Improved Optimal Slotted CSMA/CA Protocol

Abstract

This research work focuses on designing an optimal slotted CSMA/CA. The main motivation is the cycles wasted in un-slotted and slotted CSMA/CA. So to reduce wasted cycles a new technique is proposed in this research work which use adaptive slots also called optimal slots for Slotted CSMA/CA handles collision by reducing the wasted cycles The proposed protocol is designed and implemented in MATLAB. The simulation has shown significant improvement over slotted and un-slotted CSMA/CA based upon some performance parameters. General Terms Mobile Ad hoc network, Optimal Slotted CSMA/CA protocol. Keywords Carrier Sense Multiple Access/Collision Avoidance(CSMA/CA) Request-To-Send (RTS), Clear-To-Send (CTS),Acknowledgement(ACK).
