In wireless sensor network applications,location information of sensor nodes is critical in the life of the entire network.It is a hot issues to design localization algorithm with higher accuracy and lower cost.In this paper,we propose an improved DV-Hop localization algorithm that improves the localization accuracy.The method is based on the traditional DV-HOP, the average hop distance calcula...

—Traditional indoor localization method based on the received signal strength (RSSI) has many drawbacks, such as the low localization accuracy, the high hardware requirements, and the complex algorithm. It is essential to create a robust system that can be suitable for varying indoor environment. In order to solve this problem, an automatic calibration indoor target signal positioning system i...

The purpose of this study was to determine whether localization errors were greater in cases of right ear unilateral simulated conductive loss, as compared to left ear simulated conductive loss of the same degree and configuration. Thirty adults were asked to localize a 3-kHz warbled pure tone with their left and right ears alternately occluded with an earplug. Significantly greater localizatio...

Localization is an essential requirement in the increasing prevalence of wireless sensor network (WSN) applications. Reducing the computational complexity, communication overhead in WSN localization is of paramount importance in order to prolong the lifetime of the energy-limited sensor nodes and improve localization performance. This paper proposes an effective Cuckoo Search (CS) algorithm for...

Many source localization methods neglect the anisotropic conductivity of brain tissues, although it has a big influence on the localization problem. In this study, we evaluated the dipole localization error due to neglecting the anisotropic properties of the conductivity in a realistic head model (built from T1 and diffusion tensor MRI) calculated using a FDM method. Results show that the mean ...

The Design of Calamari: an Ad-hoc Localization System for Sensor Networks by Cameron Dean Whitehouse Master of Science in Electrical Engineering and Computer Science University of California at Berkeley Professor David Culler, Research Advisor This thesis describes the design of an ad-hoc localization system for sensor networks. We begin by formulating design principles from a concrete implemen...
