A self-organized reuse-partitioning dynamic channel assignment scheme with quality based power control

High spectrum efficiency is promised by reuse partitioning in a cellular system. We propose an improved algorithm for self-organized reuse partitioning (SORP), a distributed dynamic channel assignment scheme, in order to obviate the need for broadcasting transmit power level information of each mobile terminal. The concept of the improved scheme is simple: a mobile terminal with low transmit power uses a low numbered channel throughout the system. Reuse partitioning can be achieved owing to such a channel segmentation. The algorithm is designed to realize the channel segmentation without the broadcasting of the transmit power level. Computer simulation results show that a high capacity and short delay time in finding an appropriate channel can be obtained. Furthermore, a higher capacity can be obtained by introducing quality based power control into this algorithm
