CSMA--Energy Level-- We can say that the level of energy in a channel can have three values. Zero, normal and abnormal. At the zero level the channel is idle. At the normal level a station is successfully captured the channel and is sending its frame. At the abnormal level there is a collision and level of energy is twice the normal level. A station that has a frame to send or is sending a frame needs to monitor the energy level to determine if the channel is idle,busy or in collision mode.
