P13. Consider a broadcast channel with N nodes and a transmission rate of R bps.

Suppose the broadcast channel uses polling (with an additional polling node)

for multiple access. Suppose the amount of time from when a node completes

transmission until the subsequent node is permitted to transmit (that is, the

polling delay) is dpoll. Suppose that within a polling round, a given node is

allowed to transmit at most Q bits. What is the maximum throughput of the

broadcast channel?
