Abstract

The invention discloses a broadband power line communication cross layer dynamic spectrum allocation method. The system according to the method comprises user nodes and available subcarriers which are arranged in a broadband power line network. All the subcarriers are allocated according to the comprehensive link indexes of each user node in the broadband power line communication network, and the node of the maximum comprehensive link indexes acquires the subcarriers. Then the comprehensive link indexes including the number of neighbor nodes, the data packet transmission requirements, data packet average waiting time and the underlying channel characteristics of each user node are considered across layers, and dynamic spectrum allocation of broadband power line communication is realized across layers based on the comprehensive link indexes so that the overall transmission efficiency of the network is enabled to be optimal. The method is reasonable in design, dynamic spectrum allocation of broadband power line communication is realized across layers based on the comprehensive link indexes by facing the common lumped type communication scene in broadband power line communication so that the requirements of practicality and high efficiency of broadband power line communication can be met.

Description

technical field [0001] The present invention relates to the field of electronic information technology, in particular to the field of broadband power line communication, and more specifically, to a cross-layer dynamic frequency spectrum allocation method for broadband power line communication based on comprehensive link indicators. Background technique [0002] With the development of my country's strong smart grid and the further deepening of power system reform, it can be widely used in broadband power line communication in the fields of intelligent sensing and intelligent communication such as smart home, automatic demand response, and four-meter centralized reading. Advantages such as realization cost have been unanimously pursued by industry and academia. [0003] The complex and changeable power line channel environment is still a key factor affecting the transmission quality of broadband power line communication, so dynamic spectrum allocation (DSM) is widely used in b...
