Question

Suppose five stations A, B, C, D, and E are in a wireless network with the following configuration:

See attached for the rest --> please add explanation while answering

- B, C, D, and E are in A’s range
- A, C, and E are in B’s range
- A, B, and D are in C’s range
- A, C, and E are in D’s range
- A, B, and D are in E’s range

**Task:**
Give an example of a hidden terminal problem and an example of an exposed terminal problem that could happen in the wireless network.

Expert Solution

Step 1

Provided Data:

In the A set, B, C, D, and E are

In the B range, A, C, and E are

A, B, D in the spectrum of C's

In the D range, A, C, and E are

A B and D are within the range of E

If it is considered stations B, C, and D, C is visible to B and D, but C is not visible to B and D.

The figure above indicates that station B is beginning to transmit to station C. Since station D is not within the B range, it believes the channel is free and starts transmitting to C. The frames obtained by STC are garbled and there is a collision. The secret terminal issue is called this condition.
