基于无线网络的森林防火系统的研究与改进

摘要

To the drawbacks of forest fire prevention system for wireless sensor technology,this paper presents an improved system design.The improved scheme give two Ad-Hoc mode network,and increases the reliable central network node,the wireless communication network using the improved AODV as a multi-hop routing protocol.The center node data processing using the Kalman filter pretreatment,and the data is sent random delay sending ALOHA mechanism.After many repetitive system experiments,final verification and summed up in the set can be effectively applied to actual engineering systems deployment scenarios.%论文针对现行的无线传感器技术方式的森林防火系统中的弊端,提出了一种改进的系统设计方案.改进后的方案主要采用二级Ad-Hoc模式的网络,对传统的无线传感器进行有效的改造的同时,也增加了稳定可靠的中心网络节点,无线通信网络采用改进后的AODV作为多跳路由协议,中心节点的数据处理采用卡尔曼滤波预处理,数据发送采用ALOHA机制进行随机延迟发送.系统经过反复实验,最终验证并总结出一套可以有效应用于实际工程中的系统部署方案.
