Review Paper of Performance Analysis for Random Access Channel in Wireless Network with MAC Protocol

IEEE 802.11 is a well-known standard for wireless local area networks for both infrastructure Based and Ad-hoc networks. In our research we will work on the MAC layer in wireless network. In these work we will study and analyze the theoretical and mathematical model of Random Access channel in wireless network. Wireless Network Aloha is feasibly the simplest and most-studied medium access control protocol in existence. Earlier study on Aloha using a slotted Aloha, Pure Aloha and OFDMA aloha have shown that the usage trend analysis very much depends on the performance of the multiple channel schemes that divided frequency and time slots. But this algorithm has some disadvantage: It may not increase the throughput performance of a MAC scheme [3], [4]. The first drawback does not only concern pure aloha, but all other algorithms. In this work, we will analyze the performance of the medium access control (MAC) mechanism using IEEE 802.11MAC protocol. IEEE 802.11 is a set of medium access control and physical layer (PHY) specification for implementing wireless local area network (WLAN) computer communication in the frequency bands.
