Abstract: In today’s modern world, people needs the fastness and efficiency in any system that we considered. So, there is a need for a mechanism which satisfied the needs of network users. Pipelining is a technique that allows the execution of many jobs to overlap in time. Overlapping is accomplished by dividing each job into stages. This study presents concepts of medium access control layer in the IEEE 802.11 Distributed Coordinated Function (DCF). Also, it modifies the medium access control layer mechanism and implementing it in the pipelining technique. The pipelining techniques used are partial pipelining technique and total pipelining technique. In the existing technique one control channel and one data channels are used. The control channel is for contention resolution and the data channel is for transmitting data and to receive acknowledgment. But in the proposed technique two contention resolution channels and one data channel is used.
