Consider an unweighted and undirected wireless network, as shown in Figure 6.18 in the text book (reproduced as Figure 6.1 of this solution manual). Identify the nodes with the highest wireless flow betweenness. What are the impacts on the resources of the nodes with high WFB?

What will be an ideal response?

A node with high value of WFB resides in most of the shortest paths in a network. Therefore,

an LL created with a node with higher WFB improves APL value of the network. However,

creating an LL also results in increasing number of end-to-end shortest paths through that

node. As a result, the node becomes congested and turned into a bottleneck node in the

network. This will introduce more transmission delay in the network. Hence, the node with

the higher WFB values should be used wisely in order to enhance overall network throughput.
