FPGA-Based Design of P-Detection 1-Persistent CSMA Control System

Abstract

In this paper, we propose P-detection and 1-Persistent CSMA/CA protocol. Using average cycle method, we established the mathematical model of the protocol. Through derivation, we obtain the throughput expression of this protocol. Simulation results show that this protocol improves the throughput and it is effective to enhance the system performance. Using this protocol, we completed the FPGA design of communication control system in WSN. The product passed waveform simulation and it is downloaded to the DB2 platform. Test results confirm the throughput of system has been increased, achieving the improvement of communication protocol for WSN.
