The use of multiple independent spanning trees (ISTs) for data broadcasting in networks provides a number of advantages, including the increase of fault-tolerance and bandwidth.
Since supporting indices on the broadcast data items can effectively reduce the power consumption of the mobile clients, most of the existing research on data broadcasting has focused on designing efficient indexing schemes.
In this paper we investigate the role of medium access control on the performance of network-wide real-time data broadcasting through flooding using three MAC protocols (IEEE 802.11, CPS, and MH-TRACE) in terms of QoS (packet delivery ratio, packet delay, and delay jitter) and energy dissipation.
Microsoft has built a new national wireless data network, based on the data broadcasting ability of FM radio stations.
Clearwire is pushing hard and fast to become a pioneer of WiMax, a long-range data broadcasting technology pegged as a successor to Wi-Fi, the wireless networking technology that can only be used within a few hundred feet of transmission antennae.
"We see data broadcasting as a critical part of the new generation of cable infrastructure technologies," said Kevin Keefe, director of product marketing for GI's Digital Network Systems business unit.
The use of edge-disjoint spanning trees for data broadcasting and scattering problem in networks provides a number of advantages, including the increase of bandwidth and fault-tolerance.
Some analysts see VBI (vertical blanking interval) data broadcast as another kind of warm-up act in advance of the arrival of digital TV: Not too sexy or particularly versatile, but highly reliable as a way to advance the proliferation of wireless data broadcasting services, sending a constant stream of stock prices, sports scores, news reports and even web pages to both TVs and PCs.
The standard can also be used for transmission of new data broadcasting services.
