In this paper, we propose an efficient algorithm of quick routing for private Wireless ATM (Asynchronous Transfer Mode) networks. This algorithm uses hierarchical source routing, which first establishes a connection between the sending node and the home node (which has the terminal location information), and then, partially releases the connection and reroutes it between the sending node and the receiving node. This results in less delay than found in other conventional routing methods, and avoids passing through congested nodes, because this algorithm uses traffic estimation based on queuing theory. We also show the effectiveness of this algorithm with the use of computer simulations.
