基于多约束条件的Ferry路由机制的研究

Study of Ferry Routing Scheme Based on Multi-Constraint

  • 摘要: 针对偏远乡村网络的问题,结合Message Ferry机制,提出了基于多约束条件的Ferry路由机制(MCFR). 该机制充分利用Ferry中所携带的数据包信息和节点位置信息计算Ferry到各个节点的评估值,通过评估值选择Ferry的下一跳. 仿真结果表明,相对于消息摆渡路由机制(MFR),该路由机制能够提高投递率,并减小端到端时延.

     

    Abstract: On the basis of Message Ferrying approach (MFR), this paper proposes a Ferry routing scheme for remote village networks called multi-constraint Ferry routing (MCFR). The routing scheme makes full use of the packet's information carried in Ferry and the information of the node location to calculate the evaluation value from Ferry to each node. The next hop of the Ferry is designated by the maximum evaluation value. Simulation results show that the proposed MCFR scheme is better than the MFR because it has a higher delivery ratio and a lower end-to-end delay.
