Abstract

The invention provides a directed spanning tree cross-layer communication method based on power control, which is characterized in that the method comprises the following steps: first, establishing adirected spanning tree model based on geographical position information; and second, establishing a cross-layer node transmission power control model and solving an optimal node transmission power solution set. The invention adopts a directed spanning tree algorithm to solve the problem of invalid energy consumption in the data transmission process and controls the transmission power of nodes to reduce the network communication competition intensity. Compared with other schemes in the same field, the invention can effectively balance the energy consumption and the reliability of the network communication and meets the requirement of long-time high robustness of a wireless sensor network.

Description

Technical field [0001] Aiming at the communication quality requirements of wireless sensor networks, the present invention proposes a power control-based directional spanning tree cross-layer communication method, which is more suitable for wireless sensor networks, VANET, ad hoc networks, and wireless network communication fields. Background technique [0002] Routing technology Wireless sensor network (hereinafter referred to as WSN) is a typical infrastructure-free wireless communication network. It consists of a large number of low-energy nodes with computational processing, wireless communication and sensing capabilities, and each node is realized by sensing or controlling parameters Interaction with the environment is different from traditional network concepts. WSN has the characteristics of being data-centric, no wired support, and network self-organization. Therefore, it is considered to be the most suitable information processing method for realizing environmental intell...
