在无线传感器网络中，能量效率是主要关注点之一，因为通常传感器节点依赖于小电池来操作。不合作事件是指在事件发生和消失时不容易监测的事件。因此，只有当传感器不断监测环境时，才能观察到它们。然而，能源效率是一个严重的问题，如果传感器总是ON的。在这项工作中，在无线传感器网络的能源效率和非合作事件覆盖之间的权衡进行了研究。我们开始与固定的监听和睡眠时间的计划，为一个单一的传感器节点和量化的事件错过率和归一化的平均功耗方面的性能结果。如果事件的统计信息是未知的，提出了一种基于“加法增加/乘法减少”规则的自适应方案，以适应与感测数据的睡眠时间表。固定和自适应方案都扩展到多个节点，并考虑到除了能量效率的网络的整个区域的覆盖。离散事件仿真结果验证了该方案的有效性。
In a wireless sensor network, energy efficiency is one of the primary concerns since typically the sensor nodes rely on small battery to operate. Non-Cooperative events refer to such events that they are not easily monitored as they come and go. As a result, they can be observed only if the sensors are constantly monitoring the environment. However, energy efficiency is a serious concern if the sensors are always ON. In this work, the tradeoff between energy efficiency and non-cooperative events coverage in a wireless sensor network is studied. We begin with fixed listen and sleep time schemes for a single sensor node and quantify the performance results in terms of event miss rate and normalized average power consumption. If the statistics of the event is unknown, an adaptive scheme based on a "additive increase/multiplicative decrease" rule is proposed to adapt the sleep schedule with the sensing data. Both fixed and adaptive schemes are extended to multiple nodes and the coverage of the entire area of a network is taken into consideration in addition to energy efficiency. Discrete-event simulations are carried out to demonstrate the effectiveness of the proposed scheme.
