矿井巷道WSNs等腰三角形节点覆盖模型

Isosceles triangle node coverage model of WSNs in mine tunnel

根据矿井巷道空间为线性空间,而已有的正多边形节点覆盖模型会受到巷道宽度的限制,导致节点部署冗余度过高和成本昂贵的缺点,提出了矿井巷道无线传感器网络(WSNs)等腰三角形节点覆盖模型。在一次、二次以及三次覆盖下,得到了相邻节点之间距离与覆盖度的关系。实验表明:正方形与正六边形覆盖模型的节点冗余度分别为77.78%,89.7%,而等腰三角形三次覆盖模型则为40.03%。等腰三角形节点覆盖模型降低了节点的覆盖冗余,且更加适用于矿井巷道。

Aiming at shortcomings of space of mine tunnel is linear space, and the existing regular polygon node coverage model will be affected by tunnel width restrictions, which lead to high redundancy of node deployment and expensive cost, present an isosceles triangle node coverage model of wireless sensor networks （WSNs）in mine tunnel. Under one time, two times and three times of coverage, obtain relationship between distance of adjacent nodes and coverage. Experimental results show that node redundancy of square and hexagon coverage model is 77.78 % ,89.7 % respectively, and isosceles triangle three times coverage model is 40.03 %. Isosceles triangle node coverage model decreases coverage redundancy and is more suitable for mine tunnel.
