Implementation and Optimization of AODV Routing Protocol Based on TinyOS for WSN

摘要:

针对无线传感器网络在矿山物联网的应用,文章提出了AODV路由协议在TinyOS操作系统下的实现框架,设计了数据帧、路由表与路由缓存机制；文章针对传统型AODV协议的丢包率与跳数之间呈级数增长的问题,分析了多跳衰减的原因,提出了一种基于RSSI的改进型无线传感器网络RSSI-AODV协议,采用RSSI作为路径选择的依据；实际测试表明:七跳链路总丢包率低至0.3%,优于传统AODV路由协议性能。

Abstract:

According to the application of Wireless Sensor Network (WSN) in Mine Internet of things (IOT), a framework of AODV routing protocol has been proposed based on TinyOS operating system. And the data frame, routing table and routing caching mechanism are designed. In traditional routing protocol AODV, the packet loss ratio gets higher with the number of hops increasing. Then a kind of improved RSSI-based routing protocol named RSSI-AODV has been proposed, after analyzing on the reasoning of multi-hops attenuation. Finally, actual test result shows that our improved protocol is more advantaged than the traditional one, as the packet loss rate is less than 0.3% in 7 hops.
