Low Rate WPAN MAC Modification to Suit Multi-Beam Smart Antenna Approach
In this paper, the authors concentrate on exploiting the Multi-Beam Smart Antennas (MBSAs) property for the IEEE 802.15.4 MAC Protocol. The MBSA is capable of initiating several data communication by forming spatially separable beams in different directions. With its appealing dimensions, it brings about a new set of challenges. The unique reception and transmission property of MBSA requires an adequate amount of modification to suit the former MAC protocol. They have chosen IEEE 802.15.4 as a platform for their new MAC design with beacon enabled mode, where network coordinator is mounted with MBSA. A coordinator with MBSA boosts up the network performance in the multiple of the number of projected beams. The modified MAC has been simulated using OPNET modeler. The result shows that the performance of the network increases dynamically in terms of delay, throughput and energy consumption.
