  The deployment of network nodes is essential to ensure the wireless sensor
network's regular operation and affects the multiple network performance
metrics, such as connectivity, coverage, lifetime, and cost. This paper focuses
on the problem of minimizing network costs while meeting network requirements,
and proposes a corona-based deployment method by using the variable
transmission distance sensor. Based on the analysis of node energy consumption
and network cost, an optimization model to minimize Cost Per Unit Area is
given. The transmission distances and initial energy of the sensors are
obtained by solving the model. The optimization model is improved to ensure the
energy consumption balance of nodes in the same corona. Based on these
parameters, the process of network node deployment is given. Deploying the
network through this method will greatly reduce network costs.
