The Plazes ProjectThe Plazes.net website and API service are ceasing operation as of August 15, 2008With the acquisition of Plazes by Nokia now complete the Plazes development team is concentrating its resources building something new within Nokia, and it's very likely that the structure of the ... [More] Plazes API will change significantly. As such, the Plazes.net website and the Plazes.net API will cease operation on August 15, 2008.The Plazes.com site, and the Plazes.com API, will remain in operation for the time-being. Plazes is a geopresence service with a rich API that affords the ability to build applications and mashups that are "geo-aware." Plazes consists of a consumer web application, Plazes.com, and a developer-focused geopresence engine, Plazes.net. This project is a home for open source code that uses the Plazes API, as well as a place for developers to document applications, obtain sample code, and obtain answers to questions.

gt-mobisim

Simulator for generating mobility traces and query traces for large numbers of mobile agents moving in a road network. How to get gt-mobisim, along with source code, sample simulation configs & maps?QuickStart Example codes for using & extending the simulatorExampleCode DemoPlayback of ... [More] pre-generated simulation with this configuration xml. FeaturesDoes:generate mobility traces for mobile objects moving in a road network 100k objects, 10 minutes, flowing traffic speeds, velocity step-function representation, continuous time (no sampling) => ~235 MB trace simulation driven by an xml configuration file can be run as a text-mode only batch job (eg. on ssh-access-only Linux box) simple GUI, when running on graphical terminal vector map formats: ESRI Shapefile (.shp), eg. U.S. Census Bureau, TIGER/Line Shapefiles http://www.census.gov/geo/www/tiger/ GlobalMapper-exported USGS data (.svg), see: http://edc2.usgs.gov/geodata/index.php various mobility models on road networks random waypoint random trip 3 ways to represent continuous-time traces location step-function velocity step-function acceleration step-function locations of mobile objects at any time instance (ie. continuous vs. sampled locations) conversion from continuous-time traces to periodically sampled location traces ability to specify various parameter distributions Gaussian distribution with mean & standard deviation + min & max cutoff normal distribution with min & max generate query traces query creation query deletion Doesn't do:execution of client-side codes (ie. code that runs on simulated mobile users' phones) have a simulated server, or have simulated client-server communication [Less]
