| 摘 要： | 针对战术移动自组(AdHoc)网络提出一种分布式位置辅助的功率控制算法(LAPCA),它通过位置预测来推算节点的邻节点数目,进而调整信号发射功率,以保持最佳的网络连通性,由此提高整个网络的有效流量。该算法作为一个独立模块可以方便地与已有的移动自组网络路由协议相结合。采用较为适合战术环境的参考点群组移动(RPGM)模型来产生网络仿真场景,从仿真实验结果来看,几乎在所有的RPGM场景下采用该算法后的网络有效流量相对于纯粹的AODV路由协议都得到了提高。

| Abstract: | To improve the throughput of the tactical Ad Hoc networks, a distributed Location Aided Power Control Algorithm (LAPCA) is developed which computes the number of the neighboring nodes by location prediction, then adjusts transmitting power of the node to maintain an optimal connectivity when nodes are in motion. This algorithm can work as an independent module in company with most of the popular routing protocols. The Reference Point Group Mobility (RPGM) model, which is more suitable for tactical scenarios, is used to generate network simulation scenarios. As shown by the results of simulation, the throughput of the network in almost all the RPGM scenarios can be thus greatly improved with respect to the pure AODV routing protocol. |
