摘　　要：针对在节点移动性较低但非静止的条件下,机会网络的传统摆渡路由策略并不适用的问题,提出了一种适应于动态网络环境下的实时确定信使移动路线的摆渡路由协议。信使通过识别网络中的节点,动态确定移动路线,实现节点访问与数据传递。利用多个信使的协同工作,克服单一信使的性能瓶颈,保证数据的传输成功率。通过延时分析和仿真实验,验证了增加信使数目可以降低路由协议的延时。同时利用仿真实验说明了提出摆渡路由的可行性与合理性。In consideration of the problem that traditional ferry routing protocols for opportumistic networks do not suit the condition that nodes have the low mobility but are non-static,this paper proposes a new ferry routing protocol which suits dynamic network environments.and can make real-time determination of messengers＇ ferry routing.By identifying the nodes in the network,the protocol can dynamically determine the moving path of ferries,and then access nodes and transfer data.By using multiple cooperatively worked ferries,the protocol can overcome the performance bottleneck of single ferry,and also ensure the data delivery rate.The delay analysis and simulation results show that increasing the number of ferries can reduce the routing delay.The simulation results also verify the feasibility and rationality of the proposed routing protocol.
