| 摘 要： | 在无线Mesh网中常出现网络分割的现象,本文从优化通信可靠度的角度展开多网关节点的布设方案的研究。首先提出基于链路质量指标计算链路的状态和有效概率的方法,接着设计子网划分算法,然后提出具有时效性的可靠度计算模型。通过NS-2下的仿真实验,结果证明了基于可靠度的网关节点选择方案的有效性。

| Abstract: | Network partition often occurs in wireless Mesh network,and the layout of gateway nodes are discussed in this essay from the perspective of improving the communication reliability.The method for calculating the link state and effective probability based on link quality indicators is firstly proposed,and thensub netting algorithm is designed,following that the time-sensitive reliability model is presented finally.The results of NS-2 experiments demonstrate the effectiveness and superiority of the gateway node selection program based on the reliability. |
