Abstract

Adaptive antenna technology is now regarded as one of the hot-point research areas in mobile communications. However, its applications in mobile stations receive little attention. This paper considers the performance of a multi-hop packet radio network employing adaptive antennas at the mobile stations. A simple adaptive beamforming policy is presented. Analysis and simulation indicates that mobile stations in packet radio networks employing mobile adaptive antennas can offer a significant performance enhancement when compared with their omnidirectional counterparts. In addition, an AD-ALOHA protocol for the MAC layer and the adaptive protocol architecture with adaptive antenna technology was proposed
