What is a method to confirm the presence of a hidden node on the network?

The method to confirm the presence of a hidden node on the network is through the use of the Request to Send/Clear to Send (RTS/CTS) protocol. This protocol is designed to alleviate collisions in wireless networks, particularly those occurring due to hidden nodes. When a device wants to send data, it first sends an RTS signal to the access point, which can help prevent data collisions by ensuring that only devices that are ready to receive the data will do so.

By enabling RTS/CTS, the access point coordinates the communication between devices more effectively. If a hidden node exists, it may not be aware that a transmission is occurring, leading to potential data collisions. However, with RTS/CTS active, devices are required to check in before sending data, which helps reveal whether any other devices are transmitting and confirms the presence of hidden nodes in the vicinity. This capability to manage transmission timings makes RTS/CTS an effective method for identifying and confirming network issues related to hidden nodes.

While the other options could be relevant in different contexts, they do not specifically target the identification of hidden nodes. Analyzing signal strength can provide information about signal quality but doesn’t directly reveal hidden nodes. Checking for firmware updates can improve network performance but does not
