Abstract

The invention discloses a method and a device for charging a wireless network sensor, and relates to the technical field of wireless communication. The method and the device can be used for solving the problem of large charging energy consumption of WCV on the premise of ensuring the charging efficiency. In an embodiment of the invention, a base station receives position information of each node in a wireless sensor network WSN; the base station divides the WSN into at least two areas according to the position information of each node, wherein the longest distance from the center of each area to the edge of each area is the longest charging distance of a wireless charging vehicle WCV; the base station determines an initial charging path of the WCV according to the position of the center of each area; and the base station controls the WCV to respectively park at the center of each area according to the initial charging path and simultaneously charge all nodes within the current parking area. The scheme provided by the embodiment of the invention is suitable for charging nodes in the WSN.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a charging method and device for a wireless network sensor. Background technique [0002] At present, WSN (WirelessSensorNetworks, wireless sensor network) is a wireless network composed of a large number of stationary or moving sensors. The sensor nodes in the traditional WSN are powered by batteries, but the battery power is limited and cannot be replaced, which will cause sensor The energy of nodes is limited, so the network lifetime of WSN is limited. [0003] In order to solve the problem of limited node energy, a WCV (wireless charging vehicle, wireless charging vehicle) can be dispatched in a wireless sensor network with several sensor nodes, so that the WCV can run periodically in the wireless sensor network area. The nodes are charged so that the WSN can operate normally. As the density of sensor nodes increases, the number of sensor nodes that need to b...
