【摘要】：现有移动互联网的体系结构在网络的通信上有许多规定和限制,尤其要求保证网络的连通性,这使得在某些突发状况、通信基础设施不足的移动通信场景下的应用受到了限制.提出一种机会式内容共享机制,该机制利用网络中参与节点相遇的机会进行内容转发,转发过程对网络的连通性要求较低,对网络基础设施依赖较小.在本文内容共享机制下,采用集中式、分布式结合的网络结构,在网络中加入一定数量的静态节点对网络进行管理,在机会转发算法上,利用静态节点位置相对固定的特点,提出了基于位置的机会转发机制LAOF和基于传染算法的转发机制ERF,仿真实验显示了较好的转发性能.
[Abstract]:The current architecture of mobile Internet has many regulations and limitations on network communication, especially to ensure network connectivity, which limits the application of mobile communication scenarios where communication infrastructure is inadequate in some burst situations. An opportunistic content sharing mechanism is proposed in this paper. The mechanism takes advantage of the encounter of the participating nodes in the network to forward the content. The forwarding process requires less network connectivity and relies less on the network infrastructure. Under the mechanism of content sharing in this paper, a centralized and distributed network structure is adopted, and a certain number of static nodes are added to the network to manage the network. In the opportunistic forwarding algorithm, the static node position is relatively fixed. A position-based opportunity forwarding mechanism (LAOF) and an infectious algorithm-based forwarding mechanism (ERF) are proposed. The simulation results show good forwarding performance.
