摘 要: 在面对快速数据流时,网络流量的激增和链路的不稳定性必将给带宽受限的无线传感器网络(wireless sensor network,WSN)带来严重的网络拥塞与丢包现象。因此,这里在单路径低功耗有损网络路由协议(routing protocol for low-power and lossy networks,PRL)的基础上,提出缠绕多路径的改进策略,并在多路径的基础上对网络流量进行按路径权重的负载均衡优化。最后通过COOJA仿真工具对其进行仿真分析,测试结果表明:优化后的RPL在面向快速数据流和有损链路时可以有效缓解网络拥塞和降低丢包率。
关 键 词: 无线传感器网络;低功耗有损网络路由协议;多路径路由;负载均衡;COOJA

Abstract: In the face of rapid data traffic, network traffic surges and unstable link would bring grievous network congestion and packet lost to the limited bandwidth of wireless sensor network. So, in this paper, on the basis of single path routing protocol for low-power and lossy networks(PRL), we proposed the improvement strategy of winding multipath. Furthermore, according to the multipath, we did the load balancing optimization based on the load weight. In the end, we provided simulation analysis through COOJA simulation tool, the results showed that the optimized RPL can effectively alleviate the network congestion and reduce the packet loss in the face of rapid data traffic and lossy link.
Key words: wireless sensor network; routing protocol for low-power and lossy networks; multipath routing; load balancing; COOJA
