Abstract

The invention discloses a low-power-consumption wireless-sensor-network optimization method based on program analysis. The method includes: step1: setting up a wireless-sensor-network cluster; step2: performing program analysis; step3: optimizing function scheduling; step4: optimizing a basic block level. The low-power-consumption wireless-sensor-network optimization method carries out power-consumption optimization on wireless sensor networks through use of the result of the program analysis and realizes an objective of reducing the power consumption of the wireless sensor networks through effective scheduling of an inline function which has the highest calling frequency.

Description

technical field [0001] The invention relates to the field of wireless sensor network communication, in particular to a method for optimizing a wireless sensor network based on program analysis. Background technique [0002] The wireless sensor network (hereinafter referred to as WSN) requires a survival time of several months or years. The nodes are generally powered by batteries with limited capacity, and it is inconvenient to replace the batteries. On the premise of maintaining performance, how to save energy and prolong the running time is a important challenge for its application. [0003] Embedded system power consumption optimization first focuses on the hardware level, including the circuit level and RTL level. The higher the level, the greater the energy consumption space and the higher the design cost. Since hardware-level power consumption optimization has encountered a bottleneck, software-level power consumption modeling and optimization provides a new way to sa...
