无线传感器网络中移动场景下的安全路由重构

Security Route Reconstruction for Mobility Scenarios in Wireless Sensor Networks

为解决无线传感器网络中移动场景下的安全路由问题,尤其是网络拓扑变化后的安全路由重构问题,提出了一个安全、快速、及时而且能量有效的路由算法,能为新节点或移动节点提供及时有效的数据转发路径,通过Sink节点的移动帮助网络快速重构路由以适应网络拓扑的变化.与其他的安全路由协议需要重头开始路由构建过程相比,该安全路由重构算法在通信负载和建立路由的时间方面都要远远小于它们.

To solve the route security issue in mobility scenarios and especially the route reconstruction security issue after the network topology changes in wireless sensor networks, an immediate, fast, secure and energy-efficient route algorithm were proposed, which could provide new nodes or mobile nodes with the immediate and efficient data transfer paths and could help sensor nodes adapt the network topology changes by moving the sink node and reconstructing the route. Compared with other secure route protocols that need to reconstruct the route from the beginning, this algorithm is better in terms of communication overhead and route reconstructing time.
