| 在无线传感器网络中,信息的传输需要安全的保护.在分簇管理的基础上,GTMS(group-based trust management scheme)算法利用节点的可信度来实现路由的安全.但是,它的可信度表示方法过于简单,无法反映信誉复杂性.因此,在基于区间的云相似度比较算法的基础上,以云理论为基础构建节点可信度,提出了基于云信任模型和蚁群算法的无线传感器网络簇可信路由算法.研究结果表明,在准确判定簇内节点可信度的基础上,CRPCTMAS (cluster reliability protocol based on cloud trust model and the ant scheme)算法建立了安全、有效的路由,保证了路由的高有效发包率,延长了网络的生命周期 |

| Abstract: |
| In WSN (wireless sensor network), the security of message transmission is needed. GTMS (group-based trust management scheme) guarantees the security of routing by node trust. However, its description of trust is too simple to represent the complexity of the entity. Hence, based on the comparison method of cloud similarity, this paper establishes a node trust, and proposes a new routing protocol CRPCTMAS (cluster reliability protocol based on cloud trust model and the ant scheme). The performance analysis show that, based the correct judgment of node trust, CRPCTMAS can find a security route not only to guarantee the high ratio of data packet emission but also to prolong the lifetime of the network. |
