摘要
区域覆盖是一个难以解决的问题,特别是在广阔的区域。在针对该问题提出的解决方案中,有随机部署和确定性部署两种类型。在感兴趣区域(Area of Interest, AoI)限制上配置了确定性部署的缺点,在感兴趣区域(Area of Interest, AoI)上配置了随机部署的缺点。这个问题会影响功耗和连接性;因此,它会影响感兴趣区域的覆盖范围。在本文中,我们提出了第三种类型的混合部署,它集合了随机部署和确定性部署的优点并最小化了它们的缺点。这种类型有两个步骤;预期配置步骤和调度过程步骤。通过对比研究,证明了该类型在利益范围广、风险小、利益多的情况下优化覆盖的有效性。
Area Coverage Optimization in Wireless Sensor Network by Semi-random Deployment
Area Coverage is a difficult problem to solve with a minimum number of sensor nodes for maximum time duration, especially in wide areas. Among the solutions proposed for this problem there is the deployment with its two types random and deterministic. The disadvantages of deterministic deployment are configured in the Area of Interest (AoI) limitation, and random deployment is configured in the non-equitable distribution of sensor nodes on AoI. This problem affects power consumption and connectivity; as a result, it affects the coverage of the area of interest. In this paper we have proposed a third type of hybrid deployment that gathers the advantages and minimizes the disadvantage of the application of the random deployment and deterministic deployment. This type has two steps; the anticipate configuration step and the scheduling process step. A comparative study was done to show the effectiveness of this type to optimize coverage in the vast area of interest less danger and more interests.
