IEEE 802.11 wireless media random access protocols uses binary exponential back-off in time domain to coordinate multiple accesses. Every frame must undergo channel contention before transmission which incurs severe inefficiencies in channel utilization in hidden terminal and multi-hop networks because more than 50% of the total time, stations are waiting to gain channel access. Furthermore, th...

a r t i c l e i n f o Do congestion externalities offer a reason to depart from complete price stability as the only goal of monetary policy in a New Keynesian model featuring search frictions, and under what conditions is the welfare cost of labor-market distortions sizable?
