Performance estimation of a rotation antenna with directional selectivity in IEEE 802.11 wireless networks

Spatially separated antenna devices in wireless communication system determine the effectiveness of the radio network performance. A non-uniform directional antenna mounted for wireless node localisation radiates energy along one particular direction more than others. In this paper, the performance evaluation of a software-controlled wireless antenna system is presented. The specific type of wireless network application with a frequency reconfigurable rotation antenna incorporating the directional selectivity characteristic is employed in the context of IEEE 802.11 wireless networks. The wireless antenna system is tested in terms of various queuing-related metrics of average buffer length, mean queuing time and packet arrival rate. In addition, the quality-of-service (QoS) performance attributes of wireless communication network are estimated, including the packet interference rate, average round-trip delay and application throughput. Furthermore, the efficient performance of our model is significantly compared with the previous works in terms of throughput and delay parameters.
