摘　　要：为保证面向组播服务的虚拟网映射到无线mesh网导致的数据包丢失率低于一定服务质量需求,提出一个解决具有可靠性约束的虚拟网安全组播映射到有损链路的无线mesh网的轻方法.通过伺机转播和VEWL算法,在满足相应应用可靠性约束的同时减少虚拟网的激活时间,进一步提高网络资源的利用率;结合文[9]的无线mesh网密钥管理新方案,实现安全组播服务.以NS2进行仿真实验,结果表明,该方法优于纯粹的广播或单播解决方案.To ensure that the packet loss rate of multi - cast service for the virtual network embedded in the wireless mesh network is below a certain QoS service demand, we propose a light method to solve the problem how to let virtual network secure multi - cast with reliability constraints embedded lossy links WMN network. By opportunistic replay, it meets reliability constraints in the corresponding applications, meanwhile it also minimize the virtual network＇ s activation time to further improve the utilization of network resources. Combined with the new wireless mesh network key management pro- gram in references [ 9 ] , this method achieves secure muhicast services. Based on NS2 simulation re- suits show that the novel method is better than either purely broadcast or uni -cast solutions.
