The use of mobile nodes to collect data in a Wireless Sensor Network (WSN) has gained special attention over the last years. Some researchers explore the use of Unmanned Aerial Vehicles (UAVs) as mobile node for such data-collection purposes. Analyzing these works, it is apparent that mobile nodes used in such scenarios are typically equipped with at least(More)
Wireless Sensor Networks (WSNs) can be used to monitor hazardous and inaccessible areas. In these situations , the power supply (e.g. battery) of each node cannot be easily replaced. One solution to deal with the limited capacity of current power supplies is to deploy a large number of sensor nodes, since the lifetime and dependability of the network will(More)
This paper presents a middleware infrastructure for integration of heterogeneous embedded devices in ubiquitous computing environments. The proposed infrastructure employs the Devices Profile for Web Services (DPWS) as the underlying integration technology, allowing devices that adopt different networking standards to interact with each other, through the(More)
