This paper describes the main features of an advanced communication model aimed to enhance the protection of critical energy assets against man-made attacks (terrorism) or natural disasters. The proposed model is based on a hybrid network architecture, which combines the advantages of different wireless technologies, such as Delay/Disruption Tolerant Networking, Mobile Ad-hoc Networks, and Wireless...
This paper presents a cross-platform solution of smartphone-based mobile sink for wireless sensor networks, named uSink. With a cross-platform SD card, named uSD card, any smartphone with SD interface can be empowered with the capability to communicate with wireless sensor nodes. Furthermore, a middleware on mobile phone, named uSinkWare, is also designed to provide a typical mobile sink's functionalities,...
Wireless sensor network is applied widely in monitoring system of coal mine. An application environment of WSN in coal mine is analyzed to satisfy the data acquirement of mine monitoring. The result of analysis shows that routing protocols applied in coal mine should have four characteristics: data-centric routing mechanism, supporting query of geographic position information, low delay and high reliability...
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...
