Ad-Hoc networks do not need infrastructures such as a base station and it is an interested technology. One of the important subjects of Ad-Hoc networks is an access control method in radio media. A control channel is usually used with a method of TDMA base. A big influence is given to a performance of Ad-Hoc networks when a frequency channel zone is used as a method of TDMA base. We have already proposed the access control method that is called the Two Division Back off Algorithm (TDBA). This algorithm can solve collisions with a few overheads. But, this method has the problem that the success probability which a node acquires a channel decreases, when the number of the collision-nodes increases. This paper introduces a variable retransmission probability instead of a fixed retransmission probability. And the characteristic of performances is compared and evaluated. Then, as for the point as well that value is made to change, it is examined.
