Message ring-based channel reallocation scheme for cellular networks

Wireless communication suffers from many restrictions due to the inherent limitations of the wireless media and existing wireless communication protocols. Limited radio frequency spectrum (or bandwidth) is one of the major issues in wireless communication. In order to efficiently share the limited bandwidth, different channel allocation (or channel assignment) schemes have been developed. In this paper, we propose a frequency reallocation scheme, message ring-based channel reallocation (MRCR) to improve channel utilization in wireless communication systems. MRCR uses software agents to circulate and maintain a message ring that carries bandwidth information. We present results of simulation studies to demonstrate the effectiveness of the MRCR scheme
