The development of low-cost image/video sensors has enabled wireless multimedia sensor networks (WMSN). Equipped with the ability to collect images/video streams from surrounding environments, many interesting applications will emerge through the use of WMSN. One of the key targets of a WMSN application is reconstructing the Plenoptic function by using collected images. However, due to the characteristics...
Recent advances in image sensing hardware have enabled the development of wireless image sensor networks. Similar to generic wireless sensor networks that collect information from surrounding physical environments as scalar variables, wireless image sensor networks can collect data to generate descriptions of interested targets as images or video streams that, in turn, enhance the userpsilas understanding...
Haptic interfaces have been designed for brain surgery simulation may prove to be especially useful for training surgeons to conduct minimally invasive procedures and remote surgery using tele-operators. However, it well known that collaborative, haptic, audio and visual environments (C-HAVE) suffer from setbacks due to network delay, scalability, reliability and synchronization problem when the users...
Nowadays, distributed collaborative virtual environments are used in many scenarios such as tele-surgery, gaming, and industrial training, however several challenging issues remain to be resolved before haptic virtual reality based class of applications become a common place. In this paper, we focus upon a tracheotomy tele-surgery application that is based on closely coupled and highly synchronized...
Collaborative virtual environments (CVEs) such as massive multiuser 3D games and military training environments can place strict requirements on networks when participating users share the 3D virtual environment through mobile devices in an ad-hoc network. In this paper, the authors show how a CVE application can benefit from the application layer multicast when deployed on the Gnutella peer-to-peer...
