摘要

摘要: 針對(duì)節(jié)點(diǎn)感知半徑不均衡的移動(dòng)傳感網(wǎng)絡(luò)節(jié)點(diǎn)的部署問(wèn)題，論文提出一種基于VL(Voronoi Laguerre)圖分割的節(jié)點(diǎn)自主部署算法(Autonomous Deployment Algorithm, ADA)。ADA先對(duì)目標(biāo)區(qū)域做VL圖劃分，將目標(biāo)區(qū)域的覆蓋任務(wù)在各個(gè)傳感器節(jié)點(diǎn)之間進(jìn)行分配。分配到覆蓋子區(qū)間任務(wù)的節(jié)點(diǎn)通過(guò)構(gòu)造VL受控多邊形來(lái)確定下一輪候選目標(biāo)位置。未分配到覆蓋子區(qū)間的節(jié)點(diǎn)則根據(jù)自身與鄰居節(jié)點(diǎn)感知圓及目標(biāo)區(qū)域邊界的幾何位置關(guān)系計(jì)算所受虛擬力，最終確定下一輪目標(biāo)點(diǎn)坐標(biāo)。網(wǎng)絡(luò)各個(gè)節(jié)點(diǎn)通過(guò)逐輪更新自身位置，從而提高網(wǎng)絡(luò)覆蓋。仿真結(jié)果表明，ADA算法在網(wǎng)絡(luò)覆蓋率、節(jié)點(diǎn)部署速度和節(jié)點(diǎn)分布均勻性等方面具有明顯的優(yōu)勢(shì)。

Abstract: To solve the deployment problem of nodes with unbalanced sensing radiuses in mobile sensor network, an Autonomous Deployment Algorithm (ADA) based on the VL (Voronoi Laguerre) graph is proposed. First, the VL graph is used to divide the target area, the coverage tasks of target area are allocated among different sensor nodes. Then, the node assigned with coverage subinterval confirms its candidate target location in next round by structuring the VL controlled polygon. The node without sub-range calculates its virtual repulsion according to the geometrical position relationship with its neighbor nodes perception circles and the target areas borders to ultimately ascertain the target point moving to. Each node in the network updates its position by rounds to improve the network coverage. The simulation results show ADA algorithm has obvious advantages in network coverage rate, deployment speed, nodes distribution uniformity and so on.
