An Adaptive Medium Access Control Protocol for Computer Network

We applied a dynamic channel allocation scheme to get better utilization when the traffic is unpredictable or fluctuating. In contention resolution approaches if multiple users transmit at the same time a collision occurs and the packets must be retransmitted according to some predefined rule. In random access protocols a transmission is not guaranteed to be a successful one. The challenge of designing an efficient Medium Access Control (MAC) protocol is a big issue. This paper focuses on the performance analysis (through simulation) and modification of a well known MAC protocol. The purpose of this work is to modify the existing protocol by enabling it to adapt according to state of the network and understanding the effect of unpredicted load fluctuations The modified protocol takes appropriate action whenever unutilized periods detected and it should also be In this way, to increase the effective bandwidth utilization and determine how it behaves under increasing load and varying packet sizes.
