Problems solved by technology

Compared to the difference in energy consumption for surveillance and communication, mobile sensors suffer from a more severe energy imbalance due to their different motions, i.e. there can be a huge gap in the moving distances of the smallest and largest sensors

Abstract

The invention relates to a mobile balance method for target coverage based on a sensor of a capacity-limited base station, which comprises the following steps of: firstly, dividing target points POIs into left and right arrays of a base station i according to a projection position of the base station i on a straight line, and secondly, selecting a median of each array to calculate a candidate distance; all candidate distances are ranked to form two ordered arrays D1 and Dr; finding a center distance for the ordered arrays D1 and Dr by using an extended median median algorithm, judging whether the center distance is a feasible solution or not through a distance decision algorithm, and updating the minimum movement distance, the left and right arrays and the arrays D1 and Dr on the basis of the feasible solution; and obtaining the minimum displacement distance of the sensor meeting the requirements until the number of the elements of the array D1 and Dr is empty. The method facilitates minimizing the maximum energy consumption of the mobile sensor.

Description

technical field [0001] The invention belongs to the field of mobile sensors, and in particular relates to a mobile balancing method based on the target coverage of a sensor of a capacity-limited base station. Background technique [0002] When using mobile sensors for coverage, the issue of energy efficiency becomes critical. Since the energy to move the sensor is provided by the battery (or other kind of fuel), the battery is consumed during the operation or movement phase of the sensor. Therefore, each sensor can only be active for a limited period of time of its useful life. Once a sensor in the coverage area fails, that coverage area can be destroyed, the lifetime of the coverage area is obviously determined by the sensor with the shortest lifetime, so the task of extending the lifetime of the coverage area (or sensor network) is to make the lifetime the shortest The lifetime of the sensor is maximized. Compared to the difference in energy consumption for monitoring a...
