本文探讨了在存在隐藏终端干扰的CDMA无线自组网中，针对网络拓扑变化提出了一种新的簇划分算法和动态代码分配方案。算法旨在提高代码资源的有效利用并保持对网络动态性的适应性，解决了传统CDMA在adhoc网络中的代码更新难题。
摘要：
Wireless ad hoc networks provide a new dimension to computing by allowing a group of portable devices to talk to each other without any additional infrastructure and have been the focus of research in the area of wireless networks. CDMA has been gaining popularity as the multi-access technique and is part of many wireless standards now. In a CDMA based system, users are assigned different "signature wave forms" or "codes". A problem in using CDMA in ad hoc network is to assign "codes" to different nodes and keep them updating with the change in topology. We investigate the code assignment problem on a CDMA network with a hidden terminal interference, which has been proven to be NP-hard. In this paper we propose a new clustering algorithm and a new dynamic code assignment algorithm which is adaptive to changes in the network topology.
