摘要

在移动自组织网络(MANET)环境中，传输功率控制(TPC)通过增加信道的空间重用来减少数据包传输中消耗的总能量和/或提高网络吞吐量。本文提出了一种基于预测滤波器(卡尔曼滤波或扩展卡尔曼滤波)的分布式相关功率控制方案。预测滤波器用于估计即将到来的干扰。在MANET环境中，发送端和接收端都利用预测的干扰为各自关联的后续数据包分配相关的功率值，以保证IEEE 802.11四路握手通信(RTS/CTS/DATA/ACK)的成功进行。不同拓扑结构的仿真结果表明，所提出的功率控制方案可以获得显著的吞吐量和能量增益。

A Distributed Correlative Power Control Scheme for Mobile Ad hoc Networks using Prediction Filters

Transmission power control (TPC) in a Mobile Ad hoc network (MANET) environment reduces the total energy consumed in packet delivery and/or enhances network throughput by increasing the channel's spatial reuse. In this paper, a distributed correlative power control scheme using prediction filters (Kalman or extended Kalman) is proposed. The prediction filter is used to estimate the forthcoming interference. Both the transmitter and receiver in MANET environment make use of predicted interference to assign correlative power values to their associated ensued packets to guarantee the success of the IEEE 802.11 four-way handshaking communication (RTS/CTS/DATA/ACK). Simulation results for different topologies are used to demonstrate the significant throughput and energy gains that can be obtained by the proposed power control scheme.
