A novel idea of spectrum management (SM) using spectrum load balancing (SLB) algorithm

摘要

Next Generation Network (NGN) is troubled by the difficulty of growing demand for the spectrum, to resolve the problem, it is possible to find a more efficient way in using the existing spectrum bands and technologies. The radio spectrum can be expressed in three dimensions: frequency, space and time. If any one of these differs between transmitters, interference should not occur. At present, the spectrum sharing (SS) technology is gaining concentration and dissimilar strategies are being studied to allow different operators to share the spectrum in opportunistic way and at the same time gain higher spectrum efficiency. The intention of this paper is to equalize the total distribution of the allocated radio spectrum resources among more interfering devices that work in the same space. Mitigation of the destructive, mutual interference in the wireless network can be achieved with the application of the spectrum load balancing (SLB) algorithm. This enables an equally-smoothed allocation of the spectrum by redistributing, with respect to their individual QoS requisites, and optimized use of the obtainable spectrum. In fact, it permits the detection of the unused spectrum, which was initially licensed, and to release it if it is needed again.
