| 摘 要： | 在分析现有机会网络转发控制策略的基础上，针对采用固定效用值阈值的机会网络转发控制，提出了一种基于节点能力状况的自适应转发控制策略（adaptive forwarding algorithm based on nodal capacity condition，AFNC）。该策略根据节点的能力状况计算阈值控制因子，自适应调整不同网络传输状况以及通信机会下的数据转发条件。仿真实验表明，与现有的几种典型转发控制相比，AFNC在保证较低传输延迟和较高传输成功率的基础上，通过减少节点间的转发次数，有效地降低了网络传输开销。

| Abstract: | Based on the analysis of fixed utility threshold of the forwarding control for Opportunistic networks, a data forwarding scheme named adaptive forwarding algorithm based on nodal capacity condition(AFNC) was proposed. In this scheme, every node calculated the utility threshold control factor according to the nodal capacity condition, and adaptively controlled the data forwarding condition in different network status and different communication opportunities. The simulation results show that, in ensuring lower transmission delay and higher transmission success rate, AFNC reduced the network load and the energy consumption in the process of data transmission. |
