摘要
由于通信资源的有限性,传感器数据传输时速率会受到限制,在传统方法中通常将节点整体考虑,未区分单一节点和多个节点的性质差异,且忽视了节点在能量消耗与传输状态之间的关联,导致传感器感知结果不准确,影响了传感器数据决策力度。基于上述问题,提出了一种通信约束下传感器数据传输状态自动感知方法。计算传感器节点的绝对和相对剩余能量值。考虑剩余能量值的权重,构建能量感知模型。根据单个节点和多个节点的能量感知结果,结合拜占庭将军方法,将传感器网络中的节点视为将军,计算链路中各个节点的状态,以此判断数据传输链路中节点的正常和异常状态,实现传感器数据传输状态的自动感知。实验结果表明,该方法能准确感知约束条件下传感器数据传输量,且在通信时间300 s~400 s时出现了传输中断现象,提升了传感器数据的传输效率,证明了传感器感知数据的准确性。
Due to the limitation of communication resources,the sensor data transmission rate is limited,in the traditional method usually the node overall consideration,did not distinguish between a single node and multiple nodes,and ignore the node in the correlation between energy consumption and transmission state,lead to the sensor perception result is not accurate,affect the sensor data decision strength.Based on the above problems,this paper proposes an automatic sensing method of sensor data transmission state under the communication constraint.Computing the absolute and relative residual energy values for the sensor nodes.An energy perception model was constructed by considering the weights of the residual energy values.According to the energy perception results of a single node and multiple nodes,combined with the Byzantine general method,the nodes in the sensor network are regarded as general to calculate the state of each node in the link,so as to judge the normal and abnormal state of the nodes in the data transmission link,and realize the automatic perception of the sensor data transmission state.The experimental results show that the method can accurately sense the sensor data transmission under constraints,and the transmission interruption occurs when the communication time is 300 s~400 s,which improves the transmission efficiency of sensor data and proves the accuracy of sensor sensing data.
