摘要

提出了一种基于距离预测的扩展环路由发现方法

该方法通过提取历史记录中的长程信息和瞬时信息

通过加权修正之后

预测到目标节点的距离跳数

在此基础上

计算扩展环搜索的3个参数:起始TTL值、广播阈值和扩展步长

减少了路由发现的盲目性。仿真结果表明

与洪泛和传统扩展环搜索相比

该方法节省了路由开销

降低了分组的端到端时延

提高了网络性能。

Abstract

A scheme of route discovery was provided based on the distance prediction to destination.Hops table was established to store historical records.The long-range information and instantaneous information were extracted from historical records.The distance to the destination was calculated by weight sum of both long-range information and instantaneous information.By aid of the distance predicted

the optimized parameters of ERS including the initial TTL value

broadcast threshold and step size of ERS were calculated.Simulation results showed that the new scheme significantly improved performance of the protocol under many kinds of simulation scenarios.The routing overhead was saved and the end-to-end delay of the packet was reduced.At the same time

the new scheme was also easy to implement.
