| 英文摘要 | The WSN node deployment problem is the key point of current wireless sensor network application research. For the traditional network node deployment, the convergence speed is slow, the global optimization performance is not strong, and the perception angle is limited, this paper proposed a virtual force-oriented omnidirectional perceptual coverage algorithm(VFOPCA). Based on the traditional virtual force algorithm, the algorithm proposed the force model between hotspot region and node, and adopted the 0/1 disc cover model to further optimize the network node deployment. The experimental simulation shows that the virtual force-oriented omnidirectional perceptual coverage algorithm can quickly and effectively realize the global optimization of network nodes. Compared with omnidirectional perceptual model algorithms such as VFA and DACQPSO, the algorithm has better coverage, faster convergence and lower energy consumption. |
