Infrastructureless networks are the collection of two or more nodes, which are connected in decentralized manner for enabling wireless communication. In infrastructureless networks any node can move at any time so these types of networks require routing protocols those have dynamically changing topology. There are many approaches have been proposed by researchers to improve the system performances of infrastructureless networks. These approaches include the use of directional antennas & power control mechanisms. Actually, directional antennas could be used for transmitting as well as receiving but mostly researchers consider only directional transmission. In this paper, a power controlled directional medium access control protocol has been proposed, which enables both directional transmission and reception of data and control packets.
