论文摘要
网络节点的部署对于确保无线传感器网络的常规操作至关重要，并影响多个网络性能指标，例如连接性，覆盖率，寿命和成本。本文着重于在满足网络要求的同时最大程度地减少网络成本的问题，并通过使用可变的传输距离传感器提出了一种基于Corona的部署方法。基于对节点能源消耗和网络成本的分析，提供了一个优化模型，以最大程度地减少单位面积的成本。传感器的传输距离和初始能量是通过求解模型获得的。改进了优化模型，以确保同一电晕中节点的能耗平衡。基于这些参数，给出了网络节点部署的过程。通过此方法部署网络将大大降低网络成本。
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.
