Abstract
With the rapid development of microelectronics technology, wireless communication technology and sensor technology, micro-structured sensors that can sense and communicate at the same time have emerged. This tiny device can sense all kinds of information in the surrounding environment, collect it to the sink node, and then transmit it to the data center. Wireless sensor networks are widely used in civil, industrial, agricultural, military and other fields. In order to meet the demand of monitoring area coverage effect, this paper firstly analyzes the research status of wireless sensor networks at home and abroad, points out the main problems existing in the current research process, and establishes a reasonable mathematical model according to the research status. Secondly, to solve the problem of poor coverage effect of existing algorithms, a monitoring area coverage optimization algorithm based on perceived probability around nodes is proposed. By designing a reasonable scheme of moving nodes, the algorithm can gradually disperse the nodes and improve the coverage effect in the monitoring area. Finally, the simulation results show that the algorithm has a good performance, which can reduce the moving distance of nodes, improve the coverage of the network and prolong the service time of the whole network.
