Some examples of broadband mobile wireless applications are:
??? Real-time video: Depending on the usage cases, both full motion and slow scan video
may need to be supported together with video source adaptation as applicable. To meet
the demand for high video bandwidth, a mobile mesh system can benefit from
multicast protocols. Multicasting can provide efficient use of bandwidth by reducing
the number of transmissions compared to separate unicast transmissions to each
recipient in the mesh.
??? Voice over multi-hop mesh: IP-based voice has now been established well over fixed
Internet and is also is finding its way over WLANs. The primary issues concerning
real-time voice are end-to-end delay and delay jitter. In a multi-hop mobile mesh, the
delay jitter might vary significantly and requires appropriate buffering and replay
mechanisms.
??? Instant multimedia messaging: Distributed instant messaging application for peer-topeer
or peer-to-group sessions will be a natural fit in a mobile mesh as presence
information becomes available as soon as a node joins the network. Thus, it is not
necessary to have a central server for authentication or presence indication.
