| 摘 要： | 摘要： 由于基于距离的位置辅助路由算法无法抵御恶意节点拒绝服务攻击(denial of service, DoS)的安全漏洞，引入信任度量，将信任模型加载到路由发现中以解决恶意节点对路由的DoS攻击. 改进的基于信任的安全位置辅助路由利用节点的直接信任度和推荐信任度来避免信任值低的恶意节点加入路由转发工作. 仿真结果表明，ST-LAR(secure trust location-aided routing)能更有效地抵御恶意节点的DoS攻击，并在平均端到端时延、分组成功投递率、吞吐量等方面优于DBLAR.

| Abstract: | To deal with the safety weakness in resisting active attacks from malicious nodes, trust metric is introduced to combat the attacks by loading a trust model on the proposed distance-based location-aided routing (DBLAR). The improved routing algorithm ST-LAR uses direct trust and recommendation trust to prevent malicious nodes with low trust value from joining the forwarding. Simulation results show that STLAR
can effectively resist attacks from malicious nodes. Its performance is also better than DBLAR in terms of average end-to-end delay, packet successful delivery ratio and throughput. |
