Abstract

In this paper we introduce a new MAC protocol called Continuous Contention-Assisted Transmission (CAT) for wireless Ad-hoc network. This proposed protocol is based on Carrier sense multiple access with collision avoidance (CSMA/CA) but we have modified the ACK packet and re-designed mobile stations behavior so that they could continuously transmit data without contention. Our proposed algorithm tries to keep collision in the network as low as possible by allowing wireless stations to form a sequence of transmission among stations that have data to send. Analytical results are compared with simulations. The analysis model is quite accurate in predicting network throughput.
