Farmland environment has influence on the signal propagation of wireless sensor network (WSN). The network coverage and connectivity performances largely depend on the deployment method. In order to prolong the network lifespan, renewable energy was introduced to a part of the network nodes due to the cost issue. An improved energy aware deployment method is proposed in this paper. The aim of the paper is to maximize the network lifespan,lower the network cots, increase the energy utilizationrenewable energy nodes and balance the residual energy of the battery-power nodes. An energy consumption model was established in the consideration of deployment constraints over network coverage, connectivity, and stability. An improved particle swarm optimization (PSO) algorithm was designed to optimize the performance of the network model. A penalty function was included to resolve the problem which contain both continuous and discrete variables.The number of renewable nodes with the best cost-lifespan ratio was concluded. The simulation results demonstrate that the propose method increases the renewable energy utilization when the renewable energy source is good. Also the network keeps stable when the renewable energy source is off. The overall energy consumption of battery nodes were reduced and balanced. Therefore, the proposed deploy method prolong the network lifespan.
