| Abstract: | A mobile Ad Hoc network(MANET)is a collection of wireless mobile nodes dynamically forming a temporary multiple-hop network without the use of any central controller or existing net-infrastructure.Based on power controlled multiple access protocol(PCMA),a MAC protocol without head-of-line blocking(PCMA+)and(S-PCMA)were analyzed.It presents a particular analysis to the idea,the mechanism,the effect to the network performance for the(PCMA +)and(S-PCMA). |
