Abstract
This paper presents a protocol to improve traditional CSMA protocol: DP-CSMA/CA protocol. In this paper, it is used in the design of WSN communication system based on FPGA. By using the method of the averaging period, we give the throughput parameters of this improved system. Simulation results confirmed that the DP-CSMA/CA protocol improves the system performance. The FPGA design is also effective to improve the performance of module in WSN. We completed the design of system based on DP-CSMA with FPGA. The test results show that: throughput are improved, packet collision is reduced, and channel utilization is improved in different load. This system has the features of simple circuit, high reliability, and programmable upgraded.
