Short-range and near ground propagation model for wireless sensor networks

Abstract

This paper presents the proposed wireless multipath propagation model based on multipath power delay profile for short-range and near to the ground for the frequencies range of 1 to 3GHz. In wireless sensor networks (WSN) localization algorithm, the propagation model has been used as a function of distance to estimate the range. The multipath phenomenon causes the error in estimation of the received power. Without directly use the received power value to estimate the range, we can increase the accuracy by exploiting the periodicity of the deep fade since multipath behave differently in the certain frequency range.
