Fuzzy based Dynamic Bandwidth Allocation Scheme for OFDMA-PON Wireless Systems

Navjit Kaur, Satbir Singh

Abstract


An OFDMA-PON communication system works on same channel and signal on which weak or strong signal/data can communicate. Due to the mismatching of channel/signal, loss occurs and it creates problem to throughput of data in the system. Hence, an improvement is required to remove this limitation in OFDMA-PON system. But developing an efficient network due to an issue of subcarrier scalability in these networks is a challenging job, because OFDMA-PON has been considered as the next-level PON to improve the systems performance. An OFDMA-PON system outperforms over all other related systems, but not utilizes dynamic bandwidth allocation. Therefore, this research work proposed a fuzzy based DBA algorithm for OFDMA-PON system to enhance the performance of network. Experiment analysis indicate that the proposed technique significantly provide improve results over existing techniques.
