Nodes in a wireless sensor network (WSN) are usually powered by batteries. Hence, it is important to efficiently expend the battery energy of each node in the WSN so that both runtime of the nodes and the lifetime of the WSN are prolonged. An event-driven energy-conserving scheme, called adaptive power-saving scheme (APS), is proposed. APS is able to adapt the sleep duration of a node to traffic variations...
In monitoring wireless sensor networks (WSNs), the occurrence of an emergency will generate a large amount of data in a very short time. Among them, some urgent information is more critical and needs to be transmitted out reliably as soon as possible. In this scenario, congestion is inevitable due to the limited resources, especially near the sink. To address this problem, we propose a novel reliable...
