Over the past years, the deployment of sensor networks in industrial environments has attracted much attention in several business domains. An increasing number of applications have been developed, ranging from defence, public security, energy management, traffic control to health care. Integration of these sensor networks within domains relying on AAA(More)
Multi-Owner Wireless Sensor Networks consist of devices owned by different entities. They have the purpose of covering large areas and reducing energy consumption associated with transmission over long distances. We propose the use of Virtual Networks with the purpose of grouping resources in a Multi-Owner Wireless Sensor Network and delivering a service to(More)
Over the past years, the deployment of sensor networks in industrial environments has attracted much attention in several business domains. An increasing number of applications have been developed, ranging from defense, public security, energy management, traffic control to health care. Sensor networks are particularly interesting due to their ability to(More)
Environment monitoring is key for multiple applications and requires that devices used in acquiring environment data to be scattered over a wide area, but at the same time maintain accessibility of information from all sensor nodes. Although many Wireless Sensor Networks are based on the IEEE 802.15.4 standard for low-power, Wi-Fi networks offer the most(More)
