无线传感器网络的能量有效性一直是研究的热点问题。睡眠调度机制是一种有效的节点能量管理方法,能够延长整个网络的生命周期。本文提出了一种基于软件定义网络(SDN)的休眠调度算法SDN-ECCKN来管理网络的能量。在实现我们的算法时,采用EC-CKN作为基本算法。在SDN-ECCKN算法中,所有的计算都在控制器中完成,而不是在传感器中完成,节点之间没有广播,这是传统EC-CKN技术的主要特点。SDN-ECCKN的结果表明,它在能量管理方面的优势,如网络寿命,活节点的数量和网络中的solo节点的数量。
Energy efficiency in Wireless Sensor Networks (WSNs) has always been a hot issue and has been studied for many years. Sleep Scheduling (SS) mechanism is an efficient method to manage energy of each node and is capable to prolong the lifetime of the entire network. In this paper a Software-defined Network (SDN) based Sleep Scheduling algorithm SDN-ECCKN is proposed to manage the energy of the network. EC-CKN is adopted as the fundamental algorithm when implementing our algorithm. In the proposed SDN-ECCKN algorithm, every computation is completed in the controller rather than the sensors themselves and there is no broadcasting between each two nodes, which are the main features of the traditional EC-CKN technique. The results of our SDN-ECCKN show its advantages in energy management, such as network lifetime, the number of live nodes and the number of solo nodes in the network.
