| 高效、安全的路由机制是保证无线网状网络(WMN)正常工作的一个重要因素。对WMN中的多径路由(MPR)算法进行了研究。由于MPR算法存在路由分离性约束,提出了一种基于转移概率的随机路由(SR)算法,并对这两种算法进行了仿真。仿真结果表明:在节点转发次数的标准方差和最高截获率两个性能指标方面,SR算法均优于MPR算法,这说明与MPR算法相比,所提算法进一步增强了WMN网络的路由安全性。 |

| Abstract: |
| An efficient and secure routing protocol is one of the most important factors to ensure the wireless mesh network(WMN) to run successfully.In this paper,the multi-path routing(MPR) algorithm is studied.Due to the restriction of route separation,the stochastic routing(SR) algorithm based on the transition probability is proposed and both MPR and SR are simulated under the circumstances of WMN.Simulation results show that SR outperforms MRP at the performance of standard deviation and highest interception ratio.Therefore,it means that SR algorithm enhances the routing security compared with MPR algorithm. |
