Design of Sequencing Medium Access Control to Improve the Performance of Wireless Networks

This paper presents a technique for accessing channel based on sequencing technique for 802.11 wireless networks. The objective of this method is to reduce, as well as to avoid the number of collisions while accessing channel by many nodes at the same time. A concept of sequence number is introduced to avoid collisions. The transmission of a node takes place after checking the sequence number. MAC layer issues are very important while accessing channel over wireless networks. Simulation results show that the performance of sequence MAC is improved significantly when compared with legacy MAC.
