—Wireless Sensor Networks (WSNs) are being used in a variety of applications including environmental monitoring, event detection, object tracking, and healthcare applications. Network management of WSNs is one of the key practical challenges that arise from the increasing number of applications and technologies deployed. This work presents a web-based(More)
ASWP testbed, a long-term wireless sensor network (WSN) deployment for environmental monitoring, is presented. This testbed integrates 42 MICAz nodes that implement a periodic sampling application for external sensors exposed to a forested nature reserve at the Audubon Society of Western Pennsylvania (ASWP), USA. It has been running for the past two years(More)
This paper presents the levels of copper and zinc determined in a total of 66 samples of the most widely consumed varieties of white and red grapes in Spain, as well as those of 60 samples of grape juice (39 from white varieties and 21 from red ones) chosen from the main commercial brands in the country. Atomic absorption spectroscopy was used as analytical(More)
This paper explores the network performance and costs associated with the deployment, labor, and maintenance of a long-term outdoor multi-hop wireless sensor network (WSN) located at the Audubon Society of Western Pennsylvania (ASWP), which has been in operation for more than four years for environmental data collection. The WSN performance is studied over(More)
This is an investigation of Wireless Sensor Networks (WSNs) using Memsic's XMesh routing protocol on MICAz wireless motes. It focuses on the study of the practical aspects of WSNs' power efficiency and network characteristics, which play a critical role in real-word WSN deployments for environmental monitoring. Based on an experimental study and following a(More)
— In this paper we present MobileDeluge, a general mobile network-reprogramming tool based on Deluge for wireless sensor networks (WSNs). MobileDeluge effectively addresses the weaknesses of Deluge and other traditional over-the-air reprogramming approaches for WSNs. It enables efficient code dissemination for heterogeneous WSN motes regularly operating(More)
