 Annotation Based Multimedia Streaming Over Wireless Networks Ödevi
|
|
Recent deployments of metropolitan scale wireless access
in various cities and the perspective of future proliferation of
free wireless hotspots, have created tremendous opportunities
for streaming multimedia content over the wireless network.
At the same time, we are witnessing an increased adoption of
wireless technology in portable devices: PDAs, cell phones,
but also more recently mp3 and video players. The main drawback
of this technology is the limited battery life associated
with wireless enabled devices. These devices are increasingly
being used in content (multimedia) delivery over the network.
However, battery technology does not match the advances
afore mentioned, remaining a limiting factor of operating life
in portable devices. The main power consuming components
of a handheld device are the CPU, display and network
interface. The wireless network interface (card) accounts for a
large if not the largest percentage of battery power in such
devices (up to 50% for handheld devices and slightly less
for laptops). Multimedia applications further aggravates the
situation, being both CPU and network intensive.
Upon analyzing the IEEE 802.11 protocol and the data
transfers occurring during a streamed content, we come easily
to the conclusion that the protocol is not optimized for
constant, periodic transfers as in streaming, but for sporadic,
smaller transfers. Therefore, the built-in power management of
802.11 does not succeed in taking full advantage of the idle
periods during the transfer.
Various research has attempted over years to minimize the
power consumption for the network interface. Some have
looked at improving upon the default IEEE 802.11 power
management built-in, others have proposed new power policies Recent deployments of metropolitan scale wireless access
