The problem of media sense of 802.21

Dear all,

 

I am a researcher in China working for the handover issue and also a new to the 802.21 community.  I understand that the goal of 802.21 is to provide the integrated wireless networking service among 3G, 2G, WiFi, WiMax, etc., without the interruption of upper layer applications.  So it should be an issue to detect the available wireless network before the handover.  And the necessary information to be probed in advance might include the signal strength, bandwidth, price and the accessibility between the new network and the current used network.

 

Due to my insufficient cultivation in the 802.21 communication, could anyone here show me your pervious work on the topic of media sense please?

 

Thanks!

 

Best regards,
