these attacks can disrupt service on victim
devices and Access Points (APs), focusing on device connectivity and energy
consumption during attacks. Key findings include identifying the attack rates
of DDoS attacks that disrupt services and quantifying the energy consumption
impact of Energy Consumption Distributed Denial of Service (EC-DDoS) and F-APs
attacks on smart healthcare devices.
  The study highlights communication protocols, attack rates, payload sizes,
and port states of victim devices as critical factors influencing energy
consumption. These insights provide a comprehensive understanding of IoT device
vulnerabilities in smart healthcare environments and lay the groundwork for
future defense strategies.
