摘要:

无线传感器网络由大量廉价、微小的传感器节点组成,用于军事环境控制、自然事件记录、交通监控、机器人导航等。这样的网络面临着能耗、路由、覆盖、可靠性等各种挑战。这些问题中最重要的类型是源于节点能量消耗受限的覆盖问题。为了解决这个问题,人们提出了不同的方法,其中大多数是基于理论方法,并使用非平衡和计算分布。在所有提出的方法中,使用了大量的节点。在本文中,我们的尝试是基于使用几个传感器,以覆盖广阔的环境区域。我们提出了一种算法,将所需的环境划分为几个区域,并在每个区域中使用遗传算法提高覆盖率。在MATLAB软件中对该方法进行了仿真,并与现有算法进行了比较。实验结果表明,该算法与已有算法相比,具有较好的覆盖率.

英文摘要:

Wireless sensor networks consisting of great number of cheap and tiny sensor nodes which are used for military environment controlling, natural events recording, traffic monitoring, robot navigation, and etc. Such a networks encounter with various types of challenges like energy consumption, routing, coverage, reliability. The most significant types of these problems are coverage that originated from the nodes energy consumption constrained. In order to dominate this problem different kinds of methods has been presented where the majority of them based on theoretical methods and used unbalanced and calculated distributions. In all of the proposed methods a large numbers of nodes are used. In this paper our attempt is based on using a few numbers of sensors in order to cover the vast area of environment. We proposed an algorithm that divides the desired environment to several areas and in each of these areas by using the genetic algorithm improve the coverage. The proposed method is simulated in MATLAB software and the obtained results are compared with the existing algorithms. Results show that the presented algorithm has a substantial coverage in compare with its previous counterparts.
