| 摘 要： | 无线传感器网络中基于规则网络的密钥预置方案具有预置开销小、寻径快等特点，但这类方案直接对偶密钥建立的概率较低。该文基于已经存在的节点连通集团，针对传感器网络对偶密钥连通图，提出层次连通框架，定义节点层次连通度，给出节点本地搜索算法。仿真结果表明该算法能提高节点的平均密钥连通度。 |
| 关 键 词： | 对偶密钥 无线传感器网络 密钥连通图 |

| Abstract: | Key pre-distribution schemes based on regular network such as hypercube have several advantages in Wireless Sensor Networks(WSN). Examples are lower storage cost and able to find a proper key path more quickly.However,the probabillity to establish direct keys is fairly low in hypercube-based key pre-distribution.Based on available connected components,the framework of hierarchical connectivity is presented in key-sharing graph of sensor networks.The definition of node's hierarchical degree is included,and a... |
| Keywords: | pairwise key Wireless Sensor Networks(WSN) key-sharing graph |
