In bit map protocol, the contention period is divided into N slots, where N is the total number of stations sharing the channel. If a station has a frame to send, it sets the corresponding bit in the slot. So, before transmission, each station knows whether the other stations want to transmit. Collisions are avoided … See more This protocol overcomes the overhead of 1 bit per station of the bit – map protocol. Here, binary addresses of equal lengths are assigned to each station. For example, if there are 6 … See more In adaptive tree walk protocol, the stations or nodes are arranged in the form of a binary tree as follows - See more These protocols combines the advantages of collision based protocols and collision free protocols. Under light load, they behave like ALOHA scheme. Under heavy load, they behave … See more Weba. CSMA/CD b. Polling c. TDMA. a) CSMA/CD: this is a media access protocol.
