On the Flow Classification Thresholds of FD-MAC Protocol

Flow Driven MAC Protocol (FD-MAC) is a slot based MAC protocol which is designed for long distance wireless multi hop 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 suggest that the Flow Classification Thresholds (FCTs) of the protocol are the key parameters to the performance of the protocol, that are not yet been fully investigated. Then the values 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 achieved when optimal FCT values are chosen.
