In today's world of mobility, Mobile Ad-hoc NETwork (MANET) is of utmost importance because it provides connectivity to users while on move. The main issue in Mobile Ad-hoc NETwork (MANET) is of accessing the wireless channel, where too many users try to get access simultaneously. Traditionally, IEEE 802.11 Standards provide two protocols at MAC layer i.e. Distributed Coordination Function (DCF) and Point Coordination Function (PCF). In this paper, a comparative study of PCF and DCF with Distributed Queuing Mobile Ad-hoc Network (DQMAN) and Distributed Point Coordination Function (DPCF) protocols is presented.
