摘要：

Among the large number of contributions concerning the localization techniques for wireless sensor networks (WSNs) there is still no simple energy and cost efficient solution suitable in outdoor scenarios In this paper a technique based on antenna arrays and angle-of-arrival (AoA) measurements is carefully discussed While the AoA algorithms are rarely considered for WSNs due to the large dimensions of directional antennas some system configurations are investigated that can be easily incorporated in pocket size wireless devices A heuristic weighting function that enables decreasing the location errors is Introduced Also the detailed performance analysis of the presented system is provided The localization accuracy is validated through realistic Monte-Carlo simulations that take into account the specificity of propagation conditions in WSNs as well as the radio noise effects Finally trade-offs between the accuracy localization time and the number of anchors in a network are addressed (C) 2010 Elsevier Ltd All rights reserved
