攻击性网络充分利用节点间的机会相遇来传输分组。针对机会网络中节点能量有限和链路变化频繁的特点，提出了一种综合考虑节点能量消耗、中继节点到达目的节点的概率、数据包生存时间和数据包副本数量的路由度量.在此基础上，提出了一种可控的多副本路由方法，该方法采用单分支扩散策略来实现对数据包副本数量的动态控制.仿真结果表明，该方法可以避免单个节点的负载过大，保证节点间的能量公平性，延长网络生存时间，有效提高数据包的投递率。© 2017日本电气工程师协会。由John Wiley & Sons公司出版
Opportunistic networks take full advantage of opportunistic encounters among nodes to transfer packets. According to the characteristics of the limited energy of nodes and the frequent link variation in opportunistic networks, we introduce a novel routing metric that comprehensively takes into consideration the energy consumption of nodes, the probability of relay nodes meeting their destination, the time‐to‐live of the packet, and the approximate number of packet copies. Based on this metric, we propose a controllable multi‐replica routing approach in which a single‐branch diffusion strategy is applied to achieve the goal of dynamically controlling the number of replicas of packets. Our simulation results show that the proposed approach can avoid excessive load on individual nodes, guarantee the energy fairness among nodes, prolong the network lifetime, and effectively improve the delivery ratio of packets. © 2017 Institute of Electrical Engineers of Japan.
