Localization is a fundamental and essential issue for wireless sensor networks (WSNs). In this paper, a three-dimensional localization scheme, iterative calculation of secondary grid division localization scheme (ICSGDLS), was proposed for wireless sensor networks. In this scheme, forty beacon nodes and five hundred unknown sensor nodes were randomly deployed in a cube, which is divided into smaller...
Wireless sensor networks have spread widely in the recent years. They have a very wide range of applications such as environment monitoring and military applications like battlefield monitoring. Sensors and their data are vulnerable to various attacks, like data injection, deletion, modification or even node replacement. Because of the resource limitation, security mechanisms that are based on traditional...
The underwater target localization problem is one important application for underwater acoustic sensor networks. This paper, based on "underwater acoustic transmission theory", solves the target localization problem. The proposed algorithm firstly studies the principle of underwater acoustics and applies it to set up the model of underwater signal energy transmission. According to the model,...
This paper presents a distributed fermat-point range estimation strategy, which is important in the moving sensor localization applications. The fermat-point is defined as a point which minimizes the sum of distances from three sensors inside a triangle. This point is indeed at the trianglepsilas center of gravity. We solve the problems of large errors and poor performance in the bounding box algorithm...
