工业无线传感器网络需要快速可靠的路由维护机制来保证网络运行的稳定性并延长网络生存周期.传统的单路径路由维护机制由于受到单路径路由方式的限制,在维护速度和维护的准确性等方面存在问题.提出一种基于双向多路径的快速路由维护机制,通过网关节点双向检测,主辅路径相互维护的方式,提升了路由维护速度,保证了路径检测的可靠性.实验结果表明双向多路径快速路由维护机制能够在少量增加网络能耗的前提下,有效地改善路由维护时间和路由维护准确率等网络性能.
Industrial wireless sensor network needs fast and reliable route maintenance mechanism to ensure the stability of network operation and prolong the network life cycle.Traditional single-path routing maintenance mechanism is limited by single-path routing method, in terms of maintenance speed and accuracy of maintenance There is a problem.This paper proposes a fast route maintenance mechanism based on two-way multi-path, which improves the route maintenance speed and ensures the reliability of path detection through the bidirectional detection of gateway nodes and the mutual maintenance of the primary and secondary paths.The experimental results show that the bidirectional multi- The fast route maintenance mechanism can effectively improve the network performance such as route maintenance time and route maintenance accuracy with a small increase of network energy consumption.
