Question 3 [15] a) List 3 pairs of devices that connect between each other by Bluetooth communication. [3] b) Consider the following network topology (See Figure 3 below): 2 v 1 u 2 2. 3 3 2 w 3 Figure 3. Network topology diagram Construct the stepwise Dijkstra's table, forward table from u and shortest path tree from u (to any nodes) for the network topology diagram of Figure 3 using the Dijkstra's Algorithm.
