Abstarct: Wireless sensor networks are a set of connected sensors in which each sensor node is able to collect some information, process, store, and if necessary communicate with other sensors. One of the main design aspects of Wireless Sensor Networks (WSNs) is the deployment strategy of the sensors. The deployment of the sensor represents the cost and capability of detecting a sensor network.deployment of the Wireless sensor networks should consider both the coverage and connection issues. Select a Deployment Type, Depending on the type of sensors, the program and the environment in which the sensors work. In this paper, the classification of sensor network deployment is expressed in terms of the Sensing field. Also, four different sensing fields with obstacles have been created And then by the genetic algorithm, the location of the sensors, the connection between them and the sensor detection radius are shown. Finally, the proposed algorithm is compared with previous algorithms and the results show that the proposed algorithm requires fewer sensors to achieve full coverage and connective than other methods.
