Using wireless sensor networks is an effective way of gathering data and also opens up new sensing opportunities. Wireless sensor networks can be more useful if the data can be effectively retrieved from the sensor network. This paper describes the development of a gateway node for a wireless sensor network, implemented in TinyOS, using the AT91RM9200 ARM evaluation kit from Atmel. This node enables...
One application for wireless sensor networks (WSN) is the condition monitoring of high voltage power transformers to actively monitor, predict and identify causes of failures. This paper details a prototype design and testing of a hybrid power management system for a wireless sensor mote. The sensor mote, mounted on the outside of a high voltage transformer, utilizes a piezoelectric cantilever to...
Energy efficiency is a major concern in wireless sensor networks (WSNs). Many clustering algorithms have been proposed for such a purpose. This paper investigates the existing clustering algorithms. The algorithms have been classified and some representatives are described in each category. After analyzing the strengths and the weaknesses of each category, an important characteristic of WSNs is pointed...
Wireless sensor networks (WSNs) usually have a high node density, which makes it unnecessary to require all nodes to be continually active. Scheduling different nodes to be awake at different times saves energy for WSNs. However, traditional scheduling algorithms do not consider the directional data traffic towards the sink and maintaining coverage of the entire network, making them fail to optimize...
