文章针对现有多信道动态接入协议在数据信道接入中存在冲突概率较大,数据报文传输成功率较低的问题,提出了一种基于声望模型的信道分配算法。该算法通过引入遗忘因子来反映历史经验对当前信道选择的影响,并根据链路接收方节点中可用信道的声望值大小,选取出期望传输成功率最高的信道。仿真表明该算法在相同网络环境中,能有效提高数据报文传输的成功率,增加网络的整体吞吐量。
In this paper, aiming at the problem that existing multi-channel dynamic access protocol has large collision probability and low success rate of data packet transmission in data channel access, a channel allocation algorithm based on reputation model is proposed. The algorithm introduces the forgetting factor to reflect the impact of historical experience on the current channel selection and selects the channel with the highest expected transmission success rate according to the reputation of the available channels in the receiver nodes of the link. Simulation shows that the algorithm can effectively improve the success rate of data packet transmission and increase the overall network throughput in the same network environment.
