Topology Control and Security Maintenance Based on Complex Network in Wireless Sensor Networks

摘要:

通过理论推导,得到复杂网络参数与无线传感器网络(WSN)网络容量的关系式.在关系式指导下,运用删减冗余边、添加长程边等方法,对WSN拓扑控制以提高网络容量.针对经过拓扑控制后具有小世界特性的WSN,提出一种考虑节点病毒传播强度的病毒传播局域控制方法.研究表明,拓扑控制可以有效提高WSN网络容量,通过对少量的重要节点免疫,可以节省免疫成本,提高WSN抗病毒攻击能力.

Abstract:

A relationship between complex network parameters and wireless sensor networks(WSN) capacity is obtained through theoretical derivation.Under the guidance of the relationship,a topology control is employed in removing some superfluous links and adding some shortcut,to increase the network capacity.According to the small-world effect which the WSN possesses after the topology control,a local area control of virus spreading is proposed in the light of the virus spreading intensity of nodes.The research suggests that by topology control,the WSN network capacity is effectively improved; by immunizing a small amount of essential nodes,the immune cost is saved,and the ability of anti-virus attack is enhanced.
