无线传感器网络中,节点功率调节越大,网络连通性和抗毁性就越好,但是能耗也越大.为此,尝试找到抗毁性与能耗的折中点,既保证基本的抗毁性,又达到节能的目的.在分簇网络拓扑结构基础上,提出了一种基于概率母函数的功率控制算法,通过功率控制使之达到网络崩溃的临界点,以此与网络抗毁性达到很好的折中.仿真实验结果表明,该方法能找到此折中临界值,在节点数量较大情况下,该方法较使用加大固定功率的情况节省近50%的能耗.
In wireless sensor networks, the larger the node power regulation, the better the network connectivity and survivability, but the greater the energy consumption.Therefore, trying to find the compromise between destruction and energy consumption, both to ensure the basic resistance Destroyed, but also achieve the purpose of saving energy.On the basis of the topology of the cluster network, a power control algorithm based on probability mother function is proposed, which achieves the critical point of network collapse through power control, The simulation results show that this method can find the critical value of this compromise, which saves about 50% of the energy consumption when the number of nodes is larger than that of the fixed power.
