Abstract
This paper focuses on reconfigurable systems for software defined radio applications in which the underlying hardware is dynamically reconfigured for packet processing of multiple protocols. However, due to non-negligible reconfiguration delay overhead, the physical layer may not be able to respond to all the packets scheduled by MAC layer. In this paper, we present a reconfiguration-aware spectrum sharing and spectrum access scheduling at MAC layer. We considered four protocols similar to WiFi, WiMax, GPRS, and WCDMA on a FPGA-based system. Our results show that the optimal solution outperforms the adopted existing heuristic for time slot scheduling by 13.29%.
