Internet of Things (IoT) is considered to be the next revolution in the field of wireless communications. This concept involves mapping of physical world to virtual (cyber) world. It is achieved by interconnecting devices having sensing capabilities using unique addressing scheme and passing their collective information to the IoT cloud. However at present, these devices belonging to different technologies...
We have been developing wireless communication technologies for industrial applications. In industrial plants, there are many radio obstacles such as metal pipes and walls. Even in the severe environment, wireless communication has to be reliable and time has to be scheduled to maintain plant stability. For easy-to-use management, features of ad-hoc construction and low power management are also required...
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...
Expected growth in use and implementation of wireless sensor networks (WSNs) in different environments and for different applications creates new security challenges. In WSNs, a malicious node may initiate incorrect path information, change the contents of data packets, and even hijack one or more genuine network nodes. As the network reliability completely depends on individual nodespsila presence...
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...
