Taxi is a flourishing industry recently. It plays an important role in many kinds of popular transportation systems because of the characteristic that can be hailed conveniently, and also provided location-based service. Most of the taxi drivers carried passengers by hunting on the road or waiting in a fixed taxi queuing point, but these patterns have poor performance. Furthermore, there are about...
Due to the progress of modern automobiles, using vehicles as sensors to gather information is no longer an unreachable idea. Although the cost of providing services on a specific node is extremely high in Mobile Ad Hoc Network (MANets), to locate a particular node and provide services in Vehicular Ad-hoc Network (VANets) is much easier than in MANets because vehicles are always limited on roads. Particularly,...
Recently, owing to the attentions of environment issues, the environment monitoring technologies and applications are under rapid development. The research on environment monitoring can be divided into two major aspects: sensing data collection and heterogeneous system integration. With the improvement of sensing devices (e.g., precision, sensing range, Internet connectivity, and computation capability),...
XAdvertisements or vouchers are commonly used today to attract the attention and the purchase of consumers by providing discount or detailed description to customers. Typically, vendors use text to describe characteristic introductions and images to express appealing looks. In order to allow consumers to retrieve more information such as location of vendors, an advertisement publishing system should...
Due to recent development in wireless communication networks, researches in Vehicular Ad-hoc Networks (VANETs) have been getting much attention on information sharing and service discovery. However, due to the ever-shifting mobility of vehicle topology, vehicles moving in non-fixed routes may not find suitable next-hop vehicles to pass the data. This paper proposes schemes to effectively circulate...
