提出了一种用于无线自适应移动信息系统的多集群、多跳分组无线网络体系结构。所提出的网络支持多媒体流量并依赖于时分和码分接入方案。该无线电网络不像传统蜂窝系统那样受到有线基础设施的支持。因此，它可以立即部署在根本没有基础设施的地区。通过使用分布式集群算法，节点被组织成集群。簇头充当本地协调器来解决信道调度、执行功率测量/控制、维持时分帧同步以及增强时隙和代码的空间重用。此外，为了保证实时流量的带宽，该架构支持虚拟电路并在呼叫建立时为电路分配带宽。该网络可扩展至大量节点，并且可以处理移动性。仿真实验评估了所提出的方案在静态和移动环境中的性能。
A multi-cluster, multi-hop packet radio network architecture for wireless adaptive mobile information systems is presented. The proposed network supports multimedia traffic and relies on both time division and code division access schemes. This radio network is not supported by a wired infrastructure as conventional cellular systems are. Thus, it can be instantly deployed in areas with no infrastructure at all. By using a distributed clustering algorithm, nodes are organized into clusters. The clusterheads act as local coordinators to resolve channel scheduling, perform power measurement/control, maintain time division frame synchronization, and enhance the spatial reuse of time slots and codes. Moreover, to guarantee bandwidth for real time traffic, the architecture supports virtual circuits and allocates bandwidth to circuits at call setup time. The network is scalable to large numbers of nodes, and can handle mobility. Simulation experiments evaluate the performance of the proposed scheme in static and mobile environments.
