In this paper, we propose a new Contention Access Protocol (CAP) augmented with a Dynamic Bandwidth Allocator (DBA) for wireless ATM networks supporting ABR and Signaling Control (SCR) traffic. CAP incorporates a dynamic tree-splitting collision resolution algorithm parameterized by an optimal Splitting Depth (SD). DBA performs estimation and on-line prediction of ABR self-similar traffic characteristics. It in turn determines the optimal SD per every frame, satisfying ABR throughput and SCR blocking probability requirements while retaining maximal aggregate throughput. Simulation results postulate the optimal SD's under various ABR and SCR traffic conditions. These results are then off-line trained and constructed by a Back Propagation Neural Network (BPNN), which is used on-line for optimal bandwidth allocation.
