متن کاملOn the Different Forms of Spanning Tree-based Broadcast Topologies for Mobile Ad hoc Networks
In this paper, we study the different forms of spanning tree-based topologies that could be used for efficient broadcasting in mobile ad hoc networks (MANETs). In this context, we consider the minimum distance-based, predicted link expiration time-based and the minimum velocity-based broadcast topologies, respectively referred to as MD-BT, LET-BT and MV-BT. The LET and minimum velocitybased bro...
متن کاملPatterns of animal diversity in different forms of tree cover in agricultural landscapes.
As tropical regions are converted to agriculture, conservation of biodiversity will depend not only on the maintenance of protected forest areas, but also on the scope for conservation within the agricultural matrix in which they are embedded. Tree cover typically retained in agricultural landscapes in the neotropics may provide resources and habitats for animals, but little is known about the ...
متن کاملThinking Like a Tree (and Other Forms of Ecological Thinking)
In the rain forests of Costa Rica, there is an unusual type of tree known as a “walking tree.” It is a strange looking tree. At the base of the tree is a tangle of roots, rising about a meter above the ground. It looks as if someone yanked the tree straight up out of the ground, leaving about a meter of its roots exposed above ground level. According to rain-forest guides, the walking tree actu...
