网络节点均衡性优化控制模型仿真研究

After the Network Intrusion Control Node Equilibrium Model Simulation

对网络节点均衡性进行准确合理的控制,可保障网络在入侵后还能保持良好的运行状态。在进行网络节点均衡性控制过程中,需要精确计算控制网络间的通信消耗和剩余节点能量,建立网络节点均衡性控制模型。而传统方法只能对剩余节点能量和通信消耗进行粗略的估计,存在建模误差大的问题。为此建立了一种新的网络节点均衡性优化控制模型,以保持耗能最小路径为控制目的,利用局部最小生成树理论控制网络结构,将选择链路节点的权值视为新的加权函数,并建立网络模型,在组建网络拓扑模型时考虑了节点间的通信消耗和节点剩余能量,依据节点能量的变化对网络拓扑结构进行动态调节,利用通信损耗链路作为衡量标准,同时考虑中继节点的剩余能量情况,避免了网络入侵后部分节点能量过早耗尽。仿真结果表明,所提模型能够有效地延长网络入侵后节点的生命周期,实现节点能量的均衡性控制。

This research builds a new optimization control model for equilibrium of network node. Aiming at maintaining path with minimum energy consumption, we used local minimum spanning tree to control network structure, then used weight of chosen link node as new weighting function and built network model. The research also considered communication consumption among nodes and residual energy of node during building network topology model and adjusted topology structure dynamically according to variation of node energy. The research used link of commu- nication consumption as measuring criterion and considered residual energy case in the meantime to avoid untimely exhaustion of partial node after network intrusion. Simulation results show that the model can prolong life cycle of node after network intrusion and achieve the equilibrium control of node energy.
