Embodiment Construction

[0037] The present invention will be further described below in conjunction with accompanying drawing.

[0038] The present invention mainly proposes a method for deploying a directional charging base station of a wireless rechargeable sensor network. All rechargeable sensors have the same specifications except for their respective power consumption. A sensor can only be charged by a directional base station. The specifications of the directional charging base stations are also the same. The base stations can only charge one sensor at a time, but they can charge different sensors at different times within a period of time by rotating the direction of the charging antenna. On a H*W two-dimensional plane, N rechargeable sensors are randomly deployed. On the premise of ensuring that all sensors in the entire sensor network can continue to work, it is necessary to find a deployment strategy for directional base stations, and make the number of base stations in the deployment str...

Abstract

The invention discloses a directional charging base station deployment method of a wireless rechargeable sensor network. According to the wireless rechargeable sensor network adopted by the invention, N rechargeable sensors are randomly deployed in a two-dimensional plane; according to the adopted wireless charging model, a directional base station only can charge one sensor at a moment, through rotating the direction of a charging antenna, different sensors can be charged at different moments in a time period, and moreover, one sensor only can be charged by one directional base station. The specific steps are as follows: 1, solving a sensor set with feasible base stations; 2, solving a candidate base station set corresponding to the result set RFS of the sensor set; 3, calculating appearing frequencies of the sensors; and 4, selecting the base stations from the candidate base stations as few as possible. According to the method, through combination of the time divided charging models of the rotary directional charging base stations, the method conforms to the practical application scene well; and through adoption of two heuristic algorithms based on cupidity, the operation speeds of the algorithms are improved.

Description
