A local area network operates Ethernet with CSMA/CD mechanism and runs at a transmission rate of 8 Mbps and a one-way signal propagation time of 25 microseconds. How long has a station to wait before trying to access the channel again, after experiencing 5 successive collisions?

1. 125 microseconds.

2. 625 microseconds

3. 800 microseconds

4. 1600 microseconds.

After 5 collision k= {0 ….. 2^5-1}

RTT= 50 µsec

Maximum waiting time = 31×50 µsec=1550 µsec ≈ 1600
