摘要
对于无线网络技术,在满足一定的服务质量要求前提下,如何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。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实现QoS参数和能量优化方面具有明显的优势。
The technology of wireless network must be solved that meet a certain quality of service in order to optimize energy of whole networks. The existing topology control algorithms focused on how to improve network performance rather than reduce energy consumption. A service triggered based crossqayer topology control algorithm （STC） is proposed. 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 requirement of optimizing QoS parameters and energy.
