Final answer:
When a mobile node associates with an access point, it means that the mobile node has established a connection or link with the access point, allowing it to access the network and communicate with other devices.
Step-by-step explanation:
When a mobile node associates with an access point, it means that the mobile node has established a connection or link with the access point. This connection allows the mobile node to access the network provided by the access point and communicate with other devices on the network. The mobile node can send and receive data through the access point, just like any other device connected to the network.
For example, when you connect your smartphone to a Wi-Fi network at home or at a coffee shop, your smartphone is associating with the access point of that network. This association enables your smartphone to connect to the internet and access various online services.
