摘　　要：随着无线网络技术的不断发展,无线Ad hoc网络中,快速变化的网络拓扑影响着网络的性能。因此,在实现网络能量优化的前提下,如何提供有效的QoS服务来满足多业务要求是无线Ad hoc网络所必须面对的问题。针对此问题,提出了一种基于多业务需求的拓扑控制的方法,该方法考虑业务QoS指标的同时引入跨层的设计思想,实现了跨层的功率控制,减少了网络中节点的能量消耗,延长了网络的生命周期。With the development of wireless network technology, rapidly changing network topology affects network performance in wireless Ad hoc networks. Therefore, the prerequisite for network en- ergy optimization, how to provide effective services to meet the QoS requirements of multi - service is the problem what wireless Ad hoc networks have to face. To solve this problem, a topology based on the needs of multi - service control method, while considering the introduction of service QoS indica- tors of cross - layer design to achieve a cross - layer power control, reducing the energy consumption of nodes in the network, prolong the network life cycle.
