摘要
针对现有可信网络框架和可信度量模型不能很好的适用于Ad Hoc网络这一情况,在基于信息论的可信度量模型基础上,提出了一种面向Ad Hoc网络的多路径可信度量模型。该信任度量模型在考虑节点信任程度的同时,能够有效将业务分组在网络中均衡,避免中继节点大量承担转发任务。仿真结果表明,该模型在多跳Ad Hoc网络中能够根据信任度量值选择最优路径,避免中继转发节点缓存队列溢出丢包,能够提高网络吞吐率。
The current framework of TNC and trust evaluation model could not satisfy the performance requirements when the trusted access was needed in Ad Hoc networks. For this aim, a trust evaluation model DPET was proposed for Ad Hoc networks. Compared with the existing trust evaluation model, the DPET model could take load balancing into consideration while calculating the trust degree. Thus, it could prevent a relay node from forwarding too many packets, which could degrade the network performance. The simulation results validated that the DPET model could select the optimal path based on the trust degree value, and improve network throughput in multi-hop Ad Hoc networks.
