Abstract

The invention discloses a method for efficiently scheduling multiple batteries supplying power for a wireless sensor node, and belongs to the field of energy management of wireless sensor networks. According to the technical scheme, (1) a ZigBee module is adopted as a wireless communication unit of the wireless sensor node, and a microprocessor, a data sensing module, a power module, a power managing module and an energy collecting module are arranged additionally; (2) a linear programming algorithm is adopted as a method for scheduling the multiple batteries of the wireless sensor node, wherein (a) the maximum rest time of each battery for restoring a charge unit is set as Ti; (b) a binary function Pi (Qn, Rt) describing the restoration capability of each battery is set, wherein Qn represents the number of the current charges of each battery, and Rt represents the restoration times of each battery; (c) current charge number tolerance difference values Qtd among the multiple batteries are set. The method for efficiently scheduling the multiple batteries supplying power for the wireless sensor mode has the advantages of being suitable for most application environments and organizing structures of the wireless sensor networks, and capable of effectively prolonging the service life of the wireless sensor node.

Description

technical field [0001] The invention belongs to the field of wireless sensor network energy management, in particular to a multi-battery-powered wireless sensor node and an efficient scheduling method thereof. Background technique [0002] In the past ten years, with the development and maturity of related technologies and processes, wireless sensor networks have developed rapidly, and their applications have become more and more extensive. The research and development of wireless sensor networks has become a hot spot in the information field. Sensor networks are generally composed of a large number of micro-sensors deployed in a certain area. Such micro-sensors are generally powered by batteries and will not be replaced after deployment or require a lot of manpower and material resources to replace them. Therefore, energy has become the primary solution for sensor networks. [0003] At present, due to the limitation of battery manufacturing technology, it is difficult to ac...
