传送功率控制是无线自组网中资源管理和控制干扰的中心技术.传统上功率控制只是用作消除信道消隐负作用的一种手段,当前观点一般认为功率控制是一种可以为单个用户提供服务质量的灵活机制.提出一种分簇算法以达到减轻网络拓扑的动态变化的同时节省电能.此提案是基于全球定位系统的(GPS).根据移动主机的历史轨迹预测它下一个最可能处在的位置,预先调整传送功率.为了最大化网络的吞吐量,算法自适应性的控制每个簇在合适的大小.在GlomoSim模拟器上仿真了提出的算法.仿真结果表明,它是无线自组网中有效的拓扑管理机制,对由高速运动主机组成的网络特别有效.
Transmission power control is the central technology of resource management and control interference in MANET.Traditionally, power control is only used as a means to eliminate the negative effect of channel shedding. Current view is generally considered that power control is a method that can provide for a single user A flexible mechanism of service quality A clustering algorithm is proposed to save power while reducing the dynamic changes of the network topology.This proposal is based on Global Positioning System (GPS) and predicts the next most likely location based on the mobile host’s historical trajectory In order to maximize the throughput of the network, the algorithm adaptively controls the size of each cluster at a suitable size.The proposed algorithm is simulated on the GlomoSim simulator.The simulation results show that it is a wireless The effective topology management mechanism in networking is particularly effective for networks composed of high-speed motion hosts.
