基于定价策略的无线网络节点能耗控制

Price-based energy consumption control of wireless network nodes

针对无线网络控制系统中由于节点能量消耗速度不同造成整个网络寿命变短的现象,引入经济理论,提出了一种基于定价策略的传输任务分配协议.高能耗的节点通过协议将传输任务外包给低能耗的节点,从而在增加低能耗节点的传输能量消耗的基础上,减少高能耗节点的传输能量消耗,平衡节点间的能量消耗,达到延长网络寿命的目的.利用Truetime1.5建立了该协议下无线网络控制系统的仿真模型,仿真结果表明提出的能耗控制协议能够有效地提高无线网络的寿命.

In wireless network control system （WNCS）, different energy consumption rates of network nodes reduce network life. To solve the problem, a protocol for the allocation of transmission tasks between network nodes based on economic theory and price scheme is put forward. Nodes with high energy consumption rate transfer its transmission tasks to nodes with low energy consumption rate. As a result, the network nodes energy is balanced and the network life increased through increasing the transmission energy consumption of nodes with low energy consumption rate and reducing the transmission energy consumption of nodes with high energy consumption rate. A wireless network control system simulation model with this protocol has been established by Truetimel. 5 and the simulation result shows that the proposed protocol can effectively improve the life of a wireless network.
