摘要
无线网络技术的发展对网络服务质量提出了要求，如何在满足一定的服务质量要求前提下实现能量优化是无线网络设计必须面对的问题。现有的拓扑控制算法主要集中在如何提高网络的性能，较少考虑如何优化能量消耗。本文基于跨层的思想，提出了一种业务触发式的拓扑控制算法（STC），通过在网络中建立恰好承载当前业务的拓扑结构，使得信息包可以沿着能耗优化的路径向目的节点发送。通过仿真研究表明，该算法生成的网络拓扑结构在在同时实现QoS参数和能量优化方面具有明显的优势。
The development of wireless network technology requests higher quality of network service, it is must be solved that meet a certain quality of service in order to optimizing energy of whole networks. The existing topology control algorithms focused on how to improve network performance rather than reduce energy consumption. This paper propose a cross -layer topology control algorithm （STC）based on service triggering. This algorithm is to find a new topology that just carry the current service and can send packet to destination node following the optimal path. Simulation results show that this algorithm can get a topology which can meet the QoS requirement, optimize the transmitting power and balance of energy consumption.
