Optimization of deployment in a wireless sensor network to achieve full coverage and connectivity

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 aspect of design in wireless sensor networks is the problem of sensor deployment.The deployment of the sensor represents the cost and capability of detecting a sensor network.The deployment of the sensor network should take into account both the coverage and connection issues.In this paper, the types of deployment ofthe sensor network are classified in terms of the sensing field. Also, four different sensing field with obstacle were created and then displayed by genetic algorithm, location of sensors, the relationship between them and the detection radius.Finally, the proposed method is compared with the previous methods and the results show that the proposed method requires less sensors to achieve coverage and connectivity than previous methods
