摘要
基于电力传输线路的下一代物联网络,通信信息发生碰撞不可避免,因而提出了一种CSMA多址协议的改进型方案,TDMA/CSMA混合协议,并运用马尔可夫链定性定量地分析了各个因素对网络性能的影响。实验结果证明该方案有效地提高了信道的传输速率和系统的吞吐量,结果显示节点间发送冲突的概率大为减少。
In the next generation IOT is based on the power transmission line, collisions of communication are inevitable. Thus, CSMA protocol is improvedand TDMA/CSMA hybrid protocol is advanced. And then Markov chain is used to analyze the influence of the various factors on the network performance qualitatively and quantitatively. At last, the simulation results prove that TDMA/CSMA can effectively improve the channel transmission rate and throughput of the network, and probability of sending conflict is greatly reduced.
