Abstract:
Efficient data dissemination in distributed systems is a challenge that can be tackled by sharing common data
and processing results among multiple queries. Doing so in an effective manner helps to save network bandwidth
and computational resources. This is especially important in embedded networks where such resources
are often extremely scarce. Disseminating resource-intensive XML data in embedded networks has been enabled
by using binary XML technologies such as W3C’s EXI format. In this paper, we show how filter-enabled
binary XML dissemination in embedded networks helps to further reduce resource demands. Thus, through
the suitable placement of pre- and post-filters on binary XML data, bandwidth on network connections and
computational resources on nodes can be saved. Consequently, more data can be processed with a certain
amount of available resources within an embedded network.
