【摘要】 应用于工业的无线网络有着强实时性和高可靠性的要求,路由协议是WIA-PA网络的关键技术。基于DSDV的多路径路由协议,它采用了基于链路稳定性的路由选择标准和节点不相交路径策略,选择一条最高稳定性的路由传输数据,确定次稳定性、不相交路径作为备份路由。与DSDV相比,多路径算法在网络的稳定性和数据传输的性能上有了显著的提高。更多还原

【Abstract】 WIA-PA is a new industrial wireless network for process automation.The industrial wireless networks are required to show hard real-time property and high reliability,and routing protocol is the key technology of WIA-PA.Based on DSDV,the multi-path routing protocol uses routing criteria based on link stability and the node disjoint path strategy to choose a routing with maximum stability to transmit data.Then the backup routing is determined by the stability and the disjoint path.Compared with DSDV,the multi-path algorithm offers significant improvements on network stability and performance of data transmission.更多还原
