摘要

在无线多跳网络中，利用虚拟骨干网转发报文可以有效提高网络效率。在现有ECHO协议的基础上，提出了一种ECHO‑OPT优化方案，在关键节点决策过程中考虑节点的能量因素，并在消息转发的过程中对关键节点集中的冗余节点进行优化裁剪。在实验中研究了通信范围对冗余节点的影响并在固定网络密度与动态网络密度下测试协议的网络性能。仿真结果表明，在高密度网络中，ECHO‑OPT相对于ECHO可平均优化4.67个关键节点集大小，同时相对于多点中继（multi-point relay，MPR）与ECHO分别降低了65%与32%的网络负载，而且ECHO-OPT还拥有更高的网络生命周期。

Abstract

In wireless multi-hop networks，using the broadcast backbone to forward messages can effectively improve network efficiency.Based on the existing ECHO protocol，an optimized ECHO-OPT scheme was proposed，which considered the energy factor of nodes in the decision-making process of critical nodes，and optimized the redundant nodes in the critical node set in the process of message forwarding.In the experiments，the influence of communication range on redundant nodes was studied and the network performance of the protocol was tested under fixed network density and dynamic network density.The simulation results show that compared with ECHO，ECHO-OPT can optimize the size of critical node set by an average of 4.67 in high-density networks，and reduce the network load by 65% and 32% respectively compared with MPR and ECHO.At the same time，ECHO-OPT also has a higher network lifetime.
