TL;DR: A novel adaptive clustering protocol called the mobile clusters protocol is presented, which uses less control overhead than those proposed thus far, supports node mobility excellently and maintains the stability and robustness of the network architecture.
Abstract: A novel adaptive clustering protocol called the mobile clustering protocol is presented. It uses less control overhead than those proposed thus far, supports node mobility excellently and maintains the stability and robustness of the network architecture. Furthermore, the proposed intelligent control scheme of gateways prevents them becoming bottlenecks between two clusters with different channels. It also avoids gateways missing packets on their non-sensing channels. Simulation and numerical results are shown to confirm the system performance.

TL;DR: 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.
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.
