It is a common misunderstanding that bandwidth is assigned to individual nodes. In the wireless setup you only define the transmission speed of the node. Wireless communication uses a shared medium and so a node has to share the channel access with all nodes that are within interference range. Additionally you should keep in mind that a message from one node to a target multiple hops away probably consumes bandwidth multiple times - just as an example, a message consumes bandwidth at the node when the node transmits the message, and when the neighbor and most likely the 2-hop neighbor forward it towards the destination.
btw - this question has been asked multiple times before on this list. Regards, Daniel.
