代码传输是实现无线传感器网络应用重构的关键技术。首先研究传感器网络环境自适应应用重构(EAAR)模型的两种代码传输模式—拉模式和推模式,并结合两种模式的特点提出一种适用于分簇传感器网络的能量有效代码传输模式—基于簇的混合代码传输(Cluster-based Hybrid Code Transmission,CHCT)。在该模式下,簇头节点采用拉方式从基站获取代码,簇内节点采用推方式进行代码传输。仿真实验验证了方法的有效性并讨论了影响CHCT性能的主要参数。
Code transmission is the key technology to realize the reconstruction of wireless sensor networks. Firstly, the two code transmission modes - pull mode and push mode in sensor network environment adaptive application reconfiguration (EAAR) model are studied. Based on the characteristics of the two modes, an energy-efficient code transmission mode suitable for clustered sensor networks is proposed - Cluster-based Hybrid Code Transmission (CHCT). In this mode, the cluster head node adopts the pull mode to obtain the code from the base station, and the node in the cluster adopts the push mode for code transmission. Simulation experiments verify the effectiveness of the method and discuss the main parameters that affect the performance of CHCT.
