This paper presents a detailed analysis of Wr@p1 technology (Web Ready Appliances Protocol, formerly Power Modulation), an ultra-low-cost powerline communication solution conceived for the electrical appliance market. Wr@p technology aims at making household appliances capable of network communication without significantly affecting their industrial cost. This may foster the diffusion of “smart” appliances...
Recently, radio frequency identification (RFID) systems have gained popularity in manufacturing units, inventory, and logistics, as they represent an inexpensive and reliable solution for automatic identification. Moreover, RFID transponders are expected to become a key element in the ubiquitous computing scenario. Tags will likely be used to collect sensors data, enabling noninvasive environment...
In the context of cognitive agent programming frameworks, a main research effort accounts for exploiting goal-orientation for specifying and enacting agent interaction. Existing research work focuses almost totally on direct communication models, typically based on speech-acts and FIPA ACL. In this paper we focus instead on mediated interactions, and in particular on interaction taking place in artifact-based...
Recently RFID (radio-frequency identification) systems have gained popularity in manufacturing units, inventory, logistics, as they represent an inexpensive and reliable solution for automatic identification. RFID tags are expected to become a key element in the future ubiquitous computing scenario. Low-cost passive (i.e. featuring no batteries) tags are supposed to play a major role in this context...
This paper discuss the development of a low-cost, narrow-band transmission system, aimed at connecting digital appliances to a home network. The proposed approach is based on powerline communication (ULP: ultra low-cost powerline), carried out on the power-supply wire between the appliance and the outlet. Through ULP, appliance can communicate with a transceiver node located at the outlet, the "smart...
