针对节点随机部署的静态无线传感器网络覆盖率低、能耗高和时延长等问题,提出基于三角剖分的无线传感器网络元胞感知覆盖算法.该算法通过改进的Delaunay三角剖分实现网络区域的唯一性划分;采用元胞思想确认节点间邻域关系,并通过设置节点感知半径完成网络拓扑控制;将节点剩余能量、时间延迟和历史转发概率作为机器学习感知器的输入数据进行训练,进而找到最优的数据转发通信路径.仿真结果表明,本文提出的算法将网络覆盖与数据传输相结合,相较于其他算法,覆盖率提高13%~34%,节点能量消耗减少了2.25~2.50 J,网络生命周期延长了25%,网络时延下降了0.25~1.18 s. |

Aiming at the problems of low coverage,high energy consumption and long delay of static Wireless Sensor Networks(WSNs) that are deployed randomly,a cellular perceptron coverage algorithm for WSNs based on triangulation is proposed.The algorithm applies improved Delaunay triangulation to achieve unique division of the network area.Then,it uses the cellular idea to confirm the neighborhood relationship between nodes and realizes network topology control by setting the node perception radius.Finally,the remaining energy of the node,the time delay and the historical forwarding probability are trained as the input data of the machine learning perceptron to find the optimal data forwarding communication path.The algorithm combines network coverage with data transmission.Compared with other algorithms,the coverage is increased by 13%~34%,the node energy consumption is reduced by 2.25~2.5 J,the network life cycle is prolonged by 25%,and the network delay is reduced by 0.25~1.18 s. |
