强拓扑关系下嵌入式激光传感网络设计

Design of embedded laser sensor network based on strong topology

传统方法在对嵌入式激光传感网络设计中,由于没有考虑强拓扑关系对网络的约束作用,网络节点运算速率缓慢且网络节点规划效果差,导致设计得到的激光传感网络稳定性差。因此,提出强拓扑关系下嵌入式激光传感网络设计方法,将激光传感网络设计问题转化为网络规划节点定位问题,其通过引入拓扑关系模型来构建强拓扑关系下的网络节点规划模型,采用该模型对某个网络情景的发生情况进行预设,采取对已知网络路段进行扩张改进的办法,确保网络在均衡状态以及强拓扑关系下,得到符合强拓扑关系的网络节点规划方案。通过该方案对网络规划节点进行定位,构建非线性方程以线性化的求解形式,获取目标网络节点的坐标,对规划节点进行准确定位,实现了强拓扑关系下嵌入式激光传感网络设计。实验结果表明,所提方法可显著提升网络节点的规划效率,提升网络节点的规划效果,设计得到的激光传感网络稳定性较好。

In the design of embedded laser sensor network, the traditional method does not take into account the constraint of strong topology relationship, so the network node operation rate is slow and the network node planning effect is poor. The stability of the designed laser sensor network is poor. Therefore, an embedded laser sensor network design method based on strong topology is proposed, which transforms the design of laser sensor network into the node location problem of network planning. The network node planning model under strong topological relationship is con? structed by introducing the topological relation model. The model is used to presuppose the occurrence of a network scenario, and to extend and improve the known network section to ensure that the network node planning model is based on the topology relation model. In the condition of equilibrium and strong topological relation, the network node planning scheme is obtained which accords with the strong topological relation. Through this scheme, the nodes of the network planning are located , and the nonlinear equations are constructed in the form of linearization, and the coordi? nates of the nodes of the target network are obtained , and the planning nodes are located accurately. The design of em bedded laser sensor network based on strong topology is realized. The experimental results show that the proposed method can significantly improve the planning efficiency of network nodes and improve the planning effect of network nodes, and the stability of the laser sensor networks designed is good.
