自适应的机会网络消息副本调整策略

提出了一种具有自适应的消息副本调整策略.该方法对消息副本的数量属性分层划分,通过控制属性来控制副本数量,是一种可定量定性调整的策略.根据划分的属性提取副本数优先度,综合考虑消息的其他属性,完成基于效用优先级消息队列的调整.实验结果表明,该方法能够自适应调整消息副本的冗余程度,达到较高的投递率,对不同网络负载有较高的适应性.

The Optimization Strategy for Adaptable Opportunistic Network Message Replica

This paper presents an adaptive message replica adjustment strategy.This method is a kind of quantitative and qualitative adjustment strategy to control the number of replicas by controlling attributes,and then according to the attribute partition,the priority of the replica is extracted.Moreover,the other attributes of the message are considered to form the message queue optimization based on the priority of utility.The experimental results show that the proposed method can adaptively adjust the redundancy degree of message replicas to achieve higher delivery rate,and have higher adaptability to different network loads.
