基于OMNet++的主从式异构物联网仿真平台的研究

摘要

本文分析并研究了融合GPRS和WLAN网络协议的主从式异构网络的物联网的系统性能，通过在OMNet++框架内进行建模，搭建仿真平台。在这种网络模型中，传感器网络的主节点同时作为局域网网关工作。通过仿真实际异构物联网场景的性能测试，研究网络延时、正确送达率与节点数量、报文长度等的关系，以实现在大规模搭建传感器网络前根据具体的网络性能和通信质量要求进行整体部署。%In this paper, the network performance of a master-slave heterogeneous network with GPRS and WLAN protocols isa-nalyzed and studied, by building an Internet of Things (IoT) simulation platform with OMNeT++, in which the master nodes also work as a LAN gateway. The relationship between network delay, rate of delivery and number of nodes, packet length is studied through simulation based on heterogeneousscenarios, in order to make a global arrangement according to the requirements of net-work performance before building a sensor network.
