无线传感器网络由大量能量有限的微型传感器节点组成,因此,如何在保证无线传感网络中节点通讯区域覆盖质量和连通性质量的同时,又能延长无线传感网络的生命周期至关重要,为了解决这一问题,引入了区域划分对传感器网络节能效率影响的数学模型,提出一种基于节点权值划分的功率控制算法(A power control algorithm basing on weight measurement of nodes,简称NWMP),并详细论述了该算法的设计思想及步骤,最后,通过与其它功控算法的模拟仿真对比分析和性能评估,证明该算法能提高无线网络的网络吞吐量和延长网络的寿命.
Wireless sensor networks consist of a large number of micro-sensor nodes with limited energy. Therefore, how to prolong the life cycle of wireless sensor networks while ensuring the quality of coverage and connectivity in the node communication area of wireless sensor networks is crucial In order to solve this problem, a mathematical model of the influence of regional division on the energy efficiency of sensor networks is introduced, and a power control algorithm basing on weight measurement of nodes (NWMP) is proposed. Finally, through the comparative analysis and performance evaluation with the simulation of other power control algorithms, it is proved that the algorithm can improve the network throughput of the wireless network and prolong the life of the network.
