Abstract: There are many modern network applications that require QoS provisions in Ad hoc network.An energy efficient QoS topology control algorithm is proposed.It adjusts transmission power of nodes to construct new topology which can meet bandwidth and delay requirements for services and the total transmission power of nodes is minimized.Simulation results show that the algorithm has a better performance and will provide an effective solution for realizing multimedia applications in mobile network.

摘要: 越来越多的新应用要求在Ad hoc网络中能够提供QoS保证,对此提出了一种能效的QoS拓扑控制算法。该算法通过调整节点发射功率来构造新的网络拓扑以满足业务流对带宽和时延的要求,同时使得节点总的能耗最小。仿真结果显示该算法具有较好的性能,可以为移动网络中实现多媒体应用提供一种有效途径。
