This project aim to perform a simulation that collecting sensor data of dogs by one server, and provide a web application by another server for visualizing the sensor data, including position, heartbeat, temperature, and so on.
The web application will automatically create 20 dogs at its start. Users are also allowed to add a new dog by clicking the Register Dog button located at the top-left corner of the map. Dogs will only run within a small rectangle at a varied speed which is determined by a Gaussian random function. The heartbeat and temperature will also vary as a dog travels. The faster it runs, the higher heartbeat and temperature will be. Dogs will only travels in straight line. If it hit the boundary of the rectangle, its direction will reflect. All the above varied values will be updated once per 2.5 seconds by default.
All the information of dogs is provided in this web application. The locations are presented on the map. Other information can be retrieved by clicking the a dog face. To dismiss the detailed information, click the same dog face one more time.
Click the Show Clustering button beside Register Dog and enter an integer as the number of clusters, the popup dialog will display a table with a column for each cluster displaying the dog’s id and weight.
The server that is responsible for collection sensor data provides several web services:
- Register a new dog:
POSThttps://sa9us.herokuapp.com/dogs - Get all dogs:
GEThttps://sa9us.herokuapp.com/dogs - A blank implementation for DELETE method:
DELETEhttps://sa9us.herokuapp.com/dogs - Get a specific dog:
GEThttps://sa9us.herokuapp.com/dogs/{id} - Show dog clustering by KMeans:
GEThttps://sa9us.herokuapp.com/dogClusters?k={integer} - Get a dogCluster contains dogs' ids and weights:
GEThttps://sa9us.herokuapp.com/dogClusters?showWeight&k={integer} - A simple visualization of dog position and cluster:
GEThttps://sa9us.herokuapp.com/dogClusters/rendered?k={integer}
Those RESTful services are built depending on Spring Web MVC framework, and should be normally worked on Java 8 environment.

The web application is tested on latest Chrome, FireFox, Safari, and an old iPad.
Rename DogSensorMonitor.war to ROOT.war and move it to webapps folder of Tomcat in Server #1. If a ROOT directory already exists in webapps, back up and remove it first.
Copy dogviz to the webapps folder of Tomcat in Server #2. Edit dogviz/js/config.js, change the value of property host of window.config to the host name of Server #1. Besides, property http_port indicates the http/https port number of tomcat server hosted on Server #1; and property isHTTPS indicates whether https protocol is adopted or not.
