Improving the performance of directional medium access control protocols with smart antennas for mobile ad hoc network

In this paper, we conducted a comparison study of the existing directional MAC protocols that use Smart Antennas by contrasting their features. We found that, most of these protocols are not applicable in mobile environment. This investigation discusses the challenges in improving some of these Smart Antenna-based MAC protocols. We proposed to upgrade two protocols, Tone-DMAC protocol and Angular-MAC protocol. We proposed to model the behavior of these two protocols analytically and carry the improvement performance by using two omni-directional control packets. We suggested that using these two packets and Adaptive Array Antennas in the above protocols will make them applicable in mobile environment and as well as improve routing performance. ©2007 IEEE.
