Abstract
This paper deals with some of the main problems that affect directional antenna ad hoc networks, especially deafness and collisions. By means of a thorough study of the possibilities offered by an antenna array, we propose cooperation as a novel technique for deafness suppression, together with a low complexity multiuser detector and a collision avoidance algorithm tailored for this type of networks. Building on these ideas, a new family of protocols (called Cooperative MAC) is designed. A lower and an upper bound on its performance are compared with the Circular RTS/CTS protocol (CRCM), a known benchmark in this field. We are able to achieve interesting improvements.
