Abstract—The use of mobile devices capable of wireless communications such as mobile phones, PDAs, and laptops in disaster recovery has been an important research topic for several years. However, while the majority of previous research has focused on voice and data communications a small number of researchers have proposed the use of multimedia content in aiding with patient diagnosis. Disaster recovery environments often have no or very limited communications infrastructure which poses a challenge to any communications system and makes the delivery of high-quality multimedia content extremely difficult. In order to ensure high-quality sharing of multimedia content between emergency teams a framework that is resilient, reliable, capable of handling dynamic behavior and able to handle multimedia traffic must be devised. This paper proposes a framework that combines peer-to-peer (p2p) streaming, Quality of Service (QoS) predictions, and geographic routing over WiFi wireless mesh networks to transmit high-quality multimedia content between early response teams in disaster recovery scenarios.

Two‐dimensional (2D) videoconferencing has been explored widely in the past 15–20 years to support collaboration in healthcare. Two issues that arise in most evaluations of 2D videoconferencing in telemedicine are the difficulty obtaining optimal camera views and poor depth perception. To address these problems, we are exploring the use of a small array of cameras to reconstruct dynamic three‐dimensional (3D) views of a remote environment and of events taking place within. The 3D views could be sent across wired or wireless networks toJournal of Biomedical Discovery and Collaboration (2009) 4 remote healthcare professionals equipped with fixed displays or with mobile devices such as personal digital assistants (PDAs). The remote professionals ’ viewpoints could be specified manually or automatically (continuously) via user head or PDA tracking, giving the remote viewers head‐slaved or hand‐slaved virtual cameras for monoscopic or stereoscopic viewing of the dynamic reconstructions. We call this idea remote 3D medical collaboration. In this article we motivate and explain the vision for 3D medical collaboration technology; we describe the relevant computer vision, computer graphics, display, and networking research; we present a
