Consider a wireless network. For each of the following cases, state whether the packet transmission would be

successful; assume no collision avoidance. Explain your answers.

a$)$ Nodes A and $B$ are in range of each other; no other node is within range. Node A sends a packet to $B.$

b$)$ Nodes A and $B$ are in range of each other; nodes $B$ and $C$ are in range of each other; A and $C$ are not in range of

each other. Both A and $C$ send a packet to $B$ simultaneously.

c$)$ Nodes A and $B$ are in range of each other; nodes $B$ and $C$ are in range of each other; A and $C$ are not in range of

each other. $C$ is transmitting and A wants to send a packet to $B.$

d$)$ Nodes A and $B$ are in range of each other; nodes $B$ and $C$ are in range of each other; A and $C$ are not in range of

each other. $A$ is transmitting and $B$ wants to send a packet to $C.$
