Cool, that's nice.

Before going any further, I should mention that typing out in ALL CAPS  
when writing a mail, is considered as equivalent to shouting. So,  
unless you really do want to appear angry, you should /not/ use ALL  
CAPS.

Now, about your project. Firstly, you need to be more specific about  
your requirements. For example what exactly do you mean by ...

> ->The feature is it should download files from given URL at given time
Does that mean, you should be able to schedule downloads ? So, is the  
download manager, something to just manage and schedule downloads and  
some other external program would actually do the download ?

Also, about this requirement ...
> ->IT SHOULD WORK WHEN SYSTEM IS IN SLEEPING MODE.

What do you mean by "sleeping mode", if you mean the 'sleep' or  
'standby' mode as windows calls it (or the suspend mode as linux calls  
it), AFAIK, doing this is not possible (at least not in the  
traditional sense of 'sleep'), because, 'sleeping' is a device  
specific thing. So, in standby, all devices, incuding the hard disk,  
network card and cpu power down (ie: the CPU stops executing  
instructions, the hard disk spins down and the network card stops  
raising interrupts). Before expalining more, there is something else  
you should know ...

AMP is an old implimentation of power management. AMP has been  
replaced by ACPI. Learn more about APCI and sleep modes (ie: S-states)  
beginning here:

> what i can do for this ?

Since ACPI replaces the old APM implementation and your system  
presumably supports ACPI, you shouldn't need to do anything.

To test if suspend and resume works well on your system, from the  
panel, go to 'System-> Shutdown -> Suspend' and check whether that works
(or from the command line: pm-suspend).

Switching the system back on should return you to the desktop with all  
the state preserved.

So, to summarize:
a. understand what are the limitations
b. define your problem more clearly
