Then Buffington spent an entire day manually, and painstakingly, applying "geo-fences" -- or virtual geographic perimeters -- around every school in Chicago by using their GPS coordinates.
Apparently the geographic, even the cosmic, perimeter, he goes beyond the sun.
For example, plants or animals occupying islands have a geographic range defined by the perimeter of the island.
Our full model, composed of pond surface area (sa), ratio of area of open water to area of emergent and woody vegetation (ow:ew), perimeter irregularity, and geographic isolation, was among 3 best approximating models for pond use by 9 of 13 groups (within Anatidae, Ardeidae, Charadriidae, Columbidae, Accipitridae, Laridae, and Rallidae) considered.
The beacon technology was great and we also chose to use geo-fence technology (virtual perimeters for real-world geographic areas) to action parts of the app to welcome people to venues.
We designed, implemented, and compared TFOR against existing routing protocols of VANETs (greedy-perimeter stateless routing (GPSR), geographic source routing (GSR), and enhanced greedy traffic-aware routing (E-GyTAR)).
We implement, analyze, and compare the behavior of our approach with existing approaches (greedy-perimeter stateless routing (GPSR), geographic source routing (GSR), and enhanced greedy traffic-aware routing (E-GyTAR)) using VanetMobiSim and Glomosim simulators. .
Greedy perimeter stateless routing (GPSR)[10] is a well-known geographic routing protocol in wireless multi-hop networks.
A third HPB algorithm, the perimeter-pairs variation, is proposed to bound the geographic extent of a candidate area within an approximated transmission range, based on the coordinates of the receivers situated farthest from a signal source.
