This paper presents a new MAC protocol the probability detection CSMA protocol for wireless sensor network based on the request-response mechanism. Builds the corresponding mathematical model using the average cycle method, and get the mathematical expression of systemic throughput through a rigorous mathematical derivation and makes the computer simulations. Simulation results show the correctness of the theoretical analysis and the effectiveness of the protocol; meanwhile, the protocol this paper presents increases the reliability and stability of the system through increasing RTS-CTS request-response mechanism and ACK handshake signal, thereby improving the systems transmission quality.
