We propose a dynamic and distributed CDMA code assignment protocol for ad hoc networks. By combining the RTS/CTS dialogue, modified busy tone signaling and power control Tmechanisms with Tour specially designed CDMA code selection rules, our protocol can not only save precious battery energy of mobile nodes, but also increase CDAM code reusability. Our simulation indicates that the proposed protocol performs better than the static code assignment method and the on-demand code assignment method (with/without using power control) in terms of successful transmission rate, code reusability and number of successful code assignment.
