(TE) based cooperative forwarding where nodes use
transmission time slots as incentives for relaying. We focus
on distributed joint time slot exchange and relay selection in
the sum goodput maximization of the overall network. We
formulate the design objective as a mixed integer nonlinear
programming (MINLP) problem and provide a polynomial time
distributed solution of the MINLP. We implement the designed
algorithm in the software defined radio enabled USRP nodes of
the ORBIT indoor wireless testbed. The ORBIT grid is used as a global control plane for exchange of control information between the USRP nodes. Experimental results suggest that TE
can significantly increase the sum goodput of the network. We
also demonstrate the performance of a goodput optimization
algorithm that is proportionally fair.
