1. If a wireless node receives a stronger signal from Router 1 than Router 2, should the node use Router 1 as its path to the Internet? Explain.

2. When a border router uses RPL, what information does the border router collect?

3. Suppose a ZigBee mesh node sends an IPv6 datagram to another mesh node. What path does the datagram take? (Hint: consider the information that an individual node keeps.)

4. Does each node in a ZigBee mesh network need a complete IP forwarding table? Why or why not?
