A technology named Carrier Sense Multiple
Access with Collision Avoidance (CSMA/CA) is used to
reduce collisions happened in a network. However, when
network nodes increase, the contention window number may
not be wide enough. It will cause collision probability to
increase. We cannot avoid the chance of collision in a shared
medium. This paper presenting an algorithm that tries to
avoid collision and it also takes action if there is a collision
exists. This single algorithm can be used for collision
avoidance as well as collision detection. If any collision
detected its retransmission policy can be used. It helps to
reduce the waiting time of the stations for initiating
transmission.

This paper presents a new algorithm for accessing a shared
medium. It provides better performance as compared to
other MAC protocols. This algorithm tries to avoid
collisions and also detect if there is any collision exist
during transmission. It can avoid most of the problems of
other MAC protocols. This single algorithm can do the
functionality of both collision detection and collision
avoidance algorithms. As compared to CSMA/CA, this
new approach reduces the waiting time of the stations,
want to transmit.
