Re: [802.21] Power Management over heterogeneous HO

I think there will be an improvement to the power management. For example, different network interface has different energy consumption in data transmission. Network A may cost less energy per byte but the bandwidth is narrow. Network B has the board bandwidth but the power management is inefficiency. Thus, when an 802.21 client enters into the intersection area of Network A and Network B, the client may prefer network A for the background download service, and prefer Network B for the video service.

Subject: Re: [802.21] Power Management over heterogeneous HO

Hi all,

I am also interested to the topic of power management in heterogeneous networks. I suppose there is an optimal trade-off among power consumption, network delay and throughput, due to the selection of network. Would anyone here show me your works/considerations on the topic?

Thanks!

Sincerely yours,

Hi all, just need to raise the interest of this issue on the mailing list.

While looking at the 05 draft, one issue occurs in my mind. As shown
in the Subject line, I think we should consider how the mobile station
with multiple wireless interfaces can consume its power consumption as
efficient as possible. Very simple scenario is to enable all wireless
interfaces regardless of link connection. Whenever detecting a new
wireless link, the selected interface can be an alternative interface
of vertical handover. However it is toooo much expensive and
unexpected scenario to be adopted on the real networks and even
commercial model. To me, still existing document does not take care of
that deeply, so I'd need to make our efforts on this issue...One
suggestion is to take a wide-coverage tip for notifying the overapped
region such as GPS and even Cellular Positioning Service. I am not
sure these are in-scope of 802.21 though...

Any idea ?
