Wireless Sensor Networks (WSN) differ from traditional wireless communication networks in several characteristics. One of them is the power awareness since the batteries of sensor nodes have a restricted lifetime and are difficult to be replaced. Therefore, all protocols must be designed to minimize energy consumption and to preserve the longevity of the(More)
A caudal block is currently performed in children. A randomized and double blind study including two dosages of fentanyl: 0.5 (group I) and 1 (group II) in association with bupivacaine 0.25% at a dosage of 1 was carried out. Two groups of 25 children undergoing urogenital or orthopaedic surgery participated in this(More)
Wireless Sensor Networks (WSN) consist of sensor nodes with sensing and communication capabilities. Since sensor nodes are energy constrained and sensor data are subject to several sources of errors, the use of a quorum mechanism to achieve consensus leads to higher data accuracy. In this paper, an Event Clustering Routing Protocol based on Consensus(More)
