Webbe designed. Current MAC protocols, such as the IEEE 802.11 standard for Wireless LANs, assume the omni-directional antenna at its Physical layer and thus do not fully exploit the capabilities of a directional antenna. In this thesis, we propose a MAC protocol for wireless ad hoc networks which fully exploits the potentials of directional antennas. http://www.tcs.hut.fi/Studies/T-79.7001/2007SPR/blerta_revised_paper.pdf
