分析移动自组网中节点受干扰的2个因素,网络拓扑结构和网络流量分布,并对这两方面的影响程度进行量化.基于拓扑结构干扰和网络流量干扰,提出具有干扰识别特点的路由度量.提出干扰识别的路由协议IADSR,该协议根据路径的干扰情况来选择路由,由此实现网络吞吐量及性能的提高.实验表明,在网络负载较重时,IADSR协议性能优于DSR及DIAR协议;与DSR协议相比,网络吞吐量提高7.8%,网络端到端时延下降9.4% 。
This paper analyzed how the network topology and traffic distribution generated the interference among nodes, and classified the interference into two types - topology interference and traffic interference. Based on the formulation of topology and traffic interference, an interference- aware metric was introduced to evaluate the route's ability to handle traffic, and an interference- aware routing protocol IADSR was presented. Simulation results show that when the network traffic is heavy, IADSR outperforms DSR and DIAR. Compared with DSR, IADSR can improve the average network throughput by 7.8 %, and the average end - to- end delay decreases by 9.4 %.
