On the Flow Classification Thresholds of FD-MAC Protocol

A Flow Driven MAC Protocol(FD-MAC) is a slot based MAC protocol which is designed for long distance wireless multihop transmission. With the flow-driven resource reservation mechanism, FD-MAC protocol is especially suitable to be used for wireless ad hoc network with dynamic traffic pattern. We argue that the Flow Classification Threshold(FCTs) of the protocol are the key parameters to the performance of the protocol,which optimal values are not yet been fully investigated. Then the value of the parameters are analyzed theoretically, and the optimal values are given in turn. Simulation result validates our analysis, best performance of the protocol would be anticipated when optimal FCT values are chosen.
