| 摘 要： | 无线传感器网络中，感知节点的合理分布以及网络拓扑的动态调整对于更加有效地进行信息收集以及提高网络的生存期限都具有重要的作用。为此，针对传感器网络的初始规划提出了一种基于遗传算法的最优分布。仿真结果表明，算法能够针对特定的目标区域获得较好的节点分布。在最佳分布的基础上，结合传感器网络的拓扑管理和节点定位，引入了一种有效的传感器网络拓扑和节点分布优化方法，为传感器网络的拓扑性能管理提供了有效的算法保证。

| Abstract: | In sensor networks, a reasonable distribution of sensor nodes and dynamic topology adjustment plays an important role in information aggregation and network survival. To solve this problem, an optimal distribution based on genetic algorithm is proposed in the initial planning of sensor network. Simulation output shows that this algorithm can achieve optimal node distribution in object area. On this base, a new optimizing algorithm of sensor node distribution is designed by utilizing topology management and node localization in sensor network, which provides a sound effective means in the topology management of sensor network. |
