The performance of Ad-hoc network is calculated by the number of packets successfully delivered to the destination. In multi-hop wireless networks, every node acts as middle node to forward packets to other nodes. To increase the overall network performance, number of packets delivered to the destination successfully must be increased. In the congested network the coordination between the active nodes must be maintained to increase network performance .In this paper, the authors discuss medium access protocol, MACA .The Hidden terminal problem and exposed terminal problem had been solved by using MACA. In this paper, they review MACA and highlight the NAV attack which is possible in this protocol.
