How to sense and monitor the environment with high quality is an important research subject in the Internet of Things (IOT). This paper deals with the important issue of the balance between the quality of target detection and lifetime in wireless sensor networks. Two target-monitoring schemes are proposed. One scheme is Target Detection with Sensing Frequency $K$ (TDSFK), which distributes the sensing...
Recent years, with the emerging technology of cloud computing, the powerful computing and storage capability of cloud computing injects new vitality into wireless sensor networks (WSNs) and motivates a series of new applications. However, the data delivery from WSNs to Cloud becomes a bottleneck because of the poor communication ability of WSNs, especially for delay-sensitive applications, which limits...
Wireless Sensor Network (WSN) is a collection of large number of sensors with low-power transceivers effectively used for collecting data in various applications like environmental monitoring, healthcare, civil and military applications. Efficient data transmission protocols are required to reduce transmission delay and energy of sensors to increase lifetime of sensor nodes. Recent researches in WSNs...
This paper examines the effects of position-dependent delays of mobile actuator/sensor pairs when employed for the control of spatially distributed systems. It is assumed that a collocated pair moves freely within the spatial domain in order to minimize the effects of a moving source. A time delay that depends on the distance of the actuator/sensor pair from the base station is incorporated into the...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
Wireless networked embedded systems are becoming increasingly important in a wide area of technical fields. In this tutorial paper we present recent results on the design of these systems and their use in control applications, that have been developed within the project Reconfigurable Ubiquitous Networked Embedded Systems (RUNES). RUNES is a European Integrated Project with the aim to control complexity...
