Abstract. Wireless sensor network is a suitable technology for ubiquitous environment. However, in WSN, as the network size grows larger, overheads such as flooding, calculation an...
Most of today’s authentication schemes involve verifying the identity of a principal in some way. This process is commonly known as entity authentication. In emerging ubiquitous ...
In this article we describe and evaluate a novel, low interaction cost approach to supporting the spontaneous discovery of geo-tagged information while on the move. Our mobile hap...
The tension between privacy and awareness has been a persistent difficulty in distributed environments that support opportunistic and informal interaction. For example, many aware...
Context-aware applications can better meet users’ needs when sensing agents installed in the environment automatically provide input relevant to the application. However, this n...
