—The IEEE 802.16 standard, or WiMAX, has emerged to facilitate high-bandwidth wireless access in realworld metropolitan areas, commonly referred to as 4G. In WiMAX, Hybrid Automa...
—Recently proposed beaconless georouting algorithms are fully reactive, with nodes forwarding packets without prior knowledge of their neighbors. However, existing approaches for...
Sensor networks are one important building block towards the realisation of context-aware applications. Suitable communication protocols and middleware solutions are necessary to ...
Abstract: A triangulated network of mobile units is modelled by means of a graph transformation system in which graph nodes are labelled with geometric coordinates and edges are la...
Wireless sensor networks are comprised of a vast number of ultra-small autonomous computing, communication and sensing devices, with restricted energy and computing capabilities, ...
