Abstract: Because of limited bandwidth capacity in Ad hoc networks, multipath transport is appealing technique to satisfy the requirement of QoS services on bandwidth by improve available bandwidth. In this paper, the feasibility of reasonable distribution for minimization of delay is proved theoretically, and an algorithm of Adaptive Traffic Distribution Based on Minimize Delay(ATDBMD) in Ad hoc networks is proposed, aiming at the minimization of delay and delay jitter, to satisfy another requirement of QoS services on delay. Simulation result shows that ATDBMD wins other algorithm in simpleness, quickly adaptability and precisely control.
