Connected objects such as smart phones and wireless sensors becomes very attractive for our assisted daily life applications, because it offers continuous monitoring capability of both personal and environmental parameters. However, these systems still face a major energy issue that prevent their wide adoption. Indeed, continuous sampling and communication tasks quickly deplete sensors and gateways...
Several localization techniques have been proposed to identify the exact location of sensor nodes. Localization is important for computation of many applications such as routing in wireless sensor network. Energy preservation is a challenge in wireless sensor network and many algorithms have already been proposed. The localized node lifetime is maximized by using energy-efficient routing, use of minimum...
In this paper, we discuss the application of machine-to-machine (M2M) communications to healthcare. We analyze some of the enabling technologies of M2M and present an overview of the challenges, research opportunities, and standardization activities of this exciting area.
QoS is a key factor to the utility of Wireless Sensor Network (WSN) especially in the case of multiple sources data detecting with different time property. For environment detecting, there are not only same sensors just for one element but also heterogeneous sensors for multiple elements. Sometimes a single sensor has multiple functions to get several elements, which could be indicated to send the...
Information privacy is usually concerned with the confidentiality of personally identifiable information (PII), such as electronic medical records. Nowadays, Web services are used to support different applications which may contain PII, such as healthcare applications. Thus, the information access control mechanism for Web services must be embedded into privacy-enhancing technologies. Further as application...
