| 摘 要： | 针对节点活动性的差异，给出了节点质量的定义，提出了基于节点质量的自适应散发和等待路由协议。该协议通过引入节点质量的观点来动态地转发报文拷贝数，从而避免了二分散发和等待路由协议在转发报文拷贝数时的盲目性。仿真结果显示，该协议更能够适应自组织状况下动态的网络拓扑，在改善报文递交率和延迟的同时能显著提高报文的递交效用、减小网络开销率。

| Abstract: | This paper presented the notion of QoN(quality of node) based on the differences of node activity. Then presented the QoN-ASW (adaptive spray and wait routing based on QoN) protocol, which introduced the notion of QoN to forward the number of message copies dynamically. This protocol could avoid the blindness of the BSW routing when message copies were forwarded. The simulation results show that the protocol of QoN-ASW is more able to adapt to the dynamic self-organizing network topology, which can significantly enhance delivery utility and reduce the overhead ratio while improving the delivery probability and reducing the delay. |
