Abstract本发明涉及无线网络资源分配技术,具体是一种面向多个线型拓扑工业无线网络共存的资源分配方法。本发明考虑多个基于TDMA的线性拓扑工业无线网络共存问题,包括调度时延下界分析、网间资源分配算法和网内资源分配算法三个部分。该方法在分析时延下界和设计资源分配算法时以整体调度时延和资源利用率作为衡量指标,在每个时隙选取最佳节点组合尽可能多的占用信道资源,提高资源利用率、降低整体调度时延。
Other AbstractThe present invention relates to wireless network resource allocation technology, and specifically relates to a resource allocation method oriented to the coexistence of multiple linear topology industrial wireless networks. The present invention takes the problem of the coexistence of multiple TDMA-based linear topology industrial wireless networks into consideration, and comprises three parts, i.e. a scheduling delay lower bound analysis, an inter-network resource allocation algorithm and an intra-network resource allocation algorithm. In the method, when a delay lower bound is analyzed and a resource allocation algorithm is designed, an overall scheduling delay and a resource utilization rate are taken as measurement indexes, and an optimal node combination is selected in each slot in order to occupy as many channel resources as possible, thereby improving the resource utilization rate and reducing the overall scheduling delay.
