QoS enabled routing makes the utilization of resources more efficient by minimizing the unnecessary control messages and should not allow the transmissions that cannot meet the given QoS requirements. Due to the limited bandwidth constraint and dynamic topology of MANETS, supporting QoS is a challenging task. To improve the amount of unconsumed bandwidth and to reduce the overhead associated with the channel contention in MAC (Medium Access Control) layer, log based pipelined concept is applied to back-off procedure. Due to this logarithmic pipelined concept, channel waiting time is reduced.
