摘要:

针对间断连接无线网络中限制消息副本路由机制的低消息投递率与存在恶意节点攻击的问题,提出了一种节点状态实时感知的安全路由机制,采用供给需求模型对节点转发消息的过程进行建模,通过动态感知节点活跃度、邻居节点剩余缓存率和相遇节点声誉值,结合消息生存时间比,建立节点对消息配额的供给需求模型,进而合理分配稀缺的配额资源,并在本地网络状况满足约束条件下,依据消息需求弹性动态更新消息配额,实现可靠的安全路由机制。数值结果表明,所提出的路由机制有效地减小了恶意节点攻击行为的影响,并大幅改善消息投递率和消息平均时延。

Abstract:

Because of low message delivery probability and nodes malicious attack behaviors in the quota-limit routing for intermittently connected wireless networks,a secure routing is proposed based on supply and demand relationship perception.According to activity degree,average residual buffer ratio of neighbors and encountered nodes reputation dynamically perceived by nodes,the encountered nodes in real time build the supply and demand model and determine the message quota allocation combined with the message survival ratio in common.When network status meets constraint situations,update message quota dynamically based on demand elasticity of message.Simulation results show that the proposed strategy effectively reduces influence of nodes malicious behaviors and improve network performance greatly.

Key words: intermittently connected wireless networks, supply and demand model, message quota, secure routing
