ABSTRACT:

Wireless penetration has seen explosive growth over the last two decades. 
Accordingly, wireless devices are much denser per unit area, resulting in 
a crowded usage of wireless resources. Effective coordination among 
wireless stations can dramatically reduce radio interference and avoid 
packet collisions. Therefore, how to provide cost-effective coordination 
mechanisms becomes a critical problem in wireless design.

Motivated by this, we present a novel PHY layer technique termed 
Attachment Transmission to provide an extra control panel with minimum 
overhead. Attachment transmission enables control messages to be 
transmitted along with data packets, and do not degrade the effective 
throughput of the original data packets. We apply attachment transmission 
to a number of classic problems in wireless networks, including 
multi-channel allocation problem, hidden terminal problem and exposed 
problem. Extensive experiments demonstrate that attachment transmission is 
capable of exploiting and utilizing channel redundancy to deliver control 
information, and thus provides significant support to numerous higher 
layer applications. For multi-channel allocation problem, attachment 
transmission provides cost-effective identifier signals. These identifier 
help mobile stations learn the channel allocation strategy by themselves, 
and thus achieve cooperation without coordination.  For hidden and exposed 
terminal problems, attachment transmission provides accurate Channel Usage 
Information (CUI, who is transmitting or receiving nearby) 
with minimum overhead. Therefore, mobile stations can identify hidden and 
exposed nodes  in real time. We believe that attachment transmission can 
be further explored and benefit more communication systems.
