Abstract

The invention discloses an energy consumption minimization-based serial energy collecting method which comprises the following steps: a first step of network initialization, a second step of network initial energy collection and information transmission, a third step of optimal distribution of network time and a fourth step of a network transmission phase. An energy consumption minimization principle is adopted to design a new wireless power supply and communication network model, a solution for allocating time for information transmission and energy collection of a network is optimized, reliable information transmission can be realized via wireless communication nodes of the network while energy consumption is minimized, requirements for electric energy storage capacity of the wireless communication nodes can be effectively lowered, hardware costs can be reasonably lowered, and an aim of improving network user node energy collection efficiency and energy utilization can be attained.

Description

technical field [0001] The invention relates to an information transmission and energy collection method under a wireless communication network, in particular to a serial energy collection method based on energy consumption minimization, and belongs to the technical field of wireless power supply communication network. Background technique [0002] Energy efficiency is a severe challenge for the next generation of wireless communication networks. As this issue is raised, wireless power supply communication networks have attracted extensive attention from scientific researchers. In this research field, energy harvesting technology mainly refers to the technology that converts heat, vibration, light, electromagnetic waves and other trace energy around it into electricity. Its core idea is to use the trace energy that is usually discarded as much as possible to provide power for sensor nodes or other low-power wireless communication nodes.
