Initial Ranging for Prioritized Network Entry in IEEE 802.16 Network
Prioritized network entry is desirable for establishing preferential network
connectivity for the higher priority users when different priority users exist
over a given network. In line with such desirability, we propose a simple but
efficient priority differentiated initial ranging mechanism considering an
Orthogonal Frequency Division Multiple Access (OFDMA) based IEEE 802.16
network. In the proposed mechanism, we introduce an approach that integrates an
explicit CDMA-ranging code reservation scheme with a Ranging Slot Selection
Window (RSSW) differentiation scheme. Simulation results are provided to
characterize the performance of the proposed mechanism.Comment: 15 pages, 6 figure
