A Secure Transmission Algorithm for Mobile Sensor Networks Based on Channel Random Interference Game Mechanism

为解决移动传感网安全传输领域存在的网络传输带宽较低、节点抖动现象难以控制等不足,提出了一种基于信道随机干涉博弈机制的移动传感网安全传输算法。首先,根据移动传感网覆盖存在的冗余特性,采取信道频率干涉机制对信道信噪比予以精确评估,以降低信道干涉对传输的不利影响,进而消除冗余数据并增强节点数据传输能力。随后,基于博弈退避机制提出了时间匹配方法,利用最低信道信噪比模型对节点数据传输周期予以调控,降低因数据重传输导致的网络拥塞,从而降低节点抖动发生频率。仿真实验表明,与常用的高效均衡分布机制的移动传感网安全传输算法和异构能量预测机制的移动传感网安全传输算法相比,所提出的算法具有更高的传输带宽及更低的网络节点累计抖动频次。

In order to solve the problems of low network transmission bandwidth and difficulty in controlling node jitter in the field of secure transmission of mobile sensor networks,a secure transmission algorithm for mobile sensor networks based on channel random interference game mechanism is proposed.Firstly,according to the redundancy characteristics of mobile sensor network coverage,the channel frequency interference mechanism is adopted to accurately evaluate the channel signal-to-noise ratio,so as to reduce the adverse impact of channel interference on transmission,eliminate redundant data and enhance the data transmission capacity of nodes.Then,based on the game backoff mechanism,a time matching method is proposed,which uses the minimum channel signal-tonoise ratio model to regulate the node data transmission cycle,reduce the network congestion caused by data retransmission,and reduce the frequency of node jitter.Simulation results show that,compared with the commonly used mobile sensor network secure transmission algorithm with efficient and balanced distribution mechanism and that with heterogeneous energy prediction mechanism,the proposed algorithm has the characteristics of high network transmission bandwidth and low cumulative jitter frequency of network nodes.
