    A group of stations share a 16 kbps slotted Aloha channel. Each station outputs a 80 Bytes frame and buffers any outgoing frames until they can be sent. Collectively (recall that this means original frames plus resending of frames that suffered a collision previously) the stations attempt to send 30 frames/sec. What is the throughput in frames/sec?

    Available bandwidth = 16kbps = (16/8) kBps = 2 kBps
    Size of each frame = 80B

    Since a frame is synonymous with a time slot in slotted Aloha protocol,
    number of ...
