Current developments show that in the near future the wide availability of low cost, short range radio technology, along with advances in wireless networking, will enable wireless adhoc sensor networks to become commonly deployed. In these networks, each node may be equipped with a variety of sensors, such as acoustic, seismic, infrared, motion, biomedical and chemical sensors with higher level of information inference associated with identification, embedded signal processing and networking of the data. This conference intends to be the meeting point of researchers and practitioners to share experiences and ideas on innovative developments in any aspect of sensor networks, including Hardware of Sensor Networks, Wireless Communication Protocols, Sensor Networks Software and Architectures, Wireless Information Networks, Data Manipulation, Signal Processing, Localization and Object Tracking through Sensor Networks, Obstacles, Applications and Uses. http://sensornets.org/
