In recent years, the PM2.5 (particulate matter with a mean aerodynamic diameter of 2.5 micrometers or less) pollution has become a very serious problem in China. Currently, there are three types of monitoring approaches: government-led monitoring, Wireless Sensor Networks (WSN) approaches and Participatory Urban Sensing (PUS). There are three limitations in these state-of-the-art research approaches:...

The boundary detection of continuous objects has become an important research challenge in Wireless Sensor Networks (WSNs), where improving the accuracy of boundary and reducing the energy consumption are the primary factors to be considered. To address this challenge, this article proposes a tow-stage boundary area detection scheme in duty-cycled WSNs, and sensor nodes are deployed in a dense fashion...
This paper investigates the MAC protocol tailored for wireless sensor networks deployed in the intertidal environment (IT-WSNs) where the ebb and flow of the tide influence the packet transmission. Most packets fail to be delivered when the sensor node is submerged by seawater during high tide. To deal with it, an environment-aware electrode module is designed to detect the tide level and determine...
In this paper, we investigate the quality of information (QoI) maximization problem by jointly optimizing the sampling rate, packet-dropped rate, and transmit power in wireless sensor networks (WSNs). We consider a complicated but practical scenario, where various tasks with heterogeneous traffic are supported by one WSN simultaneously. Accordingly, the QoI maximization problem is formulated as a...
Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated with toxic chemicals. Water scarcity and water contamination has been one of the major issues faced...
Camera-enabled sensors deployed for visual monitoring will cover a region of the target field, providing information for many innovative applications based on wireless sensing. Actually, some areas of the monitored field may have more relevance than others, according to the characteristics of the applications, which may indicate that such areas need better coverage to avoid blind spots and achieve...
The use of sensing technologies in industrial environments has opened many possibilities for monitoring and control applications, driving much research efforts in the last years. Among the challenging issues related to industrial wireless sensor networks, efficient nodes deployment is a major concern since it can directly impact the way sensors operate, which has demanded proper solutions. When sensing...
In the wharf structure health monitoring systems, the systems exit low efficiency of data transmission and no effective data processing problems, which result in less effective reflecting the health status of the wharf structure. In order to improve the data transmission efficiency and make a better use of the data, an intelligent wireless sensor network (WSN) method and multi-sensor information fusion...
Advances in the information and communication technologies have led to the emergence of Internet of Thing (IoT). IoT allows many physical devices to capture transmit data, through the internet, providing more data interoperability methods. Nowadays IoT plays an important role not only in communication, but also in monitoring, recording, storage and display. Hence the latest trend in Healthcare communication...
Wireless Body Sensor Networks (WBSNs) are a low-cost solution allowing remote patient monitoring and continuous health assessment, thus reducing healthcare expenditure. In such networks, sensor nodes periodically collect vital signs and send them to the coordinator for fusion. However, sensor nodes have limited energy and processing resources and transmission is the most power-hungry task. In this...

Popularity of wireless sensor networks (WSNs) is increasing day a day where hundreds or thousands of applications are explored. In most of such applications, the need of gathering data periodically about the monitored environment beside the limited, generally irreplaceable, power sensor sources make energy conservation and big data gathering reduction two fundamental challenges in such networks. In...
Recent research on Low Power Wide Area Network (LPWAN) technologies which provide the capability of serving massive low power devices simultaneously has been very attractive. The LoRaWAN standard is one of the most successful developments. Commercial pilots are seen in many countries around the world. However, the feasibility of large scale deployments, for example, for smart city applications need...

This paper introduces REAPer, an adaptive energy harvester for microsources that can be configured and monitored by the supplied WSN node. We combine REAPer with an IdealVolting capable sensor node that can fully exploit the monitoring and control capabilities of REAPer. The efficiency and overhead of the...
The expansion of Internet of Things (IoT) and the evolution in communication technologies have enabled homes, cars even whole cities to be network connected. However, during an emergency incident, IoT devices have not been used to trigger emergency calls directly to healthcare providers mainly due to their constrained capabilities and lack of support session-oriented communications. Moreover, emergency...
