在机会网络中，节点对之间的成功消息传输取决于消息大小、传输速度和连接持续时间。提出了一种新的报文转发算法，以提高报文投递率，降低能耗。节点之间的先前相遇特征被用来使用三点估计方法来估计未来的连接持续时间。此外，节点的缓冲区利用率被用作根据缓冲区中存储的消息的跳数来确定到达目的地的可能性的权重。仿真结果表明，与其他四种流行的路由协议相比，该转发算法具有更高的投递率和更低的开销比。此外，在所有比较的协议中，该算法获得了更好的平均剩余能量性能。
In opportunistic networks, a successful message transmission between node pairs depends on the message size, the transmission speed and the connection duration time. This paper proposes a new message forwarding algorithm to improve the message delivery ratio and reduce the energy consumption. Previous encounter characteristics between nodes are used to estimate future connection duration time using a three point estimation method. Furthermore, the buffer utilization of nodes is used as a weight for the likelihoods to meet destinations according to the hop count of messages stored in the buffer. The simulation results show that the proposed forwarding algorithm achieves higher delivery ratio and less overhead ratio than the other four popular routing protocols. In addition, the proposed algorithm gains a better average residual energy performance among all the compared protocols.
