The Research and Improvement of BEB Algorithm in Wireless Ad Hoc Network

This paper analyses the hidden terminal and exposed terminal problems on MAC layer which increase the probability of data collision and decrease seriously the performance of TCP based on discussing the problem that TCP faces in Ad Hoc network. Through studying the deficiency of the BEB algorithm, this paper proposes an improved BEB algorithm that called AS-BEB. The AS-BEB algorithms can adjust the size of CW based on the current network status. Comparing with the BEB algorithm, the AS-BEB can improve the performance of the TCP applying in Ad Hoc Network.
