Abstract
This paper mainly studies the optimization of low power wireless sensor networks. Firstly, the concept and characteristics of Internet of Things and wireless sensor network are introduced, and the problems in low power consumption are analyzed in detail. Secondly, the corresponding optimization strategies and solutions are proposed respectively from the aspects of sensor node energy consumption, transmission energy consumption, network topology, data quality, reliability and delay. The energy consumption of sensor nodes can be optimized by using low power chip and dynamic power adjustment. The optimization of transmission energy consumption and network topology can be solved by selecting suitable transmission scheme and optimizing network topology structure. Data quality, reliability and delay optimization can be improved by means of data pruning, node switching, route optimization, etc. The research in this paper can provide useful reference for the design and implementation of low-power wireless sensor networks, and also promote the development of the Internet of Things.
