Consider the following MAC protocol for single$-$hop broadcast$-$and$-$select networks: $\text{'}$It assumes that each node transmits on a unique fixed wavelength, different from the other nodes, and uses a tunable filter to select one among all the different wavelengths for reception. In addition, there is a control channel shared by all the nodes, in which each node is assigned a time slot for transmission. A node transmits the packet header in its assigned time slot on the control channel and follows this by transmitting the actual packet on its data channel. After listening to the packet header on the control channel, the intended receiver tunes to the appropriate channel to receive the packet.$\text{'}$ Can collisions occur here? Suggest a way to deal with destination conflicts.
