摘要: 摘 要: 移动传感器网络中,现有基于多副本传输的路由算法进行转发节点选择时大多依赖相遇节点的传输概率。针对这一问题,提出了一种基于虚拟货币的低能耗路由策略DTVC。根据节点的属性和数据消息的属性进行买方和卖方的定价并据此选择转发节点,为了控制数据消息的副本数,只有数据消息的源节点可以复制数据消息给满足条件的相遇节点,此外为了降低能量消耗,根据数据消息字段中的延迟容忍度以及sink节点广播的消息删除无效数据消息,从而减少不必要的能量消耗。在MATLAB上的仿真实验结果表明,与Flooding和FAD相比,DTVC能大量减少数据消息的副本数,从而减少网络中的能量消耗延长网络生命周期;与直接传输算法DT相比,DTVC的投递率至少提高15%。

Abstract: Abstract: For the problem that many routing algorithms in the mobile sensor network depend the transmission probability of the encounter node too much when the node transmits data message, a low energy routing policy DTVC(data transmission based on virtual currency) is proposed. When two nodes meet each other, the buyer and the seller determine the price of the data message according to node’s attributes and data message’s attributes. In order to control the number of replicas of a data message, only the source node of the data message can copy the data message to the meeting node that satisfies the condition.The deletion of invalid messages is based on the delay tolerance in the data message field and the message broadcast by the sink node, thereby reducing unnecessary energy consumption.The simulation results on MATLAB show that the proposed routing strategy DTVC can reduce the number of copies of the data message, prolong the network life cycle compared to FAD and Flooding, in addition improve at least 15% delivery rate of data messages compared to DT(Direct Transmission).
