Node Deployment of Wireless Sensor Networks Based on MOEA/P Algorithm

Node deployment is one of the most important research directions of WSN, and it is the precondition that wireless sensor network can realize the predetermined function. Reasonable node deployment strategy can optimize the topology of the network, improve the overall energy efficiency of the network, improve the service quality of the network, and also a prerequisite for a long life cycle. The research of sensor network node deployment technology has extremely important theoretical and practical value. Wireless sensor node deployment is defined as the multi-objective optimization problem, which can ensure the maximum network connectivity, maximize network coverage, minimize the total network energy consumption, minimize network cost and maximize the network life cycle. This paper focuses on the deployment of sensor nodes in two-dimensional planar area. Based on the multi-objective optimization MOEA/P algorithm, the node deployment scheme is realized, which can maximize coverage area and minimize cost. The experiment shows that the algorithm can effectively solve the multi-objective optimization problem in wireless sensor network deployment.
