WSN obstacle area coverage deployment method of artificial bee colony algorithm adopting problem characteristics

Abstract

The invention discloses a WSN obstacle area coverage deployment method of an artificial bee colony algorithm adopting problem characteristics, and the method specifically comprises the following steps: dividing a monitored area into a point set Ra, setting an obstacle area as an uncovered point set Ro, and setting an area to be covered as a point set Rc = Ra-Ro; initializing artificial bee colony algorithm parameters (including population number, problem dimension, maximum cycle times and food source non-update times), and performing employment bee, following bee and investigation bee processes in artificial bee colony algorithm cycles. The invention has the beneficial effects that a linear change parameter and a problem dimension are introduced into the global search part of the candidate formula, the part is weakened along with the increase of the number of iterations and the improvement of the problem dimension, and the improved search method is adopted in the employed bee stage and the following bee stage; therefore, the algorithm can adaptively balance the global and local search capabilities, and the algorithm can fully explore the search space in the early stage and can converge at a high speed in the later stage.

Description

technical field [0001] The invention relates to a WSN obstacle area coverage deployment method, specifically a WSN obstacle area coverage deployment method using an artificial bee colony algorithm with problem characteristics, and belongs to the technical field of Internet of Things applications. Background technique [0002] Wireless Sensor Network (WSN) is a multi-hop self-organized information perception, collection and transmission system, which can obtain detailed and accurate data in a variety of environments, and realize information interaction between people and the objective world. WSN coverage essentially expresses the network's ability to monitor target areas. At the same time, the coverage rate is also a criterion for evaluating the quality of service provided by the wireless sensor network. The coverage problem of complex area belongs to NP-hard problem, artificial bee colony algorithm is often used to solve this kind of problem. There are two types of problem...
