A Fuzzy Logic MAC Protocol

In Ad hoc networks,the low priority flows have significant influence on high priority flows because the cooperative mechanism does not exist in medium access control(MAC) layer.To resolve the problem,a new MAC protocol based on fuzzy logic is proposed.It can protect the high priority flows maintain high end-to-end throughput and low delay under heavy background loads,through cooperating relative flows using fuzzy logic mechanism in MAC layer.The new protocol can better protect the end-to-end delay and throughput of high priority data flows when the networks' background load is over 20% in simulation.
