无线传感器网络的实际应用很大程度上依赖于可靠性,如何对其抗毁性进行评价是目前研究的热点.对此,基于元胞蚁群算法提出一种新的度量方法(Invulnerability based on Cellular Ant,ICA).该方法首先利用节点重要度建立了网络抗毁性的评价指标和节点最大流量模型,同时通过元胞蚁群算法进行求解.其次,以实际数据进行仿真实验,结果发现网络抗毁性与节点数之间成正相关,而与能量消耗比之间成负相关.并且相比于二维抗毁性算法,ICA算法表现出较好的适应性.
The practical application of wireless sensor networks relies heavily on reliability, and how to evaluate its survivability is a hot topic nowadays.Therefore, a new measurement method based on cellular ant colony algorithm (Invulnerability based on Cellular Ant, ICA) .In this method, firstly, the evaluation index of network invulnerability and the maximum traffic model of nodes are established by using the importance of nodes, and the solution is solved by cellular ant colony algorithm.Secondly, based on the actual data, the simulation results show that network resilience Destructiveness is positively correlated with the number of nodes, and negatively correlated with the energy consumption ratio, and the ICA algorithm shows a better adaptability than the two-dimensional invulnerability algorithm.
