为了在无线传感器网络中实现能量效率,已经提出了各种休眠调度方法。虽然这些方法可以使大多数节点休眠以节省能量,但它们没有充分考虑源自网络特定区域的数据量。提出了一种休眠调度方法,该方法将传感器网络划分为数量可调的区域,以确保每个区域中有多个节点保持活动,但要求所有节点都能够访问汇聚节点。然而,模拟实验的条件显示出一个问题,即所有活跃的传感器节点同时向汇聚节点发送数据包。本文报告了如何在新的评估中解决该问题,并表明所提出的方法还延长了网络寿命。
Various sleep scheduling methods have been proposed to achieve energy efficiency in wireless sensor networks. Although these methods can make most nodes sleep to save energy, they do not give adequate consideration to the amount of data originating in specific areas of the network. The authors proposed a sleep scheduling method that divided a sensor network into an adjustable number of areas to ensure that more than one node remained active in each area, but which required all nodes to be able to access the sink node. However, the conditions of simulation experiments displayed a problem in that all the active sensor nodes sent packets to the sink node at the same time. This paper reports how the problem was solved in fresh evaluations of the proposed method and shows that the proposed method also extends the network lifetime.
