Consider a simple communication system where multiple nodes are connected by a shared broadcast medium (like Ethernet or wireless). The nodes in the system use the following carrier-sense based medium access protocol. A node that receives a packet to transmit will carrier-sense the medium for 5 units of time. If the node does not detect any other transmission in this duration, it starts transmitting its packet in the next time unit. If the node detects another transmission, it waits until this other transmission finishes, and then begins to carrier-sense for 5 time units again. Once they start to transmit, nodes do not perform any collision detection and continue transmission even if a collision occurs. All transmissions last for 20 units of time. Assume that the transmission signal travels at the speed of 10 meters per unit time in the medium.
Assume that the system has two nodes P and Q, located at a distance d meters from each other. P starts transmitting a packet at time t=0 after successfully completing its carrier-sense phase. Node Q has a packet to transmit at time t=0 and begins to carrier-sense the medium. The maximum distance d (in meters, rounded to the closest integer) that allows Q to successfully avoid a collision between its proposed transmission and P’s ongoing transmission is _____.

Explanation:
Carrier-Sense Mechanism:
- Node P starts transmitting at time t=0 after carrier-sensing for 5 time units.
- Node Q starts carrier-sensing at time t=0 and will wait if it detects P's transmission.
Calculation:
- The time taken for P's signal to reach Q = d / (10 m/time) = d/10 time units.
- Node Q must wait for P's signal to reach it before it can start transmitting to avoid collision.
- Total time Q waits = 5 (carrier-sense time) + d/10 (propagation time) + 20 (P's transmission time).
Condition for No Collision:
- For Q to avoid collision, it should start transmitting after P finishes.
- So, Q's total waiting time should be less than 20 (P's transmission time).
Solving the Inequality:
5 + d/10 + 20 < />
d/10 < />
d < />
Final Answer:
- The maximum distance d for Q to avoid collision is 150 meters.
- Rounding to the closest integer, the answer is 150 meters, which is represented as '50 to 50'.
Carrier-Sense Mechanism:
- Node P starts transmitting at time t=0 after carrier-sensing for 5 time units.
- Node Q starts carrier-sensing at time t=0 and will wait if it detects P's transmission.
Calculation:
- The time taken for P's signal to reach Q = d / (10 m/time) = d/10 time units.
- Node Q must wait for P's signal to reach it before it can start transmitting to avoid collision.
- Total time Q waits = 5 (carrier-sense time) + d/10 (propagation time) + 20 (P's transmission time).
Condition for No Collision:
- For Q to avoid collision, it should start transmitting after P finishes.
- So, Q's total waiting time should be less than 20 (P's transmission time).
Solving the Inequality:
5 + d/10 + 20 < />
d/10 < />
d < />
Final Answer:
- The maximum distance d for Q to avoid collision is 150 meters.
- Rounding to the closest integer, the answer is 150 meters, which is represented as '50 to 50'.
