For what purpose the binary exponential backoff algorithm is used
Answers
Answer:
☑ Binary Exponential Backoff (BEB) refers to a collision resolution mechanism used in random access MAC protocols. This algorithm is used in Ethernet (IEEE 802.3) wired LANs. In Ethernet networks, this algorithm is commonly used to schedule retransmissions after collisions.
The binary exponential backoff algorithm is used to prevent packet collisions during simultaneous access.
By randomizing moments at stations attempting to access wireless channels, the Binary Exponential Backoff Algorithm eliminates packet collisions during simultaneous access. However, because this randomization does not completely avoid packet collisions, system throughput is diminished and packet delay and drop increase. In addition, the BEB Algorithm causes stations to have unequal access to channels.
