Investigation on dynamic channel allocation strategies suitable for PRMA schemes

Among the various packet multiple access schemes proposed for mobile radio operation, packet reservation multiple access (PRMA) method is discussed. The performance of a PRMA scheme in a cellular layout depends heavily on the adopted resource allocation scheme, which is required to keep the mutual interference below the desired limit. Due to its discontinuous transmission and to the high variability of the interference patterns, PRMA cannot control the interference level by simply monitoring the link quality. This evidence makes PRMA operations with dynamic channel allocation (DCA) really difficult to achieve. However, DCA seems to be necessary in microcellular environments, where traditional planning algorithms may fail due to the high complexity of propagation phenomena. The issue of compatibility between PRMA and DCA compatibility are proposed.<
