【摘要】 无线传感器网络的能耗问题一直是研究的热点,睡眠机制作为一种有效的节能措施得到广泛的研究和应用。描绘网络中各部分剩余能源信息的“能量地图”,对延长传感器网络的寿命很有意义。基于广义随机Petri网给出了睡眠机制下传感器网络的能耗预估模型,构造出能量地图,为有效地利用能源提供了理论基础和数值依据。更多还原

【Abstract】 The energy consumption problem is always a critical issue in the research of wireless sensor networks(WSNs).The sleep mechanism,an effective energy-saving technique,is widely studied and employed.The Energy Map describing the information of the remaining energy in each part of the network,is useful for increasing the lifetime of the network.A GSPN-based model to predict the energy consumption of a WSN with the sleep mechanism is proposed for constructing the energy map,and the model provides the theory basis and data reliance for making efficient use of energy.更多还原
