In this paper performance of Simple MAC for various random wait times is evaluated. Design of efficient Medium Access Control (MAC) protocol with high throughput performance and high degree of fairness performance is major focus in distributed contention-based MAC protocol research. Different MAC mechanisms have been proposed for the decentralized MAC. In this paper, the authors study 802.11 MAC's Binary Exponential Back off and Simple MAC which uses random wait time for stations. In this paper, they demonstrate the behavior of Simple MAC for various random wait times and different scenarios of cross traffic with 4 nodes and simple 2 node scenarios in Network Simulator (NS2).
